INTRODUCTION

Nature is very kind on the human to provide all kind of materials on earth. All kinds of minerals

are available in their raw form in the earth . Mining operations disturb the terrestrial configuration

and natural beauty of the area. The magnitude of disturbance depends upon how the minerals are

extracted from the mining area and the environmental impact depends upon the location and size

of deposits and the methods adopted for its exploration. By adopting good mining practices it is

moving towards harmonious development where both the operational and environmental

aspects are accorded due weightage.

Every quarry lease holder shall take all possible precautions for the protection of environment and

control of pollution while conducting quarry operation. Under the mining operation this

management plan is required.

The proposed quarry lease area named Sri Gandreti Seetharam of road metal and building stone

over an extent of 1.54 Ha. Located at Sy.No.7, Sompuram Village, Vepadu Mandal, Vizianagaram

District, Andhra Pradesh state submitted an application for grant of quarry lease. The asst. director

of mines and geology Vizianagaram vide File No. 8295/Q/2017 dated. 06.03.2018 submitted

proposals on the application duly recommending for grant of quarry lease in favour of Sri Gandreti

Seetharam, S/o. Late Sanyasappadu.

After careful examination of proposals the asst. director of mines and geology, Vizianagaram is

decided in principle for grant of quarry lease for road metal and building stone for the applied mine

for a period of 10 years subject to submission of approved mining plan with a condition that the

approved mining plan shall reflect the restrictions to be adopted by the application while quarry

operations. For the same the deputy director of mines & geology, Visakhapatnam sent a notice vide

939/Q3V/2018 dated.29.03.2018.

GEOLOGY AND EXPLORATION:

The eastern ghat mobile belt (EGMB) is more than 600 km in length form vizianagaram in the North to

Ongole in the South. This belt is more than 100 km in width in Northern part and tapers down to less

than 20 km in the south, it has broad actuated trend with westward convexity. The NNE-SSW trend in

the southern part of the belt changes NE-SW in the North. EGMB is divided into 3 longitudinal

zones viz.,

1. Western-Charnockitic Zone

2. Central – Khondalite Zone

3. Eastern – Migmatite Zone

While in the northern parts in Srikakulam, Vizianagaram & Visakhapatnam districts the central

Khondalite Zone occupies major part of the area. Whereas western Charnockite Zone occurs in the

Southern part. The rocks in this belt are represented High grade granulite facies of Metamorphism and

suffered by complex deformation. The stratigraphic succession of EGMB is as follows:

Recent Alluvium, Beach Sands, River Sand

Quarternary Laterite, Lateritic Soils

In vizianagaram district the EGMB is represented by vide range of litho units viz: Charnockites,

Khondalites, two pyroxene granulites, Migmatites, Leptynite and Intrusive Porphyroblastic

Charnockites. Large enclaves of Acid Charnockites, Khondalites and Meta Basic rocks occur within

Migmatites, which are largely seen in the area lying between R.Vamsadhara and Coast line.

DETAILED DESCRIPTION OF GEOLOGY AND LEASE AREA:

The present area is occupies by Charnockites, charckites is a garnet bearing quartz plagioclase

pyroxene, grey in color (Graniulite) with typical platly “Granoblastic”texture. This rock type might have

been derived from high-grade granulite facies metamorphism of a pile of volcanic intrusive. Tis rock

type is formed in N-S direction and this type of material is being excavated for road metal & Building

stone during previous years.

The material excavated from this area will be crushed as chips and the chips will be supplied to the

road works & building constructions. Accessory minerals like biotite and opaque cannot be identified

megascopically.

Entire quarry lease applied area is covered with road metal & building stone which is rising upto 50 m

above ground level trending SE-NW, the length of the exposed body measured 140 m in the area with

an average width of 99 m.

The road metal & building stone can be extracted from the rock available n the quarry lease applied

area which is useful in civil constructions purposes.

PROGRESSIVE MINE CLOSURE PLAN

I Existing Land

Use Pattern

The quarry lease applied area is surrounded by barren lands and low level

hillocks comprising Road Metal & Building Stone of good quality. The

surrounding area of the quarry lease applied area are quarries for Road Metal

& Building Stone and beyond are agricultural lands

Ii Water Regime

The subject area is located on a hillock and the surrounding areas around are

agricultural lands.

