3. GEOLOGY AND EXPLORATION:

a) Brief description of the topography, general geology and local/mine geology of the

mineral deposit including drainage pattern.

Location and accessibility: The Department of Mines and Geology Govt. of Karnataka has

granted permission to extract building material by quarrying from an area of 1 acres in part of

Sy.No 110 of Tailagere Village, Kundana Hobli, Davanahalli Taluk, Bangalore Rural district bound

by the coordinates of longitudes 130 18’ 13.2’’ to 130 18’13.5’’ and latitude 770 40’ 23.1’’ to 770

40’ 29.3’’ as depicted in the Survey of India toposheet no 51 H/11. The sketch map of the area is

given in plate -01

Topography: The topograpgy of the essence consists of stone ridges and slops/ gradient in all

directions. The height of the mounds/hill ranges from 792 m to 980m. Above the MSL.

Topography is both structurally and lithologically controlled. Hill/mound ranges extend in N

100W – S 100E. The subject area falls within this region confining to a part of Tailagere Village.

The highest elevation is 976 m and lowest elevation is 966 m above the MSL. The slopes are

drained by nallas & are outside the quarry lease area.

Regional geological setting: Geologically this southern part of Mysore plateau is divisible into

the Western Dharwar nucleus and it is the eastern greenstone belts, both sand witched by a

linear belt of Closepet Granitoids trending in N-S direction. Older gneisses form the basement for

all these suites of rock. A tabular statement of the regional stratigraphy follows:

Lithoassemblage Group or Suite Age in Million years

Granites and Granodiorites Closepet Granite 2550 Million years

Granitoids and Gneisses Pensisular Gneiss II 2600-2500 Million years

Greenstones - predominantly

meta volcanics. Eastern Greenstone Belts 2700 Million years

Meta volcano sedimentary

sequences Dharwar Supergroup 2800-2700 Million years

Banded biotite gneiss, tonalite Peninsular Gneiss – I of PGC 3000-2900 Million years


trondhjemite gneisses

migmatites and older

Granitoids

The vast stretches of southern and central Karnataka occupied by gneissic rocks were earlier

referred as a single lithoassemblage called Peninsular Gneissic Complex (PGC); this is divisible

into two distinct suites (Ramakrishnan, Geo Karnataka, MGD Centenary vol. 1994). The eastern

suits called Bangalore Supersite (PG-II) are considered younger to its western conterpart

enveloping the western Archaean nucleus of Dharwar Craton (Radhakrishna, 1997). Both the

Bangalore Supersuit with the adjoining Closepet Granitoid is termed as Dharwar batholith by

Hegde, Vasudev and Chadwick, Geological studies- special report, DMG, 1999).

The rock types recorded in this region are grey Biotite gneiss leucogranite hornblende Biotite

granite and migmatites with soda rich feldspars as the main mineral constituent.

Local Geology: The quarry area exposes grey coloured medium grained Biotite gneiss and is

slightly migmatised. Alternate bands of the crudely aligned felsic and mafic minerals viz. feldspar

and Biotite define the gneissiosity. The rock is hard and compact. Bright looking fresh cut

surfaces indirectly suggests its late Archean accretion and migmatisation. The general trend of

the gneissiosity is NW-SE with a steep dip due NE.

The rock is essentially made up of plagioclase, quartz and mica. Alignment of the minerals and

texture of the rock suggests that it could yield sub prismatic, sub angular shaped gravels when

crushed. As the bed rock are surfacing on the ground level itself direct quarrying of the material

can be taken up after peeling a few cm thick of upper semi weathered crust.

The area is composed generally of Granite gneisses exposure trending N 100W to S100E as a

narrow belt. The Geological setting of this area is of “Closepet Granite” the name given to this

complex of medium grained texture to light color to light grey color, monzonites and monzo-

granites traversed by fine grained grey to pink color types, pegmatite’s and aplites.. The area is

completely of grey color granite gneisses and is moderately disturbed with well-developed joints

and gneissic complex. Building stone (Granitic-gneisses) out crops occur preeminently exposed

along the Quarry lease area.

