CHAPTER -I

1.0 INTRODUCTION

1.1 Preamble

India is one among the leading countries in mining and export of granite and is rich in granite

reserves. Geologically, the southern and eastern belts of the nation are abundant in Different

sakahades of granites are available in abundance in Tamilnadu, Andhra Pradesh, Karnataka,

Maharashtra, Assam, Bihar, Rajasthan Odisha, Meghalaya and Madhya Pradesh. Indian

granite stone has become the most sought-after and extensively used stone material and

massive structural works through the world and it is well known in the international market, not

only for its elegance and aesthetic quality but also for its durability

Granite is very hard crystalline, igneous or metamorphic rock primarily composed of feldspar,

quartz and lesser amounts of dark minerals. India has vast resources of granite, with about

110 varieties of different colours and textures such as black, grey, pink, multi-colored, these

verities are used to produce monuments, building slabs, titles, surface plates etc, However

popular verities are mainly found in south India.

Granite in the form of slabs and tiles has several attractive features, which inter alia, includes

extra -fine mirror polish, scratch-free glossy surface and durability. Granite can be compared

very well with floor and wall application materials such as ceramics and marbles.

Mining industry exerts both positive and negative environmental impacts. Negative impacts

cause environmental degradation. It is the responsibility of Mining Engineers, and

Environmentalist to documents these impacts separately so that these can be identified and

attempts may be minimize negative impacts and maximize the positive impacts for the better

development with less environmental degradation.

Environmental impact Assessment (EIA) and Environmental Management Plan (EMP) have

been considered as the most important tools/ documents which can be utilized by the project

proponent and governments regulating Agencies and the Public to clearly understand the

environmental implications of the proposed mining project with respect to sustained

development and to take action decisions in the interest of environment and national economy.

It also helps to analyze the techno -environmental feasibility of the proposed project

The lessee M/s Alliance minerals Private limited is in the Granite Quarrying industry for more

than two decades meeting the domestic demand and exports of Granite to industries which is

found to have use for monument, flooring slabs/tiles, Kitchen articles sculptures & for domestic

use. The lease area is found to have prominent exposures of colour granite covering most of

the quarry lease area .

1.8 METHODOLOGY OF REIA

Mining activity is carried out by Semi Mechanized open cast quarrying by using jack hammer

drilling &cutting by wire saw& blasting by low explosives if required.

The mining activities such as drilling, blasting, wire-saw cutting, and material extraction and

material transportation are expected to cause impacts on surrounding environment. The

impacts may beneficial or adverse. For assessing environmental impact due to this mine, an

area of 10 Km radius was split into two zones viz core zone and buffer zones. Th core zone

represents the mining lease area, which is potential source of pollution. The buffer zone

consists of the balance 10 km radius area. The methodology for each parameter of study is

discusses briefly below.

1.9 Micro-meteorology

Meteorological data has been collected using auto weather station located near the mine site

during the study period. The parameters like daily maximum and minimum temperatures,

relative humidity, wind speed and wind directions were collected for summer season (March-

May 2017) The baseline data was also assessed during the three months (March-May-17) as

per the latest environmental norms and AAQ norms, Wind speed and wind directions data

recorded during the study period were used for consumption of relative percentage

frequencies of different wind directions. The data was also used in air quality modeling for

consumption of ground level concentrations of dust contribution due to mining activates in the

core and buffer zones.

1.10 Ambient air quality

Ambient Air quality data from the core and buffer zone village of 10 km radius is obtained

through a network of Eight ambient air quality station’s the location of air monitoring stations

were fixed after considering the predominate wind direction. Out of the eight stations, one

station represents the core zone station and seven stations represents the buffer zone, the air

samples were collected continually for 24 hrs. the paraments such as PM2.5, PM10, SO2, NOX

were monitored. The frequency of sampling is 2 days in a week for a period of 3 months. The

standard procedures and methods as outlined by central pollution control board (CPCB), and

Bureau of Indian standards (BIS), were adapted for chemical analysis.

1.10.1 Noise Environment

Noise monitoring locations were fixed after identifying different noise sources in buffer zone.

Noise levels were recorded at an interval of 30 minutes during the day and night times to

compute the day equivalent levels. The noise levels were measured in dB (A).

1.10.2 Land Environment

Soil samples were collected during the month of March-May 2017 from seven locations and

representing various land uses in and around 10 km radius of the mine site. Soil samples were

collected using core cutter and Augur combination up to 30 cm depth, which represents top

soil. Standard procedures were followed for sampling and analysis to determine the fertility of

soil. Land use and Land cover pattern of the study area has been assessed though standard

classification techniques.

1.10.3 Biological Environment

Data on biological environment (terrestrial and aquatic flora and fauna) were collected from

various Government departments such as forest, Agriculture, Fishers and animal husbandry

within 10 km radius of the mine site.

The status of flora and fauna with in core zone and buffer zone was studied by a biology expert

by conducting field surveys and identifying different species that are prevalent with in 10 km

radius of the mine site during March -May 2017.

1.10.4 Socio -Economic Environment

A filed survey was conducted among the villages falling within the 10 km radius from mine

site. Information regarding the population, family status, occupation, literacy level and

amenities etc. was also obtained from the district statistics records to determine the

developmental activities to be undertaken by the mine management. Such developmental

activities would result in upliftment of the economic status in the area.

1.11. Identification, Prediction and Evaluation of Impacts

Various operations involved in mining have been studied in detail to identify the area’s leading

to impact / change in environmental quality. ISCST3 Model was used for prediction of impacts.

The over all scenario estimated has been checked for compliance with various statutory

reequipments/ standards.

1.12 Formulation of Environmental Management Plan

Based on the existing environmental status and quantified impacts, a detailed environmental

management plan (EMP) has been formulated for implementation at various levels by the

mining management.

2.4 Geology

2.4.1 Regional Geology


Telangana State.


P a g e | 9

Regionally the area in comprised of rocks of Achaean Era represented by garnet biotite gneiss,

amphibolite and banded magnetite quartzite. The regional trend of foliation is NNE-SSW with

steep dips to WSW and also to ESE. The rocks quarried are basically variants of Granite and

younger Dolerite intrusive, commercially known as black granites. The peninsular Gneissic

complex occupies major part of the district. The Jagityal town, the district headquarter is

situated on porphyritic granite which occasionally shows signs of metamorphism. This setup

is traversed by dolerite intrusive. Further, the entire association is overlain by the Pakhal Super

group consisting of meta sediments. The Gondwana super group constituted by sediments

rests over the other units unconfirmable.

Stratigraphy: Stratigraphically the area belongs to Proterozoic Era and very little to Achaean

Era. The Stratigraphy of this region is as follows:

Lithology:

In the Quarry lease area, is seen as slightly boundary on the top and has sheety nature at<1m

below the top level. The rock is coarse grained with less joints. It is slightly reddish in color

due to the presence of pink feldspar porphyry and gives glossiness, after cutting and polishing.

Hydrogeology:

Much of the area is dry without good water yielding structures. The water table is at +30 m

depth. The recharge structures are very less. A few tanks are seen around the lease area and

the nearest one is 1.5km north east of the lease.

Geo –technical properties of the rock by hand lens or a microscope:

The top 1.0m of the outcrop is weathered. Top surfaces of the rock sometimes show alteration.

Based on these features, the degree of weathering of this rock can be graded as ‘B’. But the

fresh rock is ‘A’ grade.

Degree of weathering Description Grade

Slightly weathered There is discoloration of the rock material and is friable. This is the top material up to 1m

Fresh rock No visible sign of weathering of rock material A

2.4.3 Details of Exploration

Details of prospecting:

The quarry lease area has been surveyed by total station. The rock body is exposed as a

sheet rock with occasional boulders. The contour Interval has been taken as 5m. ABM is

considered as 100MRL.The topographical cum geological plan of the area is given on 1:2000

scale (Plate #3). the overall pattern of the lease is sinuous hence, the area has been divided

into blocks for the calculation of reserves.

A) Previous prospecting results:

Nature of quarry:

As the area is already under the quarrying activity and producing considerable quantities of

color Granite, since quite some time, this area is considered as proved one.

Technique adopted:

Hydraulic excavator and compressor operated jack hammers were deployed for cutting the

rock. Close spaced drilling of 0.2m is adopted along a straight line and charged with low

explosives to avoid feather cracks.

Material Produced:

The material produced for the last five years is given in the following pages.it has yielded

blocks of 1.5m X1.5mX1m and blocks suitable for monuments i.e. 1mX0.5mX0.5m

2.4.4 Estimation of Reserves & Grades

Economic/Marketable reserves:

It is calculated that 49,28,000 Cu.m of stone is available in the proved category up to 300 RL,

above the ground level after the removal of 1m thick weathered material. Net mineable

reserves are calculated to be 6,83,275 Cu.m at the recovery rate of 15 %, considering the

structural, textual and mineralogical aspects of the rock. Considering this approximately

28,847 primary/rough blocks of 4m X 3m X 2m size can be extracted from this mine. It is

estimated that about 60 primary blocks can be mined per year. This is based on the degree of

mechanization.

The volume calculated by the cross-sectional method.

10 sections have been drawn and the area is calculated using the centimeter graph. This when

multiplied by the influence of the section gives the volume. (Up to 300 MRL)

Reserves: Reserves have been calculated by cross sectional method.

Cross Sectional Method: A cross section has been drawn considering the trend of the

contours (A-A’ to F-F’ in the map-Plate 3). The area covered by the influence of the section

on either side gives the volume The influences is calculated considering the entire area.

Mining Methodology:

The method of mining is Open cast semi mechanized method by using drilling & blasting by

low explosives and wire saw cutting and developing multiple benches with 6m height each.

Sheet rock zone: if sheet rock is encountered,

Splitting of primary block from mother rock: The mining will be followed in the form of key

cut. This involves

Loosening of the primary block from the mother rock: As the primary block is 43 X 3m X

2m low benches method is used. Where in vertical and horizontal cutting is done by diamond

wire sawing. Blasting is done using low chemical explosive like ECM/CaOH. Vertical cutting

also will be done with diamond wire sawing in the face attached to the mother rock. Horizontal

cutting: If horizontal joints are available they will be made use oy if not, horizontal cutting will

be done by diamond wire sawing.

Secondary Cuts: This involves shaping and squaring of primary block. When the bench

height is less than 6m, low bench method is adopted where in vertical cutting is done by drilling

and blasting will be done using low chemical explosives like ECM/CaOH. Secondary splitting

and Segment tipping. This is done by drilling closed space holes (along a line) down to depth

and the secondary block will be removed by easily by just pulling it with the help of proclain.

Transportation to dressing yard: Transportation will be done by using cranes and tippers

depending upon mechanization. Blocks will be removed from mine site to minimum dressing

yard.

Block dressing: the commercial blocks will be dressed at the corners with minimum wastage.

By the end of the first five years, part of north eastern portion of the lease area will exploited.

A 22’ ramp is made adjacent to the quarrying area in the central part to transport blocks and

rock waste. Pictorial representation of all these details is given in the plate no 5. Uniform

production of 34 primary blocks of 4m X 3mX 2m size is planned every year. Keeping the

demand and machinery in to consideration.

If sheet rock is encountered

Separation of large primary blocks from the mother rock by pre-splitting (primary cut):

The rock is exposed as a sheet. Diamond wire saw will be used to cut primary block from the

mother/insitu rock. The size of the primary block is 4m X3m X2m (l x W x B) i.e. 24 m3.

Subdivision of large(primary)block into secondary blocks (Secondary cuts):

Secondary blocks of 2m X1.5m X 1.5m will be cut. Secondary cutting will be done using

compressors (6-7 bars,1X900), down the hole jack hammer. The other machinery required is

tippers for transport.