The ground water occurs under confined conditions in both hard rock and

alluvium which are shallow in nature.

No impact on surface water or ground water is foreseen due to quarry

operations.

Iii Flora and Fauna

The whole area is occupied by scattered sparse vegetation of thorny trees and

small bushes. In the quarry lease applied area no wild animals are witnessed

as per the statements collected from the local population, since 50 years

Iv

Quality of Air,

Ambient Noise

Level and

Water

Air quality is good but at quarries it is filled with dust, due to haulage on the

road, blasting etc.

The noise generated mostly due to blasting, drilling, vehicular traffic

Road Metal & Building Stone quarrying will not affect water quality.

v Climatic The area is falling under tropical zone. The area is having Humid climate. The


Conditions temperature recorded in this area is 25°C in winter and about 48°C in summer

seasons. The wind direction is in SW to NE. The average annual rainfall of the

area is 1000 mm.

Vi Human

Settlement

The nearest village Ramaswamipeta is situated 1.250Km due NE of the quarry

lease applied area, having approximately population of 400 No’s. Agriculture

and sheep breeding are important profession of the people living in the village

besides involving themselves in quarrying activity.

Vii

Public

Buildings,

Places &

Monuments

No public buildings, important places and monuments are seen in and around

the quarry lease applied area. The applicant will adopt the safety measures

while conducting the quarry operations as per the Regulations of

Metalliferrous Mines Regulation 1961

Viii Sanctuaries No bird or animal sanctuaries are existing in 10 Km radius

Ix Eco-Sensitive

Areas

No Eco Sensitive are existing in 10 Km radius

LANDSCAPE CHANGES:

During the first 5 years 6,438 M2 of the quarry lease applied area will be reduced by 18 M.

AIR QUALITY:

The project includes various quarrying operations involving

• Development of Benches

• Approach Roads

• Haul Roads

• Drilling

• Blasting

• Excavation and Transportation

These operations generally result in generation of dust and thereby pose health hazards. However,

adequate control measures will be provided at every stage of operation such as water sprinkling at

loading and unloading point and on haul roads before transportation to reduce the fugitive dust

emissions.


Heavy Earth Moving Machinery like excavator, dumpers, dozer and other transport vehicles will

emit gaseous pollutants mainly CO and NOx.

The generation of dust is anticipated from various quarry activities i.e. drilling, blasting, loading,

haulage, unloading, and other activities related to quarry.

The increment in the fugitive emissions will be due to material handling and transportation

activity. These will be restricted to the lease area only by adopting water sprinkling, which will be

practiced at the quarry site to control air pollution load.

Ambient air quality standards promulgated by National Ambient Air Quality applicable to the

subject project are given below.

Dust levels will be higher within the active operational areas (quarry area) due to blasting and

transportation. However, in the buffer zone it is not likely to be affected by dust problems, when

proper dust suppression measures are taken.


AIR QUALITY MANAGEMENT

The following measures will be adopted to mitigate air pollution generated due to the quarry

activities :

Water sprinkling while drilling

Rock breaker will be used for breaking over size boulders in order to reduce dust

and noise generation

Water spray on haulage roads & proper maintenance of haul roads will be done

Development of green belt around lease boundary, roads and other places will be

carried out to control the air pollution

Personal Protective Equipment like dust mask will be provided to all

employees working in the dusty areas

Proper maintenance of vehicles will be done to limit gaseous emissions

WATER QUALITY

Surface Water

There is no perennial surface water source in the quarry lease applied area. Ground water is the

source for the nearby habitation also.

Stone is non-toxic in nature. There will be no outside discharge of liquid effluent from the quarry

site.

GROUND WATER

Ground water pollution can take place only if the quarry rejects contain toxic substances, which

get leached by the precipitation water and percolate to the ground water table thus polluting

it. Any nearby wells or other sources of water can be rendered unfit for drinking and even for

industrial use.

This is not the case with this deposit as the stone or topsoil does not contain any harmful

ingredients. Moreover, stone constitutes of fairly inert and chemically non- reactive ingredients.

Water Pollution Control Measures


No waste water will be generated during quarry operation

Garland drains all along the downstream boundary of the pit.

Rainwater falling in the quarry pit will flow based on the slope into the garland drain provided

with sedimentation pits.

Noise Levels

Noise generation is from operations at quarry development, excavation and transportation of

stone.