The grey color Granitic-gneisses (sheets & Boulders) the rock units as exposed in the quarry

lease area can be made out from the map (Plate3)


The physical properties of the material to the quarried are given below

Nomenclature: grey coloured medium to coarse grained Granitic gneiss.

Essential minerals: Plagioclase feldspar quartz and hornblende.

Sp.gr: 2.6 to 3.0

Hardness on mohs scale: 6.0 to 6.5

Compressive strength: 1500kg/Cm2

Due to it fresh un weathered nature required hardness and desired compressive strength, this

rock beds are well recommended for use as building material in various forms.

a) The Surface Geological plan is prepared after topographic contouring. The scale of

the Surface Geological plan on 1: 1000 is enclosed as plate no 03 & 04.

b) Geological cross sections are drawn on AA’ as longitudinal cross sections. Geological

sections are prepared at equal intervals on a scale of 1:1000. These are enclosed as

plate No. 05.

c) Exploration carried out so far in the quarry lease block includes surface geological

mapping sampling and delineation of the Building Stone based on the existing

exposures & outcrop.

3.1 Geological and Minable Reserves: The following Parameters have been considered for reserve

estimation of the Building stone deposit:

1. The entire quarry lease block is geologically mapped. The exposed dimensions of the Building

Stone have been surveyed and measured. The digitation and maps have been generated using

GIS and Auto-CAD software. Plate 3 & 4

2. The influence along the strike, for cross section has been taken as half the distance from the

cross section on both side & up to the demarked limit the Building Stone on the other side. The


length width & depth extension of the Building Stone as inferred in the cross section have been

considered for volume and reserve estimation.

3. The limiting of reserves is based on the existing outcrops of Building Stone sheets with a

maximum height (dimensions) of 930 m above MSL and from existing outcrop edge of general

ground level of 930 m above MSL is taken for proved category; further 5 m down depth is

considered for probable category reserves, while the remaining material falls under possible

resources category. This computation is arrived based on the observations from the adjacent

quarries and extrapolated.

4. For the Building Stone, a reserve is calculated on the basis of the areal extent of the outcrops

boulders sheets multiplied with the maximum height. In conventional method, the total sectional

area in square meters X Avg depth in meters and recovery factor (Weight in tones = Volume (in

Meter cubic) X Specific Gravity. Volume (meter Cubic) = Surface area (Length X breadth) X Avg

height or depth from the surface (Cross sectional area) all meters in) X recovery factor). The

Building Stone recovery is about 98% and waste (voids and mining losses) is about 2%. RF

(recovery factor) test were conducted on the Building Stone in the field and the results of the

Recovery factor is 98% for Building Stone.

Geological Reserves is Given below: for Building Stone

1. Weight in Tones = Volume (in cubic meter) X Specific Gravity

2. Volume (Cubic meter) = Surface area (Length X breadth) X Avg depth (Cross

sectional area) all in meters)

Based on the geological map and cross sections and recovery parameters highlighted above, the

different categories of reserves are calculated and presented in Annexure.

4. Indicate mineable reserves by slice plan / level plan method: The slice plan/level plan

required as per the proposed quarrying parameters is indicated in annual production plan

and the scale of quarrying operation is medium Semi-Mechanized Method.

5. The cut-off block has been considered as follows: - The cut-off size considered for Building

Stone i.e. Gravel (jelly) is 10mm and above.

6. MINING / QUARRYING METHOD: The method of working Building Stone in the Quarry lease

area for the proposed plan period is by Semi-Mechanized method of opencast quarrying.