Production of commercial blocks by production cuts:

Commercial blocks will be produced by selecting the blocks free from any mineralogical or

structural defects. They will be marked and they require only segment tipping. Finally blocks

of 2m X 1.5m X 1.5m ((l x W x B) and 1.5m X 1.5m X1m sizes will be cut depending on the

requirement. If it for monuments 1m X 0.5m X0.5m will also be cut.

Drilling and Blasting:

Drill-hole for primary and secondary smooth blasting: Blasting will be done only when it

is necessary, Using low explosives. Primary blocks will be cut mainly by “Rig-bore” drilling on

to opposite sides and on the other two sides it will be drilling. Bottom portion of the block will

be cut by diamond wire sawing. The rig -bore will have a radius of 12cm.The hole depth will

P a g e | 16

be to the entire 6 meters and it will be uniform for all the holes. At a time eight drill holes will

be blasted.

a. Drill hole diameter: Drill hole diameter will be 32mm and 37.5mm

b. Depth and inclination of the blast holes: Depth of the boreholes will depend upon size of the

boulder and they will be vertical

c. Spacing and Burden: the spacing and burden will be 0.2m and 1.6m respectively, close

spaced line drilling is also preferred. ion

d. Stemming and charging of the blast hole: Whenever blasting is done, the ultimate holes on

either side are left uncharged to prevent the formation of feather cracks in the block. The

stemming and charging will be done under the guidance or supervision of an experienced

blaster

e. Explosive Type: Low-Density chemical explosives like ECM/CaOH will be used sometimes

smooth blasting may be done using silent non-explosive demolishing agents like Acconex.

f. Quantity of explosive used: The charge concentration of the explosives will be between 10-

40 grams per linear meter.

Repeated charging and blasting of the same holes will be avoided.

By following the all above said measures it is targeted to achieve clean breakage along the

holes with very less amount of toe.

Transportation of the blocks from quarry to yard and to destination:

Heavy duty trucks 2 in number, are used for transportation of rough blocks from the quarry to

yard or to destination (i.e. port).

Storage and handling of the Explosives:

A non-explosives chemical are used no magazine is proposed. However, the explosives will

be procured on time basis and will be stored under safe custody, the explosives will be handled

by licensed and experienced personnel engaged by the company.

Dressing

Dressing of dimensional rough blocks for export:

Dressing is made along edges, such that edges will not be sharp, to facilitate easy handling.

Dressing is also done to remove angularities and irregularities along the edges. As thr rock is

homogeneous, required size of the blocks for export are expected. However quality elevating

factors like move design, uniform texture etc. will be seen before cutting block. The size of the

blocks will be 2m X 1.5m X1.5m and 1.5m X 1.5m X1m. Depending upon the demand still

similar sizes can be cut.

Dressing of rough blocks in the quarry for domestic processing plant:

Dressing is made along the edges, so that edges are not sharp, which may cause injury while

handling. Dressing is also done to remove angularities and irregularities along the edges. The

rough blocks sizes of 2m X 1.5m X1.5m and 1.5m X1.5mX1m if found not suitable for export

purpose, will be dressed to still smaller sizes like 1m X1mX1m and 1m X 0.5mX 05m and will

be used for domestic consumption.

Dressing of rejected rough blocks for value addition:

Blocks which can have the dimension of more than 2 ’X 2’X 2’ are separated and dressed

down to 2 ’X 2’X 2’ size, which can be used in domestic market. This is done in accordance

with conservative of granite.

2.6 HANDLING OF WASTE AND SUBGRADE MATERIAL:

Solid wastes:

Removal of weathered rock and the rock waste is the only solid waste that will be generated

from this mine. It will be removed and will be dumped along the northern portion of the lease

area where already a dump exits, which will be simultaneously used during mine reclamation.

from the solid waste that is generated during the primary mining activity blocks that are useful

for cutting tiles and slabs will be separated. The remaining material will be used as road metal

or building material. All the care will be taken to minimize the waste generation at the source.

Estimated waste quantities that will be generated n the next 5 years plan period.

Total 51,408

Estimated waste quantities that will be generated over the entire 20 years lease period:

The lease given is 20 years. the lease will expire on 20-12-2029.It is estimated that 60 primary

blocks 4mX3mX2m can be produced in a year. Waste of 7344 m 3 will be generated per year.

Thus the waste generation for the entire lease period i.e. 17 years will be 1,24,848 m3.

Measures to be adopted for solid wastes:

From the waste generation blocks of 2’X2’X2’ are separated and kept at the dump site for

subsequent dressing and will be used for domestic consumption. The waste of various

dimensions less than 2’X2’X2 will be used for back filling the quarry areas., It is also supplied

to crushing plants and is used as road metal. The left-out waste will be used for back filing the

quarry, which will be covered with soil added with soil conditioners and mine will be reforested.

Liquid Wastes:

Mine drainage waters: During the first five years quarrying will go the depth of 6m from the

present level of mining. The floor level of mine is not going to affect the static ground water

level, which is 25m bgl. Hence there is no chance of ground water pollution. During the

monsoon period, water if gets stagnated, will be drained out.

Run-off from water dumps and measures proposed to arrest waste run-off: To prevent this, it

is proposed to grow small bushes and tiny plants which will prevent soil erosion. Further, the

run-off the dumps will be channelized by digging small trenches and channels around the

dumps and will be made to pass through a few siltation and channels around the dumps and

will be made to pass through a few siltation tanks. In case silt is carried by the run-off it will

get deposited in the siltation tanks, which will be desilted is carried by the run-off it will get

deposited in the siltation tanks, which will be desilted periodically. And care will be taken to

see that the fines are not washed away along with the run-off.

Excavation of drainage ditches all around the quarry to divert all surface drainage: All around

the quarry surface ditches or channels will be made to divert all surface drainage into the

adjacent fields. As there are no toxic material in the water it will not have any ill effect on the

crops.

Utilization of run-off for general surface use or discharge into surface drainage network only

after meeting with prescribed discharge standards and for agricultural purpose on the surface:

Surface run off will be channelized first and will be allowed to pass through siltation tanks to

arrest the suspended solid particles(SSP) As the rock involved in mining does not have any

toxic materials, the water leaving the mine also will not have any toxic material. However

periodic checks will be let into the adjacent fields. But, before allowing the water to fields, it

will be let into the adjacent areas within the mine.

Open cast mining activity causes some adverse impacts on the surround environment un less proper environmental management plan is adopted. Selecting suitable sites for mining and adopting the guidelines prescribed by the ministry of environment and forest (MoEF) and Indian Bureau of Mines (IBM), one can minimize the major possible impacts. The fallowing aspects have been studied to identify the possible impacts while achieving the total production of 9600 Cum/Year. The magnitude and significance of the environmental pollution caused by mining depends on method of mining, scale and concentration of mining activity. The Impacts on air environment from a mining activity depend on various factors like production capacity machinery involved operations and maintenance of various equipment’s and vehicle. A part from these, there will be other activates associated viz transportation of mineral and waste, stocking Facilities and dump management within the mine lease area that may contribute to pollution. 3.1.4.1 Air Emissions Prediction of impacts on air environment has been carried out taking in to consideration of the proposed production and increase in emission. The proposal is for production of 9600 CU.M/yearly of color




P a g e | 27

Granite, two estimate the impact the production 9600 CUM/Year has been considered. The proposed mining is carried out by semi machined open cast method by using drilling and blasting and wire saw cutting. The air borne particulate matter is the main air pollutant contributed by mining and mineral process operation. Resultant ground level concentration for the prevailing meteorological conditions, using the ISCST 3 model were estimated. 3.1.4.2 Quantitative estimation of impacts on Air environment An attempt has been made to predict the incremental rise of various ground level concentrations about the base line status in respect of air pollution due to proposed mining production for a total quantity of 9600 CUM/Year of color Granite. The mathematical model employed for predictions in the present study is ISCST3 model, which was approved by united states environmental protection agency for mining applications, The industrial source complex – short term model(ISCST3) is computerized air quality model specifically designed for computing concentration and deposition impact of various emission sources. The Model is based on the well-known gaussian plume formulation from computing concentrations and also the model has been specifically adopted to incorporate an improved gradient transfer deposition algorithm. Emissions for each source are apportioned in to a series of particle size classes gravitational settling velocity and deposition velocity are calculated. Salient features of ISCST3 model are given here under

• Drilling and blasting operation are considered as point sources

• Excavation operation are considered as area sources

• Transportation of material on haulage roads has been considered as line source The predicted ground level concentrations for study period computed using EPA approved ISCST3 model are plotted as isopleths

3.1.4.3 Sources of dust emission Mining is carried out by open cast and under-ground method by using drilling and blasting. Based on the various operations involved in the production of minerals, the various emission sources have been identified as given below.

a) Point sources b) Area sources c) Line source

Drilling operations of the mine are considered as point sources. Extraction of minerals from mine, are considered as area sources. Transportation of material from mining benches to various end a point are considered as line sources the impact of above sources on air environment is discussed below.

a) Drilling and Blasting Drilling and blasting is required to mine the minerals in this area. Blasting will have done using small diameter slurry based low explosives. Air pollutants will be generated during blasting are in the form of particulate matter. Blasting will be carried out during day time only and will be avoided during high wind period. The concentrations due to instantaneous blasting will be high and ease confined to a maximum distance of 100 m from the area of the blast around each pit. These concentrations will not be immitted continuously. However, presence of personal near the blasting site during blasting will be totally avoided. So, the impact of blasting on the air environment will be minimal

b) Extraction and loading Extraction and loading will be done machinery loading activity of mine operation is contributing to the area source emission and the extent of influence of this operation is about 100 m2.




P a g e | 28

c) Haulage and transportation In the operating mine the excavated material form mine face to the consumer is transported by lorry /Tippers. The tipper will be well maintained so the exhaust smoke does not contribute abnormal values of noxious gases and un burnet hydro carbons. The other source of air pollution is due to the dust generated during the moment of tractor on the haul road. In the operating mine, the excavated material form mine face to the processing yard Is transported by tractors. The tractors are well maintained so that exhaust smoke Does not contribute abnormal values of noxious gases and un burnet hydro carbon the other sources of air pollution is due to the dust generated during the moment of Tractors /vehicles on the haul road. The above source, which include blasting, excavation haulage for transport of mineral will contribute to dust pollution in the air. The dust generated in the operating mine is that of topsoil.

3.1.4.4 Emission details All the emissions discussed above are qualified production 9600 CBM/Year of color Granite. The existing air quality levels are covered in the base line scenario. The emissions are computed based on AP-42 emission factors operation hours activity rate wind speed and moisture content have been considered for estimation of emissions from area sources.

P a g e | 29

For the prediction of worst – case concentration, the sources mentioned in the above paragraph are assumed to be under simultaneous continues operation for 24 hours. Hence, the concentrations predict are considered may occur in the worst case. The Number of working days has been taken 250 days with 8 hours of operations/day. With control measures, the emission has been taken un controlled emission at1/3 of the controlled emission for excavation of mineral and transportation of the same. 3.1.4.6 SUMMARY OF PREDICTED GROUND LELVEL CONCETRATIONS (GLC’S) OF PARTICULATE MATTER(PM10) Ground level concentrations due to the mining activities have been estimated to know the incremental raise and extent of impact in the study area. The major activity is mineral transport from the working pit to the consumers. The dust levels re distributed all along the transport route in the mine area. The maximum ground level concentration is estimated to be about 5.230 mg/M3 within the mine area. The isopleth showing the Ground level concentrations of particulate Matter P.M10 due to emission from mine is given figure3.3 Predicted value superimposed on the existing base line value gives the overall scenario, which would prevail during study period once mine is operated for the proposed production.

