subsequent amendment MoEFCC Notification S.O. 141 (E) dated 15.01.2016, the

project area lesser than 5 Hectares are classified under B2 category for the purpose

of Environment Clearance. Hence, this project falls under B2 Category and require

Environment Clearance (EC) from DEIAA/DEAC, Pathanamthitta, Kerala.

1.2. NATURE OF THE PROJECT

The area was previously operated for quarrying of building stone by the applicant.

Previous quarrying has rendered valuable data on nature of the deposit, Colour,

Probable depth persistence, 95 % of recovery, quantum of production expected,

etc.,.. The area contains mostly gneisses and Charnockite rocks. They are fine to

medium grained, composed of predominantly quartz and feldspar. The Charnockite

is composed of blue quartz and microcline feldspar with Biotite mica and

hypersthenes pyroxene and accessories.

Open cast, semi-mechanized mining will be adopted to extract building

stones of required size from the area for which lease applied for. Aspects considered

for quarrying are construction of semi-permanent structures, planning for the

development / production works, formation of faces, laying of approach road to

various benches for movement of dumpers, recruitment of man power, deployment


6

of machinery, selection of dump sites, stacking yards etc. Top soil / overburden,

weathered materials shall be removed prior to development of working benches.

1.3. NEED AND SIGNIFICANCE

Building stones play a vital role in roads, concrete and building products. They are

used in walls and paving slabs as it is weather resistant and for its aesthetic appeal.

The aggregates of the stone is crushed and sorted into various sizes for use in

concrete, coated with bitumen to make asphalt or used dry as bulk fill in

construction because of its strong physical properties. Thus mining of Building

stones supports the country in improving the infrastructure as well as the economy.

It also supports the day to day life by comforting the living environment.

1.4. DEMAND – SUPPLY GAP

As Building stone is a significant raw material in the construction sector, the

demand exists in the market throughout the year. Thus quarrying of the mineral

finds consumer easily in the local market.

1.5. IMPORT VS INDIGENOUS PRODUCTION

Building stone exists in the proposed site and does not require any raw material to

be imported for the production process. The extracted blocks are broken into

required size for selling. Send to crushers if required.

1.6. EXPORT POSSIBILITY

Not applicable since the project meets local demand only.

3.5.1. Open cast mining

Under, Reg.106 (2) (b) of MMR, 1961, the bench height is designed as 5m and the

bench width should not be less than bench height. The slope of the benches should

not exceed 60° from horizontal. As far as mining of minor mineral is concerned,


10

observance of provisions of the regulations 106 (2) (b) as above is seldom due to

various inherent petro genetic and mining difficulties. The bench height is designed

equal to height of boom of the excavator. Hence, the applicant is suitably directed to

obtain necessary relaxation from the chief inspector of mines, for which provision is

available within the regulation 106 (2) (b).

A bench height of 5m and a width not less than the height and five working

benches, each with a height of 5m as equal to the height of the excavator boom and

the width more than 3m is proposed to be maintained for safe movement of

machinery. The bench slope is maintained not more than 60° from horizontal.

The proposed Bench dimension to be maintained in the five years period of

mining plan is described in the production schedule.

S1 fencing shall be constructed at the top of high benches in order to safe

guard the unauthorized entry of men and machinery. In the case of entry and exit of

pit(s), G1 fencing as a parapet should be made to control tress passes.

3.5.2. Drilling

3.5.3.1. Measures proposed to minimize ground vibration due to blasting

The following steps shall be adopted to control ground vibration during blasting.

i. Geometry of blasting pattern like burden, spacing and inclination of hole

should be

Burden (m) * Spacing (m) Inclination

0.60 x 0.75 70°

ii. High strength explosives like slurry in the form of cartridge should be used.

ANFO mixture for shot holes should not be used which may cause huge fly

rock fragments in view of critical diameter problem.

iii. To control vibration abatement, use delay or relay arrangements with

specific charges

iv. Charge per hole should exceed the powder factor designed for each hole

based on quantum of blasting, strength of rocks, fracture pattern etc.

v. In case any objection from the public, a long trench in the direction of

blasting near lease boundary may be opened to a depth of 2m to control

longitudinal waves (P-waves) to arrest any damage to infrastructures.

Chapter 5: Planning Brief

5.1. PLANNING CONCEPT

Excavation of building stone is planned and described in section 3.4 and 3.6.

Proposed land is a Patta land which does not come under Residential, Forest or any

other sensitive land classification. As a small project, it is not demanding any town

or country planning. However, approach roads and haul roads will be laid for the

transportation of excavated materials to the market and to the dump.

5.2. POPULATION PROJECTION

Population of the nearby villages are as in table 5.1. Population characteristics and

Occupational characteristics of the Erathu Village, Adoor Taluk, Pathanamthitta

District is given in table 5.2 and 5.3 respectively. The proposed project will not affect

the village population, and hence population projection is not significant. However,

it provides occupation to about 14 persons of which 80% of them will be from the

local villages. Other than mine employment, workshops, spare parts, tyres and tubes

and related several self-employment opportunities.

5.5. AMENITIES/ FACILITIES

List of equipments and materials required are discussed in Chapter 3 and listed in

Table 3.3 to 3.5.