Considering the technical parameters like surface topography, quality variations, geo-technical

aspects, required rate of production & available resources etc. it is proposed to work from the

western side of the lease boundary by adopting bench height and width of the quarry condition

with an ultimate pit slope of 450 by medium scale quarrying activity with small diamond jack

Hammer drilling followed by controlled Blasting and use of Hydraulic Rock Breaker. The bench

height and the width will be maintained as per the safety condition in the quarry activity in the

leased area. In the quarry area northeastern and south western side covered a thin veneer of

wreathed rock. Proposed eastern side of the lease area developed for the recovery of the

minerals, approachable road to quarry in the north side. The year wise Production &

Development Plan indicate the working site for disposal of waste/overburden etc. as shown in

plate no-06 & 07 The Plan showing the position of workings, proposed extensions, bench

parameters, pit configuration at the end of Plan Period is indicated in production & Development

plans as shown in Plate no.06 & 07. Due care will be taken in designing the benches by

straightening and advancing the benches for effective and economical operation at the quarry.

Since the ground water table is much below and the rainfall is moderate during monsoon,

drainage of water shall be properly coursed with series of garland canals, check dams and

retaining walls without disturbing and in harmony with the natural drainage pattern of the area.

Loading and Hauling: Loading of the Building Stone blocks to tippers of 10 or 20 tonnes

capacity will be mechanized and transported from the quarry to the stock yard. Mineral

rejection/waste will also be handled mechanically; in the quarry the road will be maintained

with 1 in 16 gradients. Sufficient number of bunds and parapet walls will be constructed all


along the quarry haulage roads, wherever necessary in order to maintain safe working

conditions, by availing the waste generated during the course of quarry operations.

Year wise development and production proposed for five years are presented in the table below.

The approach roads are shown in the production and development plan. The year wise details

are enclosed in the annexure.

c) Indicate proposed rate of production: The proposed present rate of Building Stone saleable

production is average 20439 tonns per annum. It is proposed to work by Semi-Mechanized

method of quarrying. On this basis and considering the total reserves of 257166 tons of mineable

reserves, the anticipated life the quarry, works out to about 5 years subject to further

exploration results anticipated from the first plan period and the subsequent re-assessment.

d) Conceptual quarry plan for the entire lease area: The entire strike length of the deposit is

exposed & the quarry is envisaged to be worked forming benches. The ultimate pit limit is

marked as shown on the Geological plan pls ref plate no 5 &6. However, when the Building Stone

is proved to its full depth, the conceptual plan will be duly modified. The possibility of Building

Stone below is to be examined further by exploration.

The Quarrying is proposed to be taken up with the capacity of Development & Production of

ROM of about 20439 tonnes of Building stone till the End of Quarry Lease period. Before the lease

period completed applicant to apply for renewal to continuation of the quarrying activity in the

same area. Any modifications in the quantum of production will be intimated & details will be

furnished to Department of Mines & Geology. The successive advancement of the pit at the end is

depicted in the Conceptual Mining Plan vide Plate No 01. The design and layout of the quarry

benches is shown on the above referred relevant plan. During the conceptual plan period the

anticipated production levels of Building Stone for the next 5 years period will be 102197 tonnes

Building Stone. The quantity of waste/mining losses generated is very less and the same shall be

utilized for formation of safety bunds, road leveling work to fill pot holes etc.

The working results obtained during the present plan period and the data generated by working

the mineral deposit will be taken into consideration and accordingly exploration programm if

required will be charted out for re-assessment of the mineral reserves at the end of the fifth year

as there is enough reserves till the end of the fifth year which will be helpful to carry out

production during the first scheme period. The result of the same will also be thus helpful for

further modifications of the Conceptual plan. The guidelines of state Government i.e. DMG will be


followed during the conceptual period in respect of mineral Conservation & Environmental

Management Plan. The quantity of waste/mining losses generated is very less & the same shall

be utilized for formation of safety bunds, road leveling work to fill pot holes etc.

material, for roads metal, slabs, and scrub stones & for drainages. Infrastructure related

activities and increase in residential and middle income housing projects in the close vicinity

have contributed to the demand of the aggregate materials.