High noise levels will be confined to work zone areas only. Noise levels get diffused rapidly with

distance.

Noise impact is mainly restricted to the work zone areas. Hence, the noise levels impact due to the

quarry operations on community is insignificant.

Noise Control Measures

The following control measures will be adopted to keep the ambient noise levels well below the

limits.

Controlled blasting with proper spacing, burden, stemming and optimum charge / delay will be

maintained.

The blasting will be carried out during less human activity timings i.e. during lunch interval or

during change of shifts.

Proper maintenance, oiling and greasing of machines at regular intervals will be done.

Green belt and plantation will be developed wherever possible.

Vibration Levels

Ground vibration, fly rock, air blast, noise, dust and fumes are the effects of blasting on

environment. The seismic wave due to explosive energy in the ground can cause significant

damage to structures and disturbance to human occupants due to vibration.

The vibration/ Particle Velocity (Peak Particle Velocity) is measured in millimetre per second. The

standards for safe limit of PPV are established by Director General of Quarries Safety for safe level


criteria through Circular No. 7 dated 29/8/1997. The safe level criteria PPV as mentioned in

Circular No. 7 of DGMS is presented below.

Blasting damage has been classified into four categories; and no appreciable damage occur when

PPV less than 17 mm / sec. So no effect is envisaged

EFFECT OF GROUND VIBRATION ON STRUCTURES

S.No. Category Description of Damage

1.

No

appreciable

damage

No formation of noticeable cracks

(PPV <17 mm / sec.)

Formation of fine cracks, fall of plaster, opening and lengthening

of old cracks, loosening of joints

2. Threshold Dislodging of loose objects, etc.

PPV – 17.75 mm / sec.)

3. Minor

Superficial not affecting the strength of structures – broken

windows. Hairline cracks in masonry around openings near

partition, broken windows. Fall of loose mortar etc. (PPV – 30

mm / sec).

4. Major

Formation of several large cracks, serious weakening of

structures, shifting of foundation, fall of masonry, ruptures of

opening vaults, etc. (PPV – 40 – 60 mm / sec)


As the distance increases the PPV value is likely to reduce. The ground vibrations generated by

blasting during the quarry operations will be maintained well within standards prescribed by

DGMS by controlled blasting and optimum charge. Ground vibrations are not likely to affect the

structures in the vicinity of quarry lease area.

VIBRATIONS AND FLY ROCKS CONTROL MEASURES

The blasting operations will be carried out by drilling and blasting. The measures for abatement of

ground vibration, air blast and fly rocks are detailed below:

Blasting will be performed strictly as per the guidelines specified under MMR, 1961.

Proper design of blast with correct spacing, burden & optimum charge / delay

Supervision of drilling and blasting operations to ensure blast design geometry as per planning

Sub-drilling will be kept adequate to eliminate toe formation

Supervision of drilling and blasting operations to ensure blast design geometry

Sub-drilling will be kept just adequate to tear-off the bench bottom

Blasting operations will be carried out only during day time as per DGMS guidelines.

Proper warning signals will be used

Adequate safe distance from habitation as per standards from centre of blasting will be

maintained.

Drilling parameters like overburden, depth, diameter and spacing will be properly designed to

ensure proper blast.

Effective stemming of the explosives will be done in the drill holes.

Water Environment

The surface water environment will not be disturbed as the quarry is far off from the water

courses.

Acid Mine Drainage

No acids will be generated from Road Metal & Building Stone quarries

Surface Subsidence

No subsidence is anticipated in this regime as the basement rock is massive


Socio Economics

The main occupation of villagers is agriculture and sheep raring. The commencement of quarrying

activity in this area improved the socio-economic status of the local people by creation of

employment and paying taxes to gram panchayath.

The quarrying in this area does not involve any hazardous methods. The quarrying will be Open

Cast Semi Mechanized Method. In this, the possibilities of small injuries is anticipated. The

applicant is providing First Aid facilities at quarry site.

Historical Monuments

No historical monuments exist within 5 Km radius

Bio-Diversity

No impact will happen to the Mankind, Flora and Fauna by the quarry operations, excepting minor

vibrations due to blasting, sound pollution and dust which will be under control and within the

permissible limits.

PROGRESSIVE RECLAMATION PLAN

The quarry lease applied area is part of hillock.

The pits will be utilized for water storage and water harvesting structure.