3.1.5 ENVIRONMENTAL MANAGEMENT PLAN (EMP) Ideally, an environmentally sound project should have zero adverse impact, which for all practical purpose is difficult to achieve for a developmental project like the present one. The interpretation of EIS of the proposed project activates made in this chapter revels that the overall impact of the project on the environmental, though negative, is only marginal. With some remedial measure of the proposed project activities, it is possible to further mitigate the potential impacts. The plan processes several remedial measures from the environmental angle which if adopted and implemented would minimize the potential impacts without affecting the mine productivity. Air pollution control measures Air pollution control measures would be of three types namely (i) Dust suppression system(DSS) (ii) Vehicular emission control (VEC).




P a g e | 30

Dust Suppression system (DSS) Adequate water sprinkling arrangement would be provided to suppress dust emissions form the haul road, mine working faces, stockpiles and other areas susceptible to dust emissions due to surface wind. It is proposed to deploy water tankers fitted with pressurized multipole spray system including side sprays. On the haul roads which cause maximum dust emissions, water shall be sprinkled on the road mixed with dust suppressant chemical to enhance the soil moisture retention capacity. These chemical shall be non-toxic, non-corrosive and of neutral PH. Periodically the road shall be graded spillage material shall be removed to the earmarked areas. Source emission control: In an open cast mining operation s such as excavation and handling of minerals, generate appreciable levels of fugitive dust. In order to control the dust emissions at the above source it is proposed to adopt the fallowing work practices on routine basis. The minerals bed shall be moistened to certain extent to minimize dust arising during various operations such as excavation and transportation. Vehicular Emission control (VEC) Vehicular emissions from diesel operated transport equipment can be contained, by avoiding idle running and overloading of the engine. In addition, the engine shall be periodically serviced to ensure proper tuning and exhaust gases monitored on a regular basis to check smoke and CO levels.

3.2.2 Anticipated Impact due to noise Noise will be produced during operational phase mining due to drilling blasting compressor, moment of tractors and other machinery. The noise generated by the mining activity is dissipated with in the core zone. Since, the mining and allied activities will take place only during day time, the increase in noise levels will be only during day time. Noise level in the work zone varies from 70 to 75 dB(A), except during blasting, which is carried out after the end of working shifts, personal exposure is less than 80 dB(A), because operators sit in closed cabins. Noise contribution from work zone to the nearby buffer zone villages will be insignificant because the villagers are situated at the distance and the mining activities is carried out only in the core zone which is hilly undulating land. The development of green belts will further reduce noise in both core and buffer zones. Blasting Effects In accordance with DGMS regulations, the lease area will maintain a safety belt of 500m distance from the quarry. There is no human habitation within the core zone. However, keeping in view the presence of habitation behind the core zone and during blasting, which are discussed in EMP. Comparison of the estimated ground vibrations with permissible limits prescribed by DGMS, Dhanbad, show that, with 30kg of explosive charge per blast round, the vibrations are within limits for all types of existing structure both in core zone and buffer zone. 3.2.3 PROPSED MITIGATING MEASURES Noise pollution control Mine workers are generally exposed to higher risk of hearing impairment than most other industrial workers. The circular of directorate general of mines safety (DGMS) prescribes a permissible level of 90 dB(A) for exposure without any protection for a maximum duration of 8 hours DGMS has recommended 115 dB(A) as the noise level at and above which appropriate ear protection device should be use and 140 dB(A) as the level where no worker should be allowed to enter even with ear protection device. Nosie control measure at the mine can be broadly clarified in two three types, namely (i) administrative control and (ii) engineering control and (iii) personal hearing protection A brief outline of each of the control measure is outlined below Administrative Control The staff roster shall be so planed that none of the workers working in noisy environment gets over-expose to noise beyond the permissible duration. Other administrative control techniques include:

• Providing proper noise proof enclosure for the worker separated from the noise source and noise prone equipment’s

• Provision of quiet areas, where employs can get relief from work place noise. Areas used for work breaks such as rest rooms, canteen shall be acoustically treated to minimize background noise.

Engineering Control The effective attenuation of noise can be achieved by source control measures such as

• Selection of quieter mining equipment’s and machineries

• Retrofitting additional noise control device as required

• Carrying of blasting during day time. Blasting shall not be carried out in stormy and rainy weather and during lighting.

• Reduction in the secondary blasting also reduces the noise as well as vibration due to air blast




P a g e | 34

Personal hearing protection Personal hearing protection can be considered as an accepted method of minimizing the impact in a noisy environment. Personal hearing protection devices including earplugs with glycerin-soaked cotton and earmuffs shall be provide ad to workers exposed to noise.

Water quality The results of the analysis of surface water are compared with IS 2296 1982 norms and the results of the analysis of Ground water are compared with 1S10500 1991 norms and the result of surface water and groundwater for the above locations is given in Annexure -B 3.3.1.1 HYDROGEOLOGY STUDY / SURVEY ON SUSTAINABLE WATER RESOURECES FOR THE PROPOSED COLOUR GRANITE MINE BELONG TO M/S ALLIENCE MINERALS PVT LTD.OVER AN EXTENT OF 29.00 Hect. IN SURVEY NO. 207 OF NANDAGARI (V), PEGADAPALLI (M), JAGITYAL (D), TELANGANA. Introduction: M/.s Alliance minerals Pvt Ltd., of Karimnagar District of Telangana, has been granted Quarry lease over an extent of 29.00 Ha for mining of Color Granite, in Sy no 207 of Nandagiri (V) Pegadapally (M) Jagityal (D), Telangana. The QL area is surrounded by 4 other QL’s (12.00 Ha, 2.00 Ha, 1.0 Ha and 2.00 Ha) in the same Sy.no. which have got Environmental Clearances along with CFE and CFO. The Firm intends to produce color granite to the tune of 9600 cum/year. The QL area and its environs with the radius of 10 km was explored and studied to evaluate the sustainable water resources watershed is to be taken as the mapping unit but as the area of interest is small the 10 km zone is considered in this study. Location: The study is situated at the intersection of 180 39’ 31’’ – 180 40’ 04’’N and 790 02’ 50’’ – 79003’03’’E and is falling in the SOI Topo sheet 56 N/2, The project site is situated 1.1 Km Northeast of Nandagiri village and well connected by road motorable in all seasons. The Nearest Railway Station is Peddapally. Topography: In general, the area is plain with isolated hillocks. Sometimes they may rise gently, presenting a rugged topography. Their height ranges between 330 m and 400m above the MSL. The quarry lease area is small hill of about 65m and is at 320m above MSL. There is no major stream in the near vicinity. The Kakatiya canal runs 0.75km north of the lease. A small stream flows 1km north of the lease. The nearest tank (dry) is about 1.5 km north east of the lease. Drainage: During the first five years quarrying will go to death of 6 meters from the present level of mining. The floor level of the mine is not going to affect the static gourd water level, which is at 25 meters BGL. hence there is no chance of ground water pollution, During the, monsoon period, water, if gets stagnated, will be drained out. The benches will made with an inward slope to facilitate run off faster on to the mine flour. Small bunds, garlands and silting tanks also will be constructed to minimize inflow muddy water carry fine material. The average annual rainfall of the area is 950mm.

joining the rivers, tributaries, and tanks based on topography. Understanding the importance of drainage depends on the purpose and the objective of the project. For the present study purpose the following factors have to be understood and extracted from the study of the drainage pattern. Drainage network helps in delineation of watershed. Drainage density and type of drainage gives information related to runoff, infiltration relief and permeability.

Dendritic drainage indicates homogenous rocks, the trellis, rectangular and parallel drainage patrons indicate structural and lithological controls. The course drainage texture indicates highly porous and permeable rock formations: various fine drainage texture is more common in less previous formations. Weathering profile controls of ground water and above all discharge of surface water along the major streams and rivers. Fractured patron and other structural features control drainage patron in hard rocks. Slope/gradient of area coupled with drainage density decides the weathering profile. These two factors synthesized with rainfall (of a given area) provide information on the ground water potential (weathering profile ground Structural factors) and discharge of surface water along the streams. Weathering profile increases ground water potential, slope/gradient together with runoff controls the thickness of weathered zone. Major faults, lineaments sometimes connect two are more watersheds (Drainage Basins) and act as conduits (interconnecting channel ways) Flow of groundwater along these week zones is an established fact. A proper understanding of the major faults, their influence on ground water would be affected by the water pollutants. Survey of India Topo maps, Satellite date of summer season are the main input data for preparation of drainage map. The drainage map is prepared using toposheets of survey of India on 1:50,000 scale and updated using latest satellite data wherever deviations and new developments are observed. Step I: All the rivers its tributaries and drainage network shown on the toposheets are captured. The boundaries of all rivers/ water bodies with names appearing are captured from toposheets. The drainage is drawn from whole to part, i.e., from the river to tributaries to first drains to second order drains to third order drains. Step II: Based on the post monsoon satellite image extent of water spread and dry parts are updated. The water bodies which did not exist at the time of survey of toposheets, if any are also captured based on satellite imagery. The drainage map of study area has showing in figure 3.6

Land Use: Within the 10 Kms radius of the proposed project study area the crop land is covered over an area of 202.21 Sq.km and water bodies is occupying an area of 19.154 Sq. km. The land that is under Non-agricultural usage is 46.472 Sq. km. the waste land occupying an area of 79.756 Sq.km. Irrigation is mainly through surface and ground water. About 55 percentage of the net area was irrigated under surface water and 45% of area under groundwater (source: CGWB published report) most of the soils observed were black clayey to loamy soils. Geology: Regionally the area in comprised of rocks of Archaean era represented by garnet biotite gneiss, amphibolite and banded magnetite quartzite. The regional trend of foliation is NNE-SSW with steep dips to WSW and to ESE. The rocks quarried are basically variants of granite and younger dolerite intrusive, commercially known as black granites. The peninsular gneissic complex occupies major part of the district. The Pakhal and Gondwana supergroups occur in the eastern part of the district. The Karimnagar town, the district head quarter is situated on porphyritic granite which occasionally shows signs of metamorphism. This set up is traversed by dolerite intrusive. Further the entire association is overlain by the pakhal supergroup consisting of meta sediments. The Gondwana supergroup constituted by sediments rests over the other units unconformably. GEOMORPHOLOGY MAP Geometrography is defined as part of geomorphology dealing with the description of earth’s surface features/land forms. The link age between the physiographic units and geomorphic units are necessary to relate the land form and soils. Geomorphology map is prepared by visual interpretation of high resolution satellite imagery with the help pf survey of India Topographic maps and ground truth lithology, drainage and contour maps are considered while preparing the geomorphology map. The earth’s surface can be classified in to different geomorphic units /land forms based on their physio graphic expression origin, material content and climatic conditions etc. technical guidelines of national remote sensing center are taken into consideration in the classification of geomorphic units. In the study area the fallowing eight geomorphic units are delineated from the satellite imagery geomorphology map showing figure 3.7 PPS: Pedi plain shallow weathered VFS: valley fill shallow PD: Pediment PIC: Pediment -inselberg Complex I: Inselberg DR: Dyke Ridge RH: Residual Hill DH: Denudation Hill Geomorphology map used for the preparation of ground water prospects map.