9) Crusher Process Methodology: Crusher machinery is used for mining, stone quarries, and

making and aggregates of different levels of hardness. The crushing though done for centuries

now has very efficient designs, the basic lay out involves a ground level hopper to which the

quarried stone is discharged and form a series of apron and curtain feeders, it is passed on to a

heavy perforated sieve like structure and separate different sized stones. The undersized are

sent to the secondary crusher.

10) Other: A Quarry Site office with Rest shelter, First aid room is located towards Western side

of the quarry lease. Packaged drinking water will be provided from a market to the Quarry office.

Site services: The site services exiting within the lease area are: Office shed, First aid station

with in the office shed, Canteen, Drinking water shed and Rest Shelter. All other required site

services is proposed during the five years Quarrying plan.

a) Employment potential:

01. Labors for Production of work -6 Unskilled

02. Labors for Production work -2 Semi Skilled

03. Labor for Quarrying-About 6 Un-Skilled

Note: Appointments of experienced & qualified statutory staff shall be in accordance with rules

and necessary permission shall be obtain for exemption if any or appointments on part time

bases based on the small scale production activities.

11) MINERAL PROCESSING: There is no beneficiation or processing plant at the quarry site.

Building Stone ROM will be manually / mechanically broken & sorted separately and marketed

as per the buyer specification. The specification generally are required for road metal is +10mm

and above.


PART-B

12) ENVIRONMENTAL MANAGEMENT PLAN

a) STATUS OF BASELINE INFORMATION

i) Land use pattern: The quarry lease area falls in Govt. Gomala land. The area is

covered by rocky exposures and the creeks with tiny bushes and shrubs. The lease

area is proposed to be utilized for quarrying and except for quarrying the land is not

used for any other purpose. Proposed buffer zone in the lease area, leasee will be

maintaining when quarry area reached to ground surface. The details of the

utilization of the proposed area and for next five years are as follows:

PROPOSED LAND USE PLAN FOR NEXT FIVE YEARS:

Sl No Proposed Land Use Area (In Acres.guntas)

01 Quarry working area 0-16 02 Waste dumps 0-02 03 Roads 0-02 04 Infrastructure 0-06 05 Mineral Storage 0-00 06 Proposed Buffer zone 0-14 01 Undisturbed area 0-00

Total 1.00

ii) Water Regime: There is no perennial stream or a spring in the area and the ground water

level lies far below in the valley outside the quarry lease area. The nallas flow towards the slopes

in the area as shown on Plate-8. These will have water only during monsoon period. The water

table is 80-100 m below the general ground level and the quarrying operations will not affect the

water regime.

iii) Flora and Fauna: Due to rocky exposures on the surface of the area, except for shrubs-

bushes, there is no other vegetation in the lease area. The buffer zone outside consist of forests,

agricultural lands etc., There is no wild life in and around close by vicinity of the area.

iv) Quality of Air, Ambient Noise Level and Water: Quality of air is normal and there is no

cause for any pollution of air in the area but manual / mechanically loading jack hammer drilling,

rock breaker, shovel working and truck transportation generate air pollution in the form of dust


which will be controlled using water sprinklers. Ambient noise level is far below the threshold

value, as the area is calm and no human settlement around 1 to 1.8 km radius from the Quarry

lease area. There is no source of water in the area. The water for use at mines will have to be

transported from the private land borehole water located near by the quarry lease area.

v) Climatic Conditions: The area can be described as semi-arid zone, the maximum

temperature of about 36 deg Celsius as March-2014 and minimum temperature of 15 deg Celsius

as recorded January 2014. Rainfall is scanty (about 1132 mm during previous year 2013) and

confined to monsoon period only. In general the area is drought prone.

vi) Human Settlements: There is no human habitation in around 0.5 kms radius from the area.

The nearest village is Mayasandra Village, Kundana Hobali located about 1.1 Km west of the

Quarry site.