5.6. HAZARDS AND RISK MANAGEMENT

5.6.1 Explosives

Blasting is done by means of explosives which are hazardous during handling,

storage and blasting.

5.6.1.1. Storage and Handling

The Applicant is advised to store the explosives as per the Indian Explosives Act,

1958 and the Explosive Rules, 1983. Necessary permissions should be obtained

from the Joint Controller of Explosives to store and uses of explosives in the quarry

in the magazine permit under Form - 23 or Agreement shall be made with holder of

Form - 22 who can supply and fire explosives as per safety practices. However

blasting in the mine or quarry shall be done as per the MMR, 1961 under the

supervision of Mines Blaster certificate holder, appointed under Reg. 160 of

Metalliferous Mines Regulations, 1961.

5.6.1.2. Blasting

Poorly designed shots can result in misfires early ignition and flying rock. Safety can

be ensured by planning for round of shots to ensure face properly surveyed, holes

correctly drilled, direction logged, the weight of explosion for good fragmentation.

Blast design, charge and fire around of explosives should be carried out by a trained

person.

5.6.1.3. Drilling

Slipping and Falling of labours from the edge of a bench during drilling is possible.

Part of training should include instructions to face towards the open edge of the

bench so any inadvertent backward step is away from the edge. Suitable portable


29

rail fencing which can be erected between the drilling operations and the edge of the

mine can be provided. Attachment of a safety line to the drilling rig and provide

harness for the driller to wear can be done. Newer drill machines are provided with

cabin which controls noise level within cabins. Driller operators should be protected

with ear protection.

5.6.2. Loading

Possible risks during loading of mined rocks are falling of rock on the driver, plant

toppling aver due to uneven ground, failure of hydraulic system, fires, fall while

gaining access to operating cabin, electrocution in Draglines, failure of wire ropes in

Dragline. In order to overcome these risks:

Operator cabin should be of suitable strength to protect the driver in

event of rock fall.

Electrical supply to dragline should be properly installed with adequate

earth continuity and earth leakage protection.

Wire rope should be suitable for work undertaken and be examined

periodically.

Ensure that loaders are positioned sufficiently away from face edges

5.6.3. Transportation

Brake failure, lack of all-around visibility from driver position, vehicle movements

particularly while reversing, rollover, Vibrations, Noise, Dust and improper / no

signalling are some of the factors causing risk. This can be avoided by following

measures:

Visibility defects can be eliminated by the use of visibility aids such as

closed circuit television and suitable mirrors.

Edge protection is necessary to prevent inadvertent movement.

Seatbelt to protect driver in event of vehicle rollover.

Good maintenance and regular testing necessary to reduce possibility of

brake failure.

Avoid driving at the edge of roadway under construction

Heavy earth moving equipment and vehicle drivers and those giving

signals should be well trained.

5.6.4. Unstable face

Chances of Rock fall or slide exists. Regular examination of face must be done and

remedial measures must be taken to make it safe if there is any doubt that a collapse

could take place. Working should be advanced in a direction taken into account the

geology such that face and quarry side remain stable.


30

5.6.5. General safety measures

Provisions of the Mines Act, Rules and Regulations orders made there under shall be

complied with, so that the safety of the mine, machinery and persons will be

ensured. Permission, relaxation or exemption wherever required for the safe and

scientific mining of the deposit will be obtained from the Department of Mine Safety.

Copy of Agreement for handling of Explosives under License Holder at Proposed site

is given in additional document.

Safety kits should be located in easily accessible place with major first aid

materials in it.

Entry of any unauthorized person into mine and plant areas shall be

completely prohibited

Arrangements for fire fighting in the mine’s office complex and mining area

Provision of all the safety appliances such as safety boot, helmets, goggles,

ear plugs etc. shall be made available for the employees

Mining will be undertaken in coexistence with the requirements of the

Mining Plan which shall be updated from time to time

Handling of explosives, charging and blasting shall be undertaken only by a

competent person

Adequate safety equipment shall be provided at the explosive magazine

All the mining equipment shall be maintained as per the guidelines of the

manufacturer

Elevating the awareness of employees, contract workers and public as a

whole by celebrating Annual Safety Week which includes various

competitions like posters, essay, slogan, quiz etc.

be spread for plantation.

6.7. POWER REQUIREMENT AND SOURCE

Details of the power requirement and source are as discussed in section 4.5.2 of

Chapter 4.


33

Chapter 7: Rehabilitation and Resettlement (R&R) Plan

Being a small building stone excavation, the project does not involve displacement

of any residents or public infrastructures. Thus resettlement is not proposed.

Humus top soil shall be used for rehabilitation and afforestation purposes. In

case of steep slopes, fencing shall be made to control, inadvertent entry of animals

and local persons. The mined out area shall be used for storage of rain water with

proper barricade which will help recharge of regional ground water table. No major

dumps, however plantation shall be made over small dumps to prevent soil

erosion\wash outs and help ecological balance.

Fencing shall be made around open cast working as per DGMS circulars with

S1 type fencing. Back filling shall be done to a reasonable extent and depth during

closure of mine.