Water requirement and Resources: An approximate 10 KLD of water is required for the proposed project which will be utilized for the water sprinkling on haulage roads and domestic purpose viz. Housing colony, Greenery and livestock. As such both surface and ground water resources have been assessed for computing the resources. Entire water requirement will be net from the ground water for which potential bore holes will be drilled. Hydrogeology: The main factors that play a vital role in the occurrence and moment of ground water are climate, distribution and intensity of rain fall, Topography, Geological setting, Nature and thick ness of weathered mantle, geometry of work plains like joints, fractures fissures, bedding plants etc. recharge conditions, transmissivity nature and storage conditions of the aquifers etc. The ground water in the study are is confined to the weathered and fractured zone and at places in the contact zones and occurs under confined two semi confined conditions. About eight borewells were inventoried. The depth to water level observed in these wells is 9 – 12 m BGL. The reported yields 50-100 LPM. The water is being Bailed with a hand pump and water being used for drinking and domestic purposes. The field data was collected during May 2013. There was no agriculture dug wells and mainly rain feed crops are sown with miner extend depending upon tank irrigation. Ground water exploitation in and around the project site is found to be moderate and mostly utilized to domestic purpose. Most general crops grown in the area are paddy, Ground nut, Citrus plantation, Vegetables. The ground water resource estimation in and around the project area were estimate based on the recommendations of the GEC methodology.

I) Recharge from rain fall infiltration method = Geographical area X Normal rain fall X infiltration factor. 31,400.000 X 950 X 0.03 =0.894 MCM

II) Ground water drafts: Ground water drafts refers to the quantity of ground water that is being withdrawn from the aquifer which is approximately 0.4 MCM for all purposes

III) Balance ground water potential is 0.494 MCM IV) Stage of development = (Draft / Net annual GW availability) X 100 = 44.74% V) Category = Safe

The use of ground d water is very minimal and hence can be exploited safely

Ground water potential map The Ground water potential map is prepared based on the analysis of various themes such as geomorphology, land use /land cover, line ament, intersection points, drainage pattern, lithological evidences by using converging evidence concept, beside the collateral data obtained from state ground water board with necessary field checks. The Ground water potential map revels the alliable quantum of ground water. This map is delineated in to as per CPCB guidelines. In the study area high grade, moderate and low ground water potential zones are observed. In the high-grade zone, the expected yield range are 100 LPM to 200 LPM. In the moderate zone the expected the yield ranges are 20 PM to 50 LPM. <20 LPM of yield indicates poor zone >200 LPM of yield indicate excellent zone. The ground water potential map of study area has showing in figure 3.8. Conclusions:

1. The normal rain fall of the area is 950mm 2. The sustainable water resources both surface and ground water are estimated at 0.894 MCM 3. Use of ground water for agriculture found to be moderate and mostly utilized for domestic uses

and cattle. 4. The mining lease area can be operated with ground water resources with the expected regular

monsoon and proposed recharge stricture for augmenting the replenish Abule water source as such will not affect the water regimen of the area.

Recommendations

1. The minimum 10 KLD can be safely pumped from the borewells 2. Ground water to be exploited to meet the domestic requirements of the plant housing green

belt and livestock with ground geophysical surveys and hydrogeological exploration. 3. It is proposed to take up rain water harvesting structures and artificial recharge structure such

as surface storage ponds check dams, gully plugs etc. at suitable sites to augment the ground water depletion.

4. Afforestation in surrounding areas to be taken up.

abler tete waTh a. etudy are sin th ~n the buffer zone is at a depth of 40m below the general ground

level and hence the opencast mining operations will not intersect groundwater table and there will not

be any ground water release due to opencast mining till ultimate pit limit depth in the quarries. Quality

of ground water in the bore-wells in core zone and buffer zone is within the drinking water desirable

standards (IS 10500). Mining and allied activities shall have no direct or indirect impacts on these

natural nalahs and streams.

Water Consumption &Wastewater Generation

S. No Purpose Quantity (KLD)

1. Dust Suppression purpose 8.0

2. Domestic purpose 1.0

3. Greenbelt purpose 1.0

4. Total 10.0

Wastewater Generation

About 0.5 KLD of domestic effluent is generating from this mine an this is sent to septic tank followed

by soak pit.

Surface water environment

No soluble waste is generated from the mine. Storm water from mining and waste dump areas is the

major source of pollution of surface water bodies with excess silt, turbid particles (colloidal matter). The

mine will not seriously affect the flow of storm water, especially much of the rain water rapidly infiltrates

through the rock fissures. Excess storm water requires effective management plan which includes

collection of storm water through garland drains and contour trenches before being discharged into

natural nallahs. The proposed mining operations shall not interfere with the natural nallahs and streams

present in the Core and Buffer zones. No change of natural stream course is anticipated. Due to the

underground mining operations only, mine seepage water and domestic wastewater is generated.

3.3.3 PROPOSED MITIGATING MEASURES

Raw water treatment: It is planned to withdraw 10 cu.m/day of water from ground water resources for

dust suppression, green belt development, drinking and sanitation

Waste water: The mine as such would not produce any significant quantity of waste water on a

continuous basis except nominal amount of sanitary waste water in the range of 0.5 cu. m/day. It is

proposed to treat this water in a septic tank. The treated water would be used for greenbelt development

and the sludge (removed every 3 years) used as manure for the vegetation.

P a g e | 47

Silt water control: There shall not be any significant silt as there shall be very less amount of solid

waste generated. During the monsoon period, run-offs from the overburden dump and top soil dump

would be checked by garland drains and retaining wall. The retaining walls would be made from

boulders by cement pointing. In addition, the overburden dump would have garland' drains all around

for each terrace of adequate size so that velocity is appreciably reduced to enhance the settling of the

fine particulate. Contour trenches shall be dug within the core zone to assist in ground water recharge

with standard classification of soils indicate:

• All soils under study are neutral in terms of pH.

• Soils collected in buffer zone are deficient in nutrient content.

• Green belt development in mining area needs proper amendments with regular addition of

nutrients (NPK) and organic fertilizer.

DESCRIPTION OF LAND USE /LAND COVER CLASSES IN THE STUDY AREA

INTRODUCTION

Land Use (LU) refers to man's activities and various uses, which are carried on land. Land Cover (LC)

refers to natural vegetation, water bodies, rock / soil, artificial cover and others resulting due to land

transformation. Although land use is generally inferred based on the cover, yet both the terms land use

and land cover are closely related and interchangeable.

Information on the rate and kind of change in the use of land resources is essential to the proper

planning, management and regulation of the use of such resources. Knowledge about the existing land

use and trends of change is essential if the nation is to tackle the problems associated with the

Haphazard and uncontrolled growth. A systematic framework is needed for updating' the land use and

land cover maps that will be timely, relatively inexpensive and appropriate for different needs at both

national and state levels. The rapidly developing technology of remote sensing offers an efficient and

timely approach to the mapping and collection of basic land use and land cover data over large area.

The satellite imageries are potentially more amenable to digital processing because the remote sensor

output can be obtained in digital format. Land use data are needed in the analysis of environmental

processes and problems that must be understood if living conditions and standards are to be improved

from or maintained at current levels.

It is required to carry out the land use I land cover study for the project study area (10 km radius) to

obtain the necessary environmental clearances from statutory authorities. The objective of the study is

to carryout land use I land cover study for the proposed project. The LU I LC study is carried out using

the Satellite Imageries (IRS P6 LlSS IV MX) in addition to Survey of India Toposheets. Appropriate

guidelines are followed while preparing the LU I LC map for the project study area.

• The current land use type of project site is already surrounding areas stone quarry area. This

land will be converted in to mining area.

• As per land break up single crop land and double crop lands are the major land use type

covering the study area. Crop land and mining area are influencing factors to the environment.

• No Major industries are located in the study area

• Nearest settlement is Aitapalli village. Nearest habitation is Nandagiri

• No railway line is observed within the study area of 10 km

• Kakatiya canal is the main irrigation source is observed within the study area of 10 km radius.

• There is no reserved forest within the study area or 10 km radius.

• Paddy, Cotton, Jowar rice and Pulses are major irrigation crops categorized as single crop.

Agriculture and irrigation

The mine lease area is surrounded by barren. land. The availability of agriculture land within a radius

of 1 km from the mine is less. However, agriculture is the main occupation of the surrounding villages.

Agriculture in the buffer zone mainly depends on the canal and borewells. The major crops grown in

this area are Jowar, Maize, Red gram, Sunflower and Cotton. Chrysanthemum and Mary gold flowers

are also grown as commercial crops. Paddy is also cultivated near the river during the Khariff season.

All the villages are provided with bore wells/dug wells and tube wells to cater to the agricultural needs.

There are two cropping seasons namely Khariff from June to September and Rabi from November to

March. There is however, a little variation in these periods with regards to Paddy, which is cultivated in

both seasons. The crop yield during Rabi is generally moderate

3.4.2 ANTICIPATED IMPACTS ONLAND

The mining area is hilly and undulating land. The waste filled dump sites shall be terraced with overall

slope in the direction of natural ground level slope. In most cases, the overall slope of back filled surface

shall merge with natural slope. The topographical impact will be mainly one of colour contrast between

then mined rock surfaces and surrounding vegetation (shrubs and grasses). However, the

topographical impact will remain localized, given that the site is contained and the change in topography

will not have appreciable impact on drainage and aesthetics.

The top soil in the mining area is scanty. Whatever is available will have to be excavated during the

development of the mine pits. Most of this soil is rocky in nature and will get mixed with the over burden.

Temporary storage of top soil over burden may cause some loss of nutrients and this cannot be avoided.

The top soil will be subjected to water borne erosion during rainy season from reclamation areas when

in unconsolidated state. A combination of diversion ditches and garland drains will be constructed to

minimize soil loss. A large amount of soil loss can be arrested in contour trenches, which will be

collected and put back to the reclamation areas. Since the mining area is contained to only 29.00 Ha.,

the effect on the land environment will be negligible. There shall be no leachate from the lease area.

There shall be soil erosion of the loose soil of waste dumps which shall be contained. The adverse

effect of the mining activity on the bio diversity shall be mitigated by employing proper mitigating

measures.

3.4.3 PROPOSED MITIGATING MEASURES

The land management plays an important role in reducing the adverse impacts caused by surface

mining operation. Land management is required in the key areas like land use scheme within the ML

area, calendar plan, mine bench advancement to arrest indiscriminate degradation of landform, top soil

preservation, overburden management, soil erosion control and the restoration of the mine pits. On

each of these prime areas of land management, the following schemes are proposed.


Telangana State.


P a g e | 57

Land use

The project covers a total ML area of 29.00 hectares of Government Revenue land. The Quarry lease

area is a small mound / plain area and is fit for quarrying. The adjacent area is also of similar type.

Hence suitable for mining purpose only. However, in the plains the land use pattern is mainly agriculture.

Dry crops are grown.

Calendar Plan

A mining plan is prepared for the lease period of twenty years which has been approved by the

department of Mines and geology. The calendar plan for such surface mining operation depicts the

excavation planning of overburden as against excavation of Granite in each year up to a specific period

of mining. It ensures the landform change in a planned manner, one of the essential tools for land

management. The development of the mine would be in phases spread over a period of 5 to 20 years.

Overburden dump management:

Removal of weathered rock and the rock waste is the only solid waste that will be generated from this

mine. It will be removed and will be dumped along the northern portion of the lease where already a

dump exists, which will be simultaneously used during the mine reclamation. From the solid waste that

is generated during the primary mining activity blocks that are useful for cutting tiles and slabs will be

separated, the remaining material will be used as road metal or building material. All the care will be

taken to minimize the waste generation at the source. From the waste generated, blocks of 2' X 2' X 2'

are separated and kept at the dump site for subsequent dressing and will be used for the domestic

consumption, the waste of various dimensions less than 2' X 2' X 2' will be used for back filling the

quarry areas. It is also supplied to crushing plants and is used as road metal. The left-out waste will be

used for back filling the quarry, which will be covered with soil added with soil conditioners and mine

will be reforested. For further stability of the dump and improved aesthetics, the slopes of the

overburden would be progressively revegetated with local' or introduced trees, shrubs and grasses.