Villages and Population of Surrounding Area:

Sl.No Village Name Distance Km Direction Population

1 Muddanayakanahalli 1.48 SE 548

2 Thylagere 2.01 NE 599

3 Mishiganahalli 1.54 N NA

4 Mayasandra 1.1 W 333

5 Chikka Golahalli 2.0 SW 735

6 Byadarahalli 2.95 S 969

7 Kodagurki 3.3 E 1069

vii) Public Buildings: There are no public buildings, monuments or wild life parks in and

around the adjacent vicinity of lease area. The lessee should construct retaining walls and check

dams to avoid surface run off to agricultural lands. There are no open wells or bore wells within

the vicinity of quarrying block. The proposed quarrying area is also situated at an elevation of

about 181 m from the surrounding area. As such it is presumed that the water table is not going

to be affected. Noise levels should be kept within permissible limits. Sri Shankarappa will

approach the concerned authorities for their consent, if necessary.

b) Environmental Impact Assessment Statement:

i) The Quarry lease area (core zone) has been proposed for medium scale activities, for the next

five years quarry working shall prevail in the quarry area and around the leasehold area. There


are no adverse changes on the land environment. Most of the surrounding area in the western

and eastern zone will still remain virgin with natural vegetation & topography.

Proposed Five year plan period land use pattern as follows



Total 1.00

The quarry / mining activity will not affect any public buildings, monuments of archaeological

Importance, as none exist in the vicinity of the proposed quarrying block.

ii) Air Quality: Quarrying operations of Building Stones involve jack hammer drilling and

controlled blasting. Use of machinery for excavation & loading of mined minerals, is a major

contributor for affecting the air quality. Loading and transport of minerals generate some small

quantities of dust, which again depend on factors such as the topography, nature of material

handled and climatological parameters like wind speed, wind direction and stability

classification of the area viz. Location of buffer zone villages. The quantum of quarrying

operations is very limited (only ROM 20439 tons maximum per annum) with crushing and

screening undertaken as per Crusher Act and Rules. And hence there shall not be regular fugitive

emissions. However, care will be taken to suppress dust by sprinkling water at all loading places,

mineral dressing/ stock yards etc.,

ii) Water Quality: Surface water: There are very few small nallahs existing near by the quarry

lease, which are of seasonal nature. Precautions will be to taken to avoid the wash-off from

quarry to nearby nallahs by construction of Check dams, Gully plugs & retaining walls.

iii) Noise Level: The noise level of the core and buffer zone is expected to be within the

permissible limits. Quarrying activity is likely to increase the noise at the loading points and jack

hammer drilling locations. However since the workers will not be expected to be high levels of


noise for considerable period of time, no extra precaution is proposed. The workers shall be

provided with ear plugs/muffs and nose masks.

iv) Vibration Levels (Due to Blasting): Since drilling and working of quarry with medium

scale earth moving machinery is proposed, the impact on ground vibration levels shall be

insignificant and level of vibration of machinery by working will be within the permissible limit.

Use of explosives shall be restricted to the minimum possible by use of hydraulic rock breaker

and controlled blasting methodology.

v) Water regime: The existing seasonal nallahs in the buffer zone remain dry and becomes

active during rainy day. Since the water courses are shallow and workings are situated at higher

elevations, water will not pose any problem. Since rain fall is comparatively high, sufficient check

dams and retaining walls shall be constructed; there will not be much siltation or run-off

problems. However, proper precautionary measures will be taken up to avoid any impact on

water regime, The requirement of water at the quarry site is for domestic consumption /

drinking only ; water is not intended to be used for purposes of mineral beneficiation or washing

etc..

vi) Occupational Health and Safety: Main occupation of the local people is agriculture and

quarrying related activities etc. Lately many of them have found more rewarding jobs in the

quarrying sector. Further safety shoes, helmets, goggles, leather gloves, earmuffs, breathing

mask etc will be provided to all the eligible workers as per the prescribed norms set by Director

General of Mines safety.

Vii) Historical Monuments etc.: There are no historical monuments or place of importance

located within 5 km radius.

ENVIRONMENTAL MANAGEMENT PLAN:

(i) Temporary Storage and Utilization of Top Soil: We would at the very outset wish to state that

we are very much interested in afforestation programs. As the quarrying is confined to the slopes

of the hills in the quarry block, and the topsoil on the slopes is less than 1-3 m in thickness that


too in small patches, the question of destroying the topsoil does not arise. Whatever available the

topsoil seen in the area will be carefully taken out for afforestation purpose.

(ii) Reclamation Proposal: During the first five years it is proposed to quarry the Building Stone in

a large scale. The overburden if any that would accumulate in the proposed quarrying will also is

stocked separately. This will be used to fill up pits likely to occur in the future to bring back the

surface as far as possible to the original topography. However as the quarrying area is a hilly

tract and the Building Stone is confined to the ridges and slopes the question of filling up of pits

does not arise. The structures such as shelter will be removed and the land restored as possible

to its original condition.

(iii) Programme of Afforestation: It is proposed to develop a green belt inside and outside the lease

area. In addition, the place around the haul road outside the lease area after obtaining necessary

permissions from concerned authorities. Every year it is proposed to carry out afforestation by

Planting 150 saplings per annum within and outside the lease area. Proper care will be taken for

protection and growth of these samplings. The bio-fuel local sapling varieties like Honge, Neem

and Badam etc. will be grown. The details of the afforestation program are as given below:

Table: Afforestation program for the five year plan

Year No’s Survival Saplings First 100

15% Bio-Fuel plants like

Honge, Neem, Badam etc.,

Second 100 Third 100

Fourth 100 Fifth 100 Total 500

(iv) Stabilization and Vegetation of Dumps: There are no existing old dumps so stabilization and

vegetation of dumps doesn’t arise. The quantity of waste/mining losses generated is very less &

the same shall be utilized for formation of safety bunds, road leveling work to fill pot holes etc,.

(v) Treatment and disposal of water from the mine: As explained above, there are no water

sources in and around the quarry block. The quarry lease area is also situated in a mound/hilly

tract with the first five years of quarrying confined to the Building Stone within the pit.


Therefore, there is no possibility of accumulation of water in the pit and treatment and disposal

of water from the quarry does not arise.

(vi) Measures for Minimizing Adverse Effects in water Regime Water regime in the area will not

be affected as explained above.

(vii) Protective Measures for Ground Vibration/Air Blast Caused by Blasting: For the first five

years, production will be by using jackhammer of small diameter. Drills for blasting are

necessary in the proposed quarrying. Therefore, the vibration caused by blasting is negligible as

controlled blasting techniques will be followed.

(viii) Socio-Economic Benefits Arising out of Mining: This Semi-mechanized Quarrying proposal

will bring continuous employment of labors from nearby villages. Otherwise they are fully

dependent on agriculture and quarrying lease. About 21 direct employments and other fifty

indirect employments will be generated. Thereby economic condition of the local people shall

improve.

Mine description: The quarry lease area is located at a distance of 35 km from Bangalore Rural 3. GEOLOGY AND EXPLORATION: Already discussed in part A please ref page number 5-9

3.1 Indicate mineable reserves by slice plan / level plan method: The slice plan/level plan

required as per the proposed quarrying parameters is indicated in annual production plan &

the scale of quarrying operation is medium Semi-Mechanized Method.

3.2 Mining method: The quarry is proposed to be operated by semi-mechanized opencast

mining.

3.3 Abstract of the proposals for protection of environment: Temporary storage and

utilizations of top soil: as per the proposed quarrying programme over next five balance years,

the top soil quantity generated is very less. However, any small quantity if generated will be

stacked and used for afforestation purposes.