Top soil preserved would be spread over the slopes of the dump for vegetation growth. In order to

stabilize the slopes and to prevent slope failures, Geo textile mats shall be laid over the waste material.

This mat shall cover the dump area and reduces, soil erosion thereby enhancing the growth of

vegetation.

Mine roads

Roads for haulage and access to different locations would be laid as per the statutory regulations

stipulated in the Metalliferous Mines Regulations, 1961, Some of the basic features of laying the haul

roads at the mine site as required from environmental and safety angle should cover the following:

• The road layout would be generally followed as per scheme shown in mine general layout. The

main haul road and feeder roads would be generally of 12 m wide keeping provisions for

roadside plantation.

• The corners and bends would be made in such a way as to offer the vehicle operator, a clear

visibility of at least 30 m along the road.

The alignment of haul roads and feeder roads may require alteration with the progress of mining work.

Storage and preservation of top Soil:

The soil in the mine can be described as medium textured, rocky white & reddish brown in color. The

soil cover of the miner able areas with low nutrient level is devoid of any vegetation cover. While

scrapping the top soil cover of the miner able area by a bulldozer prior to removal of overburden layer,

the soil removed shall be stored and preserved in the earmarked dump areas for future use. The top

soil will be stored separately in the area earmarked for waste dumps to be located at the southern

portion of the lease area. It may be noted that once the in-situ soil is disturbed by scrapping, soil particles

lose their coherence and tendency to stick to one another. The soil therefore needs to be graded and


Telangana State.


P a g e | 58

compacted at the dump site. The soil quality may be upgraded by adding suitable amendments and

organic manure to improve the nutrient levels. The soil stockpile height shall preferably be restricted to

3m and the surface vegetated with fast growing shrubs, creepers or grasses to prevent erosion and

loss of nutrients. Topsoil thus stored and preserved would be utilized as early as possible by spreading

the same over the overburden dump and during mine pit rehabilitation for the purpose of vegetation

growth.

Soil erosion control:

The soil erosion is expected to be very less due to the lease area being plain and undulating

The overburden and topsoil dumps would be provided with check dam / bund wall to prevent carryover

of soil particles / silt to the drainage channels on the slopes during monsoon period. Typical proposed

check dams (3 no.) and retaining wall at dump sites are presented in Diagram Nos. 3.12 and 3.13

Fig: 3.12 A Typical proposed check Dam Across the Nallah To Arrest Silt carry Over

Fig: 3.13 A Typical Proposed Retaining wall at D/S of Dump Site

Location restoration:

During the course of mining, the original land form would get disturbed. In the initial stages of the mining

operation, concomitant reclamation of the land may not be possible due to following operational

reasons:


Telangana State.


P a g e | 59

• Simultaneous opening of different benches at different levels for achieving the desired tonnage

and grade of R.O.M.

• Irregular and heterogeneous nature of mineralization.

• Unfavorable topography limiting the total backfilling of the pits with overburden.

In consideration of the above constraints, it would be preferable to take up the backfilling of the mined-

out block after exploitation of the mineral. The restoration of the degraded land would cover backfilling

and terracing with the overburden / wastes and surfacing the same with top soil. Fast growing trees and

other native shrubs would be planted to stabilise the reclaimed land and prevent wind erosion of solid

particles. It is preferable to sow seeds of eco-friendly weeds which grow even in adverse conditions.

These weeds stabilise the ground and enhance the growth of the native species of trees that shall be

planted over the dumps.

Post-mining land restoration is basically mine rehabilitation. It is estimated that at the end of the total

exploitation of the deposit, about 30 to 40 per cent of mine leasehold land would be degraded. It would

be necessary to plan and execute the post-mining restoration with an objective to recoup the lost

vegetation so that the local communities are benefited to the extent practicable. The original land form

should be brought back by backfilling and terracing with the overburden I waste material and

subsequent vegetation of the restored land. While reclaiming the mined-out area, the original land form

cannot be fully restored. There would be some left out pits and depressions of varying depth which can

serve as a recharge pits by the impounding rain water. This would be beneficial in two aspects, namely

(i) it may recharge the spring table by seepage of water through cracks and joints and (ii) the impounded

water reservoir can be utilised for development of afforestation.

3.5 Biological Environment

3.5.1 Base line Status

Quantitative Survey of plant community

The structure and composition of plant community depends on a wide. variety of abiotic and biotic

factors such as soil, climate including temperature, rainfall etc. A complete structure of the community

could be obtained by studying the terrestrial flora of that particular area. Since it is prone to be disturbed

by the mining activity, it is necessary to review or analyze their establishment. Hence the present study

was carried out meticulously covering a distance of 10 Sq.km, adopting the standard methodology.

Vegetation in Plains and core Zone

The core zone has a scanty growth of shrubs and bushes. This is due to the fact that the area is rocky

and does not support plant growth. However, the species like Prossopis juliflora, Cassia auriculata,

Calotropis procera, Lantana camara are commonly observed. In the plain area. of the buffer zone the

natural vegetation is composed of common. avenue trees, fruit trees, agro forest species and other

introduced exotic species A list of trees, shrubs and perennial climbers found in the buffer zone are

given in Annexure- E

Fauna

There are no biosphere reserves or national parks or wildlife sanctuaries or other protected or

ecologically sensitive areas within a radius of 10 Km from the Mine Lease Area (MLA). The open scrub

forests around the MLA are not a home for any rare or endangered or endemic or threatened (REET)

species. A list of vertebrate species either spotted or reported from the areas around the MLA is given

in Annexure-F

3.5.2 IMPACT ON BIOLOGICAL ENVIRONMENT (Flora & Fauna)

The mine lease area consists of rocky terrain with very less vegetation. Even this scanty vegetation will

disappear in the area due to various mining operations like dumping of waste rock, over burden, road

formations and infrastructural facilities. Mining induced dust pollution is a major threat to vegetation in ML

area, which impairs photosynthesis. However, the loss will be more than compensated by nutrient

availability through dust fall. Further, the deleterious impacts of dust shall be limited to the dry post monsoon

period when most plants stop growing due to moisture stress. Any further less carbon sequestration a

productivity will be adequately compensated by the development of green belt.

Mining activity may be highly harmful to the soil flora and fauna. But the inhabitations of the soil are mostly

seasonal and highly resilient. As such they can come back with the onset of suitable conditions. The MLA

is not a home or feeding or breeding ground for any of the REET species. As such the proposed mining

activity will not result in any net loss of biological species. Much of the fauna may be scared away initially

due to blasting operations but they get easily adopted to the changing environmental with appropriate

response. There are no endangered, threatened, rare of protected species in the study area. As, such the

anticipated mining impacts may be temporary and reversible. Further the direct impacts shall be limited to

the mine pit and the OBD.As the area is not ecologically sensitive and there are no REET species, the

proposed mining activity will not lead to any “net loss “of species.

3.5.3 PROPOSED MITIGATION MESURES

The environment management plan to mitigate the adverse impacts on Flora and Fauna of the core zone

comprises mainly of afforestation with the dominant native species. The development of green belt along

the boundary of the mine brings an aesthetics look. The fauna which was scared away due to mining

activities shall slowly restore. The restoration of fauna shall be accelerated by the introduction of few native

species also. The pit shall be fenced to prevent inadvertent entry of the animals. the working of the mine

is restricted to daytime only. A composite plan of greenbelt development within in the MLA will be

implemented. The plan is prepared taking in to consideration the growth of diverse species to be planted

should be compatible with the local site conditions and provide good habitation for avifauna. Nitrogen fixing

leguminous species are also included. The species selection takes in to account various other purpose like

erosion control, economic value, medical value as well as aesthetics. For carrying out this green belt

development programme within the acquired area.it may be necessary to arrange procurement of good

quality soil from other sources apart from condition of the existing soil cover with lime and other nutrients.

OCCUPATIONAL STRUCTURE

The occupational structure of residents in the study area is studied with refence to main workers, marginal

workers and non-workers. The main workers include 10 categories of workers defined by the census

Department consisting of cultivators., agriculture labors, those engaged in live-stock, forestry, fishing,

mining and quarrying manufacturing, processing and repairs in household industry: and other than

household industry, construction trade and commerce, transport and communication other services.

The marginal workers are those workers engaged in some work for a period of less than six month during

the reference year prior to the census survey. The non-workers include those engaged in unpaid household

duties, students, retired persons, dependents, beggars, vagrants etc. institutional inmates or all other non-

workers who do not fall under the above categories.

As per 2001 census records altogether the main workers work out to be 50.56% of the total population.

The main workers and marginal workers constitute to 50.56% and 7.57% of the total population

respectively. The distribution of workers by occupation indicates that the workers are the predominant

population.

Disease

Diarrhea, Malaria, Gastro-enteritis, eye and skin diseases are generally prevalent. Leprosy appears to be

comparatively uncommon.

Economic conditions

In general, the economic condition of the people in the study area can be described to be marginally below

the poverty line. Agricultural produce being not adequate for a comfortable life, majority of the villagers in

the study area has income levels below par. Most of the population is involved in petty trade related works.

Aesthetics

The study area is small and forms part of Pegadapally Mandal. The study area climate is temperate to hot

summers. Kakatiya canal and bore wells are source of irrigation tough the area receives good rain fall.

3.6.2 IMPACT ON SOCIO-ECONOMIC ENVIORMENT

Operation of mining and associated activates will result in some socioeconomic impacts of direct and

indirect in nature.

Impact on human settlements

The mine is an existing project. There is no human displacement within the mine lease area. The project

has no impact on human settlement.

Population growth

The project will have little impact on population growth due to immigration of people for employment. Since

the project is an ongoing project, no migration of labor is envisaged

Impact on literacy and educational facilities

The literacy level of the project area (buffer Zone) is likely to increase as there will be in flux of educated

people taking up jobs in the mining. Life style may change.


State.


P a g e | 66

Impact on civic amenities

Network of roads, telephone facilities, education facilities and health care facilities may be improved due to

project. A higher demand for food facilities may appear in buffer Zone.

Impact on employment

The mine shall employ 70 people. In addition to the employment in the mine additional people shall also

get employment due to allied activates like transport and related business. In all, the mine shall generate

an additional employment to around 60 people.

Impact on economic aspects

Per capita income shall increase slightly due to direct and indirect employment.

Impact on industrial establishments

Small scale industries and small business centers may likely to come up in the vicinity of the project.

3.6.3 PROPOSED MITIGAING MEASEURES

Socio-economic development

The development of the proposed project will also take into account certain social obligations involving

economic and educational upliftment of the local population. This may be in the form of extending their

cooperation to the State Government and the dedicated NOs in ventures such as providing educational

aids to the schools, opening up of primary health centers, providing financial assistance for setting up agro-

based cottage industries, improving sanitary conditions in selected villages, etc. The main objective of this

development programmer is to make the project, society friendly asper of sustainable development

measures.

Health and safety

Legislation in India Mines requires care for occupational health care and safety of mine workers as an

integral part of the mine production management.