3.4 Year wise proposal for reclamation: Since building stone deposits are likely to continue,

concurrent reclamation is not feasible and after working pits are exhausted, than concurrent

backfilling will be proposed. The mined out areas as shown in the relevant year wise production

and development plans will be not matured enough for reclamations. Hence, the backfilling on

worked out pits for reclamation programme is not envisaged presently. Suitable afforestation

techniques will be adopted for reclamation after winning of the mineral. Proper fencing will be

providing all around to prevent accidental falling of animals and human trespassing to the

worked pits. The details of protective measures mentioned above are shown on the

environmental plan.

3.5 Afforestation programme: It is proposed to develop a green belt inside and outside the

lease area. In addition, the place around the haul road outside the lease area after obtaining

necessary permissions from concerned authorities, every year it is proposed to carry out

afforestation by plant in 100 samplings per annum. The species chosen for green belt are fast

growing with good canopy and dense leaf density, eco-friendly commercial spices and some

ornamental plants to give good aesthetic look.

3.6 Stabilization of the dumps: The generation of overburden and waste during the proposed

quarrying plan period will be waste (voids and mineral losses) 2044 tons of building stone.

There is no requirement for storage of waste as it will be utilized for leveling of roads and

maintenance.

3.1 Measure to control erosion/sedimentation of water courses: the existing watercourses

shall not be disturbed and rain water will continue to flow in the same direction. Sufficient check

dams would be constructed in the drainage nallas so as to arrest the surface run – off. The details

as discussed in the chapter of environmental management plan.

3.8 Treatment and disposal of water from mine: since there are no mine water or ground

water, the proposal of pumping out or any sort of treatment and disposal of water from the

quarry does not arise. Measures for minimizing adverse effects on water regime: watercourses

shall not be disturbed and rain water will continue to flow in the same direction as it is in

existence. Since the water is not withdrawn for quarrying purposes or the water is pumped out

during the quarrying operations no adverse impact is foreseen on the existing water regime.


3.9 Measure for protecting historical monuments and for rehabilitation of the habitat: No

historical monuments are located within 5kms distance and hence need of protecting does not

arise.

4 CLOSURE PLAN:

4.1 Mined out land: The present worked out area of since the remaining lease area building

stone deposit continues further, there is no reclamation of the mined out areas during the

present proposed plan period due to persistence of deposit further and it is envisaged to take up

reclamation only after cessation of the quarrying activates i.e after full exploitation of the

deposit. If there is any temporary discontinuance of the quarry, the applicant will take

appropriate measures to restrict access to un authorized entry, provide protective measures and

fence the quarry opening or workings and all other structures. It shall also be ensured that the

quarry working and all other structures it shall also ensure that the quarry workings overburden

dumps stock piles and other structures if any will be maintained in stable and safe conditions.

The proposed area to be worked during the first five years is shown in the year wise production

and development plans. Only reclamation by way of afforestation and open place outside the

lease area, are proposed. Quarrying activity once reach the blow the surface level shall be

periodically reclaimed as discussed by backfilling in future and made suitable for agriculture or

as creating a water body / reservoir.

4.2 Water quality management: Water quality is good because there is no source of pollution

due to building stone quarry.

4.3 Air quality management Dust generated by this quarrying activity is quit less. The major

source of air pollution is due jack hammer drilling activity, rock breaker operations and loading

of building stone and overburden / waste the management of air quality shall be by suppression

of dust by water sprinkling on haulage road s and wet drilling methods. Also In the vicinity of the

area no major industries are seen and the deposit is worried on a very small scale.


4.4 Noise level and vibration: No deep hole drilling and blasting activity involved in quarrying

operation except small dia jack hammer drilling is proposed. Protective ear muffs, nose masks

and hand grouse, safety shoes etc are provided to reduce the effect of sound/ noise and

vibrations for the drill operators

4.5 Waste management: the generation of waste material is very less from this quarry and the

same is utilized for afforestation.