Occupational health care:

The mine workers are generally prone to occupational health problems relating to dust and noise. In mining

operations, the workers may get affected with lung diseases resembling pneumoconiosis due to presence

of dust, when exposed for a prolonged period to mineral dust particles of size less than 5 microns,

particularly in the range of 1-2 microns. Indian Mine Regulations amended in 1988-89 lay down norms for

safe limits of free silica levels in respirable dust in the work zone it would, therefore, be necessary to keep

the work zone environment free form dust levels would be provided with dust masks.

The major occupational health problems relating to noise range from physiological and psychological

problems resulting in loss of concentration to permanent impairment of hearing ability. To prevent these

noises related occupational health problems, the necessary control measures as outlined earlier would be

helpful


State.


P a g e | 67

Medical facilities

For the proposed mining operation, adequate medical surveillance will be carried out, covering routine

check-up and treatment of affected workers as required. The medical staff will be familiar with the latest

diagnostic tools for occupational diseases. First aid medical kits would be made available at the work spots.

Drinking water

Drinking water would be supplied in rest shelters, canteens, workshops, etc. The mines rules specify a

minimum per capita requirement of 2 liters per day. Drinking water taps shall not be within 6 m of any

washing place, urinal or latrines as per mine regulations. The management has promised to spend an

amount of Rs.50,000/- per annum, for the development of drinking water facilities in the nearby villages.

Sanitation facility

Water flushed latrines and urinals would be provided at conveniently accessible points at the scale of one

seat for every 50 (or part) persons, with the associated facilities for disinfection.

CHAPTER IV

4.0 DISASTER MANAGEMENT PLAN

It is presumed that the proposed mining process would be designed and engineered with all possible safety

measures and standard code of practices. In spite of this, there may be some design deficiency or due to

operation and maintenance faults which may lead to accidental events causing damage to life and property.

This chapter presents an overview of environmental risk associated with various mining operations,

suggested remedial measures and an outline of the emergency preparedness plan.

4.1 Risk assessment

The objective of environmental risk assessment is governed by the following, which excludes natural

calamities.

a. To identify the potential hazardous area so that necessary design safety measures can be adopted

to minimize the probability of accidental events.

b. To identify the potential area of environmental disaster, which can be prevented by proper design

of the installations and their control operations.

c. To manage emergency situation or a disastrous event, if any from the mining operation

4.2 Identification of Hazards

During the proposed operation of the open cast mine, the following risks have been expected

1. Filling Up the mine pit due to excessive rains

2. Failure of slope in the pit

3. Failure of slope of external dump

4. Fly Rock fragment from blasting Operations

5. Accidents of heavy machinery

6. Surface fire (Electrical and Oil)

7. Possible Danger due to storage of Explosives

4.2.1 Filling Up the mine pit due to excessive rains

Filling up the mine pit due to excessive rains in the worked-out area is remote possibility. Normally

there will be sufficient warning time before such an incident takes place. Harming equipment and

human life. However, as a precautionary measure, interceptor ditches along the outer boundary of

the pit area constructed to control inflow of runoff into the mine pits. Water that collects in the mine

pit from rainfall will be pumped out from the pits, using centrifugal pumps.

4.2.2 Failure of slope in the pit

In order to allay dangers due to open cast slope failure, slope stability estimations have been made

of the existing quarries after determining various physical parameters of the existing quarries after

determining various physical parameters of the ground mass like uniaxial compressive strength

triaxial comprehensive strength, cohesion, angle of friction, specific gravity of the rock, water

pressure etc. Besides, all the discontinues have been plotted in stereo plots, which indicate that

there is no chance of any planer failure or wedge failure Even then factor of safety has been


State.


P a g e | 69

defeminized against overall slope failure as well as against individual bench slope by circular

failure, planer failure, wedge failure, Besides determining factors of safety the slopes are monitored

at regular intervals to check for any possible failure. The well slopes are monitored at regular

intervals to check the for any possible failure. The well-developed drainage system over the lease

area ensures that storm water does not accumulate in the lease area and therefore hydrostatic

pressure remains at a low level.

Thus, all types of measurements and inspections will be carried out. The mine has been designed based

on the above considerations with sufficient safety margins to eliminate any chances of slope failure in the

pit.

4.2.3 Failure of Slope of external dump

The slopes of external dumps have been initially planned at the angle of repose of dump material. However,

as the edge attain final position, the slopes will be terraced and proper vegetation will be laid which will

cause lowering of the slopes as well as binding of the soil, preventing any slope of failure.

4.2.4 Fly rock fragments and vibrations due to blasting

Trail blasting results from nearby mines have been used to arrive at the field empirical equations based on

which the charge per delay has been regulated to protect the nearby structures. All precautions related to

control of fly rock will be taken during the blasting operations. Safety zone of 500m as per statute shall

maintained. The nearest habitation is too far to be affected by fly rock.

4.2.5 Accidents of heavy machinery

Most of the accidents during transfer of dumpers, trucks and other vehicles are often attributed to

mechanical failure, in which the factor of human errors cannot be ruled out. The subject mine and the

machinery is very less and hence the cause of accidents.

4.2.6 Surface fire

Spillage OF HSD and resultant fire constitutes a potential risk. The quantity of the maximum oil, which can

spill, is not much and can be easily controlled. Sufficient numbers of portable fire extinguishers has been

provided at tragic locations to take care of eventually.

As soon as any fire is reported the shift-in-charge shall assume the function of disaster controller. In case

of serious fire and depending on the gravity of the situation. The Mines Manager may be summoned to

assume charge. Personal trained in dealing with fires will be summoned. Meanwhile the hospital will be

informed to handle causalities. The fire area will be cordoned off till the fire is fully extinguished and remain

so until all wrecked and debris cleared away.

4.2.7. Danger due to storage of explosives

An explosives magazine exits in the mine. Adequate safety zone has been provided as per statutory

requirements while locating the magazine. The magazine should have to be constructed as per plan

approved by Departments of Explosives. The following have been considered in the design of the

magazine.

CHAPTER V ENVIRONMENTAL MANAGEMENT PLAN

5.0 INTRODUCTION

The mining development in the study area needs to intertwined with judicious utilization of natural resources

within the limits of permissible assimilative capacity. The assimilative with judicious utilization of natural

resources within the limits of permissible assimilative capacity. The assimilative capacity of the study area

is the maximum amount of pollution load that can be discharged in the environment without affecting the

designated use and is governed by dilution, dispersion and removal due to natural physio-chemical and

biological processes. The Environment Management Plan (EMP) is required to ensure sustainable

development in the study area.

This Chapter the proposed measures required for meeting the prevailing statutory Requirement of gaseous

emission, wastewater discharge characteristics, noise levels etc. For environmental management purpose

in connection with the mining and mining related activities in the study area. This section discusses the

management plan for mitigation/abatement impacts and enhancement of beneficial impacts due to mining.

The Environmental Management Plan(EMP)has been designed within the frame work of various Indian

legislative and regulatory requirements on environmental and socio-economic aspects.

Environmental Management Plan giving the environmental protection measures at mine to meet the

stipulated norms of IBM/ MoEF are as detailed under.

5.1 AIR POLLUTION CONTROL MEASURES

The present ambient air quality measurements in the mine area are well within the limits. Due to the

proposed production of 9600 Cu.m/year of colour granite, there will be marginal increase in dust

concentrations.

Mitigative measures suggested for air pollution control are based on the baseline ambient air quality

monitoring data. From the point of view of maintenance of an acceptable ambient air quality region, it is

desirable that air quality should be monitored on a regular basis to check it vis-à-vis the standards

prescribed by CPCB and in cases of non-compliance appropriate mitigative measures shall be adopted.

The following dust prone area are identified for adopting proper control measures in the mine area.

I. Drilling & Blasting

II. Excavation

III. Transportation

The environmental control measures which will be implemented to control the fugitive dust released from

the proposed production are given below.

• Wet drilling system & Dust proof

• Option Wire Saw Cutting (using water reduces dust)


State.


P a g e | 75

• Use of sharp drill bits for drilling holes. The charge concentration of the explosives will be between

10-40- grams per linear meter.

• Water sprinkling arrangements such as specially fabricated tankers mounted on tipper are

deployed at mine site to control the fugitive dust generation from the haulage roads.

• Regular grading of haul roads and service roads to clear accumulation of loose material

• The blasted blocks(temporary) are wetted by spraying water

• Avoiding blasting during high windy periods, night times and temperature inversion periods

• Excavation operations are suspended during periods of very strong winds

• Massive afforestation for control of dust

• Spraying of water on sub grade stacks

• The vehicles and machinery are kept in well-maintained condition so that emission of fugitive

constituents is minimized

• Plantation of wide leaf trees, creepers, tall grass around working pit, along roads will help suppress

dust.

• Tall trees with an average height of 5m will be developed all along the boundary of the lease area

to minimize the dispersion of the dust from the mining

• Periodical monitoring of air quality to take steps to control the pollutants.

Vehicular emission control(VEC):

Vehicular emission from diesel operated transport equipment can be contained, by avoiding idle running

and overloading of the engine. In addition, the engines shall be periodically serviced to ensure proper tuning

and exhaust gases monitored on a regular basis to check smoke and CO levels.

5.1.1. OCCUPATIONAL HEALTH & SAFETY MEASURES

All the precautions would be adopted to prevent dust generation at the site and to be dispersed into the

outer environment, however, for the safety of workers at site, engaged at strategic location/dust generation

points like loading and unloading points, etc., dust masks would be provided. Dust masks would prevent

inhalation of RSPM thereby reducing the risk of lung diseases and other respiratory disorders. Regular

health monitoring of workers will be carried out.

5.2 NOISE POLLUTION CONTROL

The ambient noise level monitoring is carried out in and around the proposed mine shows that ambient

noise levels are well within the stipulated limits of CPCB.

Noise generation may be for an instant, intermittent or for continuous periods, with low to high decibels.

Periodic inspection and checks of the riskprone areas and equipment’s have to be conducted.

To Control noise pollution during the proposed mining operations following steps will be practiced

• The noise generated by the machinery will be reduced by proper lubrication of the machinery and

equipment

• The workers employed should be provided with personal hearing protection equipment, with

earmuffs and earplugs, combined, as a protection from the high noise level generated at the plant

site


State.


P a g e | 76

• The provision of green barrier along the boundary will further reduce the propagation of noise level

generated

• Limiting time exposure of workers to excessive noise

• Carrying out blasting only during daytime and avoiding the same on cloudy days and when strong

wind blows across

• Speed of trucks entering or leaving the mine is limited to moderate speed of 25 kmph to prevent

undue noise from empty tippers

5.3 Control of Ground vibrations

The villagers are located more than 1.1kms from the site and the waves are not likely to travel up to this

distance & the ground vibration expected in these villages are very negligible. However, the lessee will take

up ground vibration studies through a reputed. Concern after the commencement of MINING operation &

take preventive measure necessary to reduce the effect of ground vibration

The lessee will also adopt control blasting practice by using the fallowing measures

• During blasting, proper blast pattern should be adopted. The latest technology delay blasting should

be adopted to reduce the impact on the ground vibration and noise generation during blasting

operations.

• Shock tube imitation system with sequential blasting should be adopted

• Blasting should be done in only one bench at a time.

• Charge weights per delay should be properly adopted so that the peak particle. Velocity will be

maintained as per the DGMS requirement.

All the above-mentioned points will be taken care, while planning and conducting blasts

5.3.1 Safety in Blasting

Care should be taken to evacuate the mining area completely at time of blasting operations. The blasting

team should be equipped with all personal safety and precautionary measure. The following safety

measures will be given attention while conducting the blasting operations.

• A blasting SIREN should be used at time of blasting for audio signal

• Before blasting and after blasting red & green flags should be displayed as visual signals.

• Warning notice boards indicating the time of blasting and NOT TO TRESPASS are displayed

prominently.

5.4 Water Pollution Control Measures

Raw Water Treatment: It is planned to withdraw 10 Cu.m/day of water from ground water resources for

dust suppression green belt development, drinking and sanitation. For drinking water, Chlorination shall be

done along with an UV and water filter for drinking.

Waste water: The mine as such would produce mine seepage water during underground mining operations

and nominal amount of sanitary and canteen waste water in the range of 0.5 to 1 CU.m/day. It is proposed

to treat this water in a septic tank. the mine seepage water would be used for dust suppression and green

belt purpose in ML area. The domestic effluent is sent to septic tank fallowed by soak pit.


State.


P a g e | 77

Silt water control:

There shall not be any significant silt as there shall be very less amount of solid waste generated. During

the monsoon period, run-offs from the overburden dump and top soil dump would be checked by garland

drains and retaining wall. The retaining walls would be made from boulders by cement pointing. In addition,

the overburden dump would have garland drains all around for each terrace of adequate size so that the

velocity is appreciably reduced to enhance the settling of the fine particulate. Colour trenches shall be dug

within the core zone to assist in ground water recharge.

5.5 Land Restoration and Pollution Control

Mining will be carried out in accordance with rule 32 of GCDR,1999 Obliging this rule, restoration,

reclamation and rehabilitation of the lands affected by mining will be done by back filling, Soil amelioration

and afforestation. Is will be taken up on need basis before the conclusion of mining operations. The back

filling of the mine starts from the eastern end and proceeds towards western side. Reclamation of the

effected land includes back filling, drainage development, spreading and fertilizing the soil (Soil

amelioration), leveling and vegetation etc. Care will be taken to implement the said factors.

Land Use

The projects cover a total ML area of 29.00 ha of Government Revenue land The ML area is principally

degraded land and has sporadic patches of very little shrub vegetal cover in the hill slopes. The core zone

landscape can be improved by tree plantation, shrub growth etc., Which are outlined separately under eco-

restoration.

Calendar Plan

A mining plan is prepared for the lease period of twenty years which has to be approved by the department

of Mines & Geology. The colander plan for such surface mining operation depicts the excavation planning

of overburden as against excavation of granite blocks in each year up to a specific period of mining. It

ensures the landform change in a planned manner. One of the essential tools for land management. The

development of the mine would be in phases spread over a period of 5 to 20 years

Overburden dump management

It is estimated that 60 primary blocks of 4mX3mX2m can be produced in a year waste of 7344 Cu.m will be

anticipated per year.

From the waste generated blocks of 2’X2’X2’ are separated and kept at the dump site for subsequent

dressing and will be used for domestic consumption. The waste of various dimensions less than 2’X2’X2’

will be used for back filling the quarry areas. It is also supplied for crushing plants and is used as road

metal. Then left out waste soil conditioners and mine will be reforested.

Stabilization of Dumps:

The dumps are mainly constituted of quarry waste with very little soil .It will be afforested properly to stabilize

the dumps and preserve the soil characters The sites are almost barren and non-promising zones .no

special ground preparation is envisaged .The overburden would be loaded on rale –dump tractors by front-

end loaders for transportation to dump areas .Formation of the staking of the overburden would be initiated


State.


P a g e | 78

by dumping of overburden materials on the ground all along the outer periphery of the demarcated area.

Once this is completed, further quantity of waste would be dumped inside the vacant space of the perimeter

stacking. The process would continue till the entire ground area is filled in after which the stack is dressed

and leveled. The stock formation process will continue till the final height is reached. For further stability of

the dump and improved aesthetics, the slope of the overburden would be progressively re-vegetated with

local or introduced trees, shrubs and grasses. Top soil preserved would be spread over the slopes of the

dump for vegetation growth. In order to stabilize the slopes and to prevent the slope failures, Geo textiles

mats shall be laid over the waste material. This mat shall cover the dump area and reduces the soil erosion

thereby enhancing growth of the vegetation.

Mine roads

Roads for haulage and access to different locations would be laid as per the statutory regulations stipulated

in the metal ferrous mine regulations.1961. Some of the basic features of laying the haul roads at the mine

site as required from environmental and safety angle should cover the following.

• The road layout would be generally followed as per scheme shown in mine general layout. The

main haul road and feeder roads would be generally of 12m wide keeping provisions for roadside

plantation.

• The corners and bends would be made in such a way as to offer the vehicle operator, a clear

visibility of at least 30 m along the road.

Storage and prevention of top soil:

The soil in the mine site can be described as medium textured, rocky, white & reddish brown in colour.

The soil cover of mineable areas with low neutrient level is devoid of any vegetation cover. While

scraping the top soil cover of mineable area by a bulldozer prior to removal of overburden layer.

The soil removed shall be stored and preserved in the earmarked dump areas for future use. The top soil

will be stored separately in the area earmarked for waste dumps to be located at the southern portion of

the lease area. It may be noted that once the in-situ soil is disturbed by scraping, soil particles los their

coherence and tendency to stick to one another. The soil therefore needs to be graded and compacted at

the dump site. The soil quality may be upgraded by adding suitable amendments and organic manure to

improve the nutrient levels. The soil stockpile heights shall preferably be restricted to 3m and the surface

vegetated with fast growing shrubs, creepers or grasses to prevent erosion and loss of nutrients. Topsoil

thus stored and preserved would be utilized as early as possible by spreading the same over the

overburden dump and during mine pit rehabilitation for the purpose of vegetation growth.

Soil erosion control:

The soil erosion is expected to be very less due to the lease area being plain and undulating. The

overburden and topsoil dumps would be provided with check dam/bund wall to prevent the carryover of

the soil particles/Silt to the drainage channels on the slopes during monsoon period.

Land restoration:

Mining will be carried out in accordance with rule 32 of GCDR,1999, Obliging this rule, restoration,

reclamation and rehabilitation of the land affected by mining will be done by back filling, soil amelioration

and afforestation. This will be taken up on need basis before the conclusion of mining operations. The

back filling of mine starts from the eastern end proceeds towards western side. Reclamation of the effected


State.


P a g e | 79

land includes, back filling, drainage development spreading and fertilizing the soil leveling and revegetation

etc. Care will be taken to implement the said factors.

5.6 Restoration of Flora And Fauna & Afforestation Program:

The environment management plan to mitigate the adverse impacts on flora and fauna of the core zone

comprises mainly of afforestation with the dominant native species. The development of green belt along

the boundary of the mine brings an aesthetic look. The fauna which was scared away due to the mining

activities shall slowly restore. The restoration of Fauna shall be accelerated by the introduction of few

native species also. The pits shall be fenced to prevent inadvertent entry of the animals. The working of

the mine is restricted to daytime only. A composite plan of greenbelt development within ML area will be

implemented. The plan is prepared taking into consideration he growth of diverse species mostly of local

origin. The species to be planted should be compatible with leguminous species are also included. The

species selection also takes into account various other proposes like erosion control, economic value,

medicinal value as well as aesthetics. For carrying out this green belt development program within the

acquired area

5.7 SOCIO –ECONOMIC DEVELOPMENT MEASURES

The Development of the proposed project will also take into account certain social obligations involving

economic and educational up-liftment of the local population. This may be in the form of extending their

cooperation to the state government and the dedicated NGOs in ventures such as providing educational

aids to the schools, opening for primary health centers, providing financial assistance for setting up agro-

based cottage industries, improving sanitary conditions in selected villages, etc. The main objective of this

development programme is to make the project society friendly as part of sustainable development

measures.

Health and Safety

Legislation in Indian Mines requires care for occupational health care and safety of mine workers as an

integral part of the mine production management.


The mine workers are generally prone to occupational health problems relating to dust and noise. In mining

operations, the workers may get affected with lung diseases resembling pneumoconiosis due to presence

of dust ,when exposed for a prolonged period to mineral dust particles of size less than 5 microns

,particularly in the range of 1-2 microns .Indian Mine Regulations amended in 1988-89 lay down norms for

safe limits of free silica levels in respirable dust in the work zone .it would ,therefore be necessary to keep

the work zone environment free from dust pollution by adopting the controlled measures proposed earlier

.Workers exposed to high dust levels would be provided with dust masks.

The major occupational health problems relating to noise range from physiological and psychological

problems resulting in loss of concentration to permanent impairment of hearing ability. To prevent this noise

related occupational health problems, the necessary control measures as outlined earlier would be helpful.


State.


P a g e | 80

Medical facilities:

For the proposed mining operation, adequate medical surveillance will be carried out, covering routine

checkup and treatment of affected workers as required. The medical staff will be familiar with the latest

diagnostic tools for occupational diseases. First aid medical kits would be made available at he work spots.

Drinking water:

Drinking water should be supplied at rest shelters, canteens, workshops etc. The mines rules specify a

minimum per capita requirement of 2 liters per day. Drinking water taps shall not be within 6 m of any

washing place, urinal or latrines as per mine regulations. The management has promised to spend an

amount of Rs,50,000/-per annum for the developments of drinking water facilities in the nearby villages.

5.8 SUGGESTED ENVIRONMNETAL MONITORING PROGRAMME

No management plan would give the desired results unless it is monitored regularly, analysed and

corrective actions taken accordingly. It may be noted that environmental management plan documents

should not be considered as a conclusive one. It shall be updated regularly for the purposes of having an

effective management of the environment. This can be achieved by conducting regular environmental

audits and planned targets. A monitoring programme is suggested, which is presented in Table 5.2 check

GEOLOGICAL RESERVES

Recoverable Geological Reserves: 6,83,275 m3

Life of Mine is = 683275 m3/9600 m3 = 71.17 years

MINING Mining Methodology:

The method of mining is Open cast semi mechanized method by using drilling & blasting by low

explosives and wire saw cutting and developing multiple benches with 6m height each.

Sheet rock zone: if sheet rock is encountered,

Splitting of primary block from mother rock: The mining will be followed in the form of key cut.

This involves

Loosening of the primary block from the mother rock: As the primary block is 4m X 3m X 2m

low benches method is used, where in vertical and horizontal cutting is done by diamond wire

sawing. Splitting will be done by using low chemical explosive like ECM/CaOH. Vertical cutting

also will be done with diamond wire sawing in the face attached to the mother rock.

Horizontal cutting: If horizontal joints are available they will be made use of. if not, horizontal

cutting will be done by diamond wire sawing.

Secondary Cuts: This involves shaping and squaring of primary block. When the bench height

is less than 6m, low bench method is adopted where in vertical cutting is done by drilling and

Splitting will be done by using low chemical explosives like ECM/CaOH.

Secondary splitting and segment tipping: This are done by drilling closed space holes (along

a line) down to depth and the secondary block will be removed by easily by just pulling it with the

help of excavator.

Transportation to dressing yard: Transportation will be done by using cranes and tippers

depending upon size of the block. Blocks will be removed from working site to dressing yard.

Block dressing: The commercial blocks will be dressed at the corners with minimum wastage. If sheet rock is encountered

Separation of large primary blocks from the mother rock by pre-splitting (primary cut):

The rock is exposed as a sheet. Diamond wire saw will be used to cut primary block from the

mother/ insitu rock. The size of the primary block is 4m X3m X2m (l x W x B) i.e. 24 m3.


P a g e | 3

Subdivision of large(primary)block into secondary blocks (Secondary cuts):

Secondary blocks of 3.3m X2.0m X 2.0m will be cut. Secondary cutting will be done using

compressors (6-7 bars,1X900), down the hole jack hammer. The other machinery required is

tippers for transport

Production of commercial blocks by production cuts:

Commercial blocks will be produced by selecting the blocks free from any mineralogical or

structural defects. They will be marked and they require only segment tipping. Finally blocks of

3.3m X2.0m X 2.0m ((l x W x B) or 2.5m X 1.5m X1.5m and 1.8m x 1.2m x 1.0m sizes will be cut

depending on the requirement. If it for monuments 1m X 0.5m X0.5m will also be cut.