4.6 Infrastructure: Besides during 1st five year plan period there is no proposal for initiating

closure operation. There will not be much infrastructure in the area which is required to be

attended. The lease area presently does not have any public roads; railways lines, telephone

lines, public buildings etc. Regular monitoring and maintenance of the existing infrastructural

facilities such as roads buildings and structures transport etc. will be done.

4.1 Disposal of quarrying machinery: There is no proposal of disposal of quarrying

machineries during the present plan period.

4.8 Safety and security: The applicant will follow prevailing mines act Karnataka minor mineral

concession rules and regulations etc. as well as other directions given to him time to time by

directorate general of mines safety. The applicant will securely fence the excavated area by

barbed wire of height to prevent the free access and unauthorized people to the quarrying area.

The applicant will appoint security personae to ensure to prevent unauthorized entry on weekly

off days, festival days and during the time of discontinuance of quarrying operation.

4.9 Disaster management of risk assessment: All the safety measures during this quarrying

will be taken as per the norms of DGMS. Safety of the men and machine are most important

during this quarrying activity. No danger to public life and property arises as only trucks pay

form quarry site through public road. There is no water impoundment s at higher levels or at

loser contours.

it is into applicable at this stage, however few salient features to some extent is briefed below

Number of local residents employed in the quarry, status of the continuation of family

occupation and scope of joining the occupation back. The local employed are about 15 % those

who are directly employed they are basically from agriculture back ground, they will be part

back to their original occupation. Necessary counseling will be taken care. Compensation given

or be given to the employees connecting with sustenance of himself and their family members.

Compensation as provided in the statue will be given at the time of final quarry closure to the

eligible persons.

Satellite occupation connected to the quarrying industry number of person’s engaged therein

continuance of such business after quarry closes Most of the satellite occupations are not fully

deepening upon the quarrying activity or closure of mines and the quarrying operations is

medium scale. So the occupations like workshops hotel and tea shops will not affect continuance

their business continued engagement of employees in the rehabilitate status of quarrying lease

area and any other supporting activities. Security and essential service people will continue to be

employed for purely short term/ temporary basis. Where operations are discounted for longer

period, it is not continue with their employment and so these will be reduced to minimum;

counseling will be provided for their rehabilitation. Envisaged repercussions on the expectation

of the society around due to closure of mine quarry. There will be effect on their economy;

Communication. Transportation to some extent- but still manageable to large extent. Details will

be given in the final quarry closure plan.

8. Time scheduling for abandonment: The present plan prepared is a progressive quarry

closure plan indicating the reclamation and rehabilitation measures being taken up

simultaneously with the quarrying operations no abandonment of quarrying activates is

envisaged. The manpower rand other resources for implementing the protective and

rehabilitation measures will be dealt in detail in the quarry closure plan to be prepared for

approach before the abandonment of the quarry. The details of afforestation inside and outside

the quarrying lease area, reclamation and rehabilitation environmental monitoring details

machinery performance and socio economic impact of quarrying shall be regular monitored and

furnished to DMG. Records of the same shall also be maintained.

9. Any other relevant information: The production of building stone shall be enhanced if any

need or required areas due to change in the market scenario accordingly and modification in the

method of quarrying will be submitted. The reserves will be re estimate and furnished after

completed of the proposed exploration activities in the leasehold area this will be intimated and

prior approval and guidance of DMG will be obtained.


10. CONCLUSION: Geological survey and detailed mapping was carried out in the Government

Gomala land in respect of notified area of Sri Shankarappa, for extracting building stone in Part

of Sy. No. 110 covering an extent of 1 Acre in Thylagere Village, Kundana Hobli, Davanahalli

Taluk, Bangalore Rural district. The study revealed the occurrence of building stone material in

the leased area and shall be carried out adapting standard procedures. Based on the present

quarrying data and quarrying activities in the adjoining lease area, a geological reserve 601884

tonnes of building stone material is estimated; of which economical minable reserves of 257166

tonnes is computed. Therefore/hence this area is recommended for building stone production of

20439 tonnes/Annum & salable production of 20031tonnes/Annum.