HANDLING OF WASTE AND SUBGRADE MATERIAL: Solid wastes:

Removal of weathered rock and the rock waste is the only solid waste that will be generated from

this mine. It will be removed and will be dumped along the northern portion of the lease area

where already a dump exits, which will be simultaneously used during mine reclamation. From

the solid waste that is generated during the primary mining activity blocks that are useful for cutting

tiles and slabs will be separated. The remaining material will be used as road metal or building

material. All the care will be taken to minimize the waste generation at the source.

About 7,344 cum/year waste rock will be generated. The total waste will be stocked separately in QL area. From the waste equant dressing and will be used for the domestic consumption. The waste of various dimensions less than 2X 2' X 2' will be used for back filling the quarry. It is also supplied to crushing plants and is used as road metal. The left-out waste will be used for back filling the quarry, which will be covered with soil added with soil conditioners and mine will be reforested. In order to stabilize the slope and to prevent slope failures, Geo textile mats shall be laid over the waste material, this mat shall cover the dump area and reduce soil erosion thereby enhancing the growth of vegetation.

Air Pollution control measures:

The present ambient air quality measurements in the mine area are well within the limits. Due to proposed production of 9600 cum/year of Colour granite, there will be marginal increase in dust concentrations. Mitigative measures suggested for air pollution control are based on the baseline ambient air quality monitoring data from the point of view of maintenance of an acceptable ambient air quality in region, it is desirable that air quality should be monitored on a regular basis to check it vis-a-vis the standards prescribed by CPCB and in cases of non-compliance appropriate mitigative measures shall be adopted.

The following dust prone areas are identified for adopting proper control measures in the mine area i) Blasting ii) Excavation iii) Transportation The environmental control measures which will be implemented to control the fugitive dust released from the proposed production are given below:

• Wet Drilling system and Dust proof

• Optima wire saw cutting (Using water reduces dust)

• Use of sharp drill bits for drilling holes. The charge concentration of the explosives will be between 10-40 grams per linear meter.

• Water sprinkling arrangements such as specially fabricated tankers mounted on tipper are deployed at mine site to control the fugitive dust generation from the haulage roads.

• Regular grading of haul roads and service roads to clear accumulation of material.


P a g e | 5

• Avoiding blasting during high windy periods, night times and ternperature inversion periods.

• Excavation operations are suspended during periods of very strong winds.

• Massive Afforestation for control of dust emissions.

• Spraying of water on sub grade stacks.

• The vehicles and machinery are kept in well-maintained condition so that emission of fugitive constituents is minimized.

• Plantation of wide leaf trees, creepers, tall grass around working pit, along roads will help suppress dust.

• Tall trees with an average height of 5 m will be developed all along the boundary of the lease area to minimize the dispersion of the dust from the mining.

• Periodically monitoring of air quality to take steps to control the pollutants. Vehicular emission control (VEC)

Vehicular emissions from diesel operated transport equipment can be contained. by avoiding idle running and overloading of the engine. In addition, the engines shall be periodically serviced to ensure proper tuning and exhaust gases monitored on a regular basis to check smoke and CO levels NOSIE QUALITY

Noise pollution control.

The ambient noise level monitoring is carried out in and around the proposed mine shows that ambient noise levels are well within the stipulated limits of CPCB. Noise generation may be for an instant, intermittent or for continuous periods, with low to high decibels. Periodic inspection and checks of the risk prone areas and equipment’s have to be conducted.

To control noise pollution during the proposed mining operations following steps will be practiced

• The noise generated by the machinery will be reduced by proper lubrication of the machinery and equipment.

• The workers employed should be provided with personal hearing protection equipment, with earmuffs combined as protection from the high noise level generated at the plant site.

• The provision of green barrier along the boundary will further. reduce the propagation of noise level generated.

• Limiting time exposure of workers to excessive noise. • Carrying out blasting only during day time and avoiding the same on cloudy days and

when strong wind blows across. • Speed of trucks entering or leaving the mine is limited to moderate speed of 25 kmph to

prevent undue noise from empty tippers.

WATER QUALITY

Impact on the ground water environment

About 10 m3/day (peak demand) of water is required for the proposed project. The Entire water requirement will be met from a bore well in the core zone. The safe yield of tube wells in this region ranges from 1.5 to 3.0 LPS. As such, the ground water with drawl from the project will not impact on water availability in this study area.

PROPOSED MITIGATING MESAUSRES

Raw water treatment: It is planned to draw 10 KLD of water from the ground water resources for dust suppressions. Green belt development, drinking and sanitation for the drinking water, chlorination shall be done along with a UV and water filtration for drinking.

Waste water:

The Mine as such would produce mine seepage water during underground operations and also nominal amount of sanitary and canteen waste water in the range of 1-2 KLD. It is proposed to treat this water in a septic tank. The mine seepage water would be used for dust suppression and Green belt purpose in the QLA. The domestic effluent is sent to septic tank followed by soak pit.

Silt water control:

There shall not be any significant silt as there shall be very less amount of solid waste generated. During the monsoon period, runoff from the OB- Dump and Top soil, Topsoil dump would be checked by the garland drains and retaining wall. The retaining walls would be made from boulders by cement pointing. In addition, the overburden dump would have garland drains all around for each terrace of adequate size so that velocity is appreciable reduce to enchase the seating of the fine particulate. Contour Trenches shall be dug with in the core zone to assist in ground water recharge.

ANTICIPATED IMPACTS ON LAND

The mining area is a hilly and undulating land. The top soil in the mining area is scanty. Whatever is available will have to be excavated during the development of the mine pits. Most of this soil is rocky in nature and will get mixed with the over burden. Temporary storage of top' soil over burden may cause some loss of nutrients and this cannot be avoided. Since, the mining area is contained to only 29.00 Ha, the effect on the land environment will be negligible. There shall be no leachate from the lease area. There shall be soil erosion of the loose soil of waste dumps which shall be contained. The adverse effect of the mining activity on the bio diversity shall be mitigated by employing proper mitigating measures.

PRPOSED MITIGATING MESURES

The land management plays an important role in reducing the adverse impacts caused by surface mining operation. Land management is required in the key areas like land use scheme within the QL area, calendar plan, mine bench advancement to arrest indiscriminate degradation of landform, top soil preservation, overburden management, soil erosion control and the restoration of the mine pits. On each of these prime areas of land management, the following schemes are proposed.

Land use

The project covers a total ML area of 29.00 hectares of Government Revenue land. The Quarry lease area is a small mound / plain area and is fit for quarrying. The adjacent area is also of similar type. Hence suitable for mining purpose only. However, in the plains the land use pattern is mainly agriculture. Dry crops are grown.

IMPACT ON BIOLOGICAL ENVIRONMENT (Flora & Fauna)

The area is devoid of any significant growth of shrubs and trees and is mostly covered with granite. The entire vegetation, though scanty will disappear in areas where mining, dumping of waste rock over burden road formations and infrastructural facilities. The loss will be more than compensated by compensatory afforestation and green belt development planned in and around the mine which will rather increase the green cover and vegetation.

The fauna in the vicinity of the mine is restricted to common small species. The mine lease area is surrounded by few other Quarries and hence no significant fauna is found in the lease area. All these will be displaced from mine area and form new habitations away from mine. There are no endangered, threatened, rare or protected species in the study area. Some of the fauna displaced scared away by the project may reappear in the mining area after abandonment of the mine. As such the impact of mining project may have

• Low Impact on Regional Biological Environment. • The Duration of the impact will be through out the mining period. • No Significant impact on Biodiversity on regional scale.

IMPACT ON SOCIO-ECONOMIC ENVIORMENT

Operation of mining and associated activates will result in some socioeconomic impacts of direct

and indirect in nature.

Impact on human settlements

The mine is an existing project. There is no human displacement within the mine lease area. The

project has no impact on human settlement.

Population growth

The project will have little impact on population growth due to immigration of people for

employment. Since the project is an ongoing project, no migration of labor is envisaged

Impact on literacy and educational facilities

The literacy level of the project area (buffer Zone) is likely to increase as there will be in flux of

educated people taking up jobs in the mining. Life style may change.

Impact on civic amenities

Network of roads, telephone facilities, education facilities and health care facilities may be

improved due to project. A higher demand for food facilities may appear in buffer Zone.

Impact on employment

The mine shall employ 70 people. In addition to the employment in the mine additional people

shall also get employment due to allied activates like transport and related business. In all, the

mine shall generate an additional employment to around 60 people.

Impact on economic aspects

Per capita income shall increase slightly due to direct and indirect employment.

Impact on industrial establishments

Small scale industries and small business centers may likely to come up in the vicinity of the

project.

PROPOSED MITIGAING MEASEURES

Socio-economic development

The development of the proposed project will also take into account certain social obligations

involving economic and educational upliftment of the local population. This may be in the form of

extending their cooperation to the State Government and the dedicated NGO’s in ventures such

as providing educational aids to the schools, opening of primary health centers, providing financial

assistance for setting up agro-based cottage industries, improving sanitary conditions in selected

villages, etc. The main objective of this development programmer is to make the project, society

friendly asper of sustainable development measures.

Health and safety

Legislation in India Mines requires care for occupational health care and safety of mine workers

as an integral part of the mine production management.


The mine workers are generally prone to occupational health problems relating to dust and noise.

In mining operations, the workers may get affected with lung diseases resembling

pneumoconiosis due to presence of dust, when exposed for a prolonged period to mineral dust

particles of size less than 5 microns, particularly in the range of 1-2 microns. Indian Mine

Regulations amended in 1988-89 lay down norms for safe limits of free silica levels in respirable

dust in the work zone it would, therefore, be necessary to keep the work zone environment free

form dust levels would be provided with dust masks.

The major occupational health problems relating to noise range from physiological and

psychological problems resulting in loss of concentration to permanent impairment of hearing

ability. To prevent these noises related occupational health problems, the necessary control

measures as outlined earlier would be helpful

Medical facilities

For the proposed mining operation, adequate medical surveillance will be carried out, covering

routine check-up and treatment of affected workers as required. The medical staff will be familiar

with the latest diagnostic tools for occupational diseases. First aid medical kits would be made

available at the work spots.

Drinking water

Drinking water would be supplied in rest shelters, canteens, workshops, etc. The mines rules

specify a minimum per capita requirement of 2 liters per day. Drinking water taps shall not be

within 6 m of any washing place, urinal or latrines as per mine regulations. The management has

promised to spend an amount of Rs.50,000/- per annum, for the development of drinking water

facilities in the nearby villages.

Sanitation facility

Water flushed latrines and urinals would be provided at conveniently accessible points at the

scale of one seat for every 50 (or part) persons, with the associated facilities for disinfection.

Conclusion:

The Colour Granite mine is a proposed quarry which has surrounded by other 4 Quarry’s with in

500mts radius in the same Sy.no. with the extents of 12.00 Ha, 1.00 Ha, 2.00 Ha and 2.00 Ha

and are operating since 2009, which have obtained Environmental Clearances along with

CFE/CFO from the TSPCB. The proposed project would generate direct employment for about

70 people. The project will also provide indirect Job opportunities for about 100 people and better

economic standards to the local population by transportation, small shops and etc. The present

annual production proposed only 9600 cu.m /Year, of Colour granite, the mine shall be worked
