2.3 Need for the Project and Its Importance to the Country or Region

The demand for granite increased due to rapid industrialization and growth in

infrastructure. So the number of granite producing quarries is increasing in

India. Granite is the chief material for the export industries like monuments,

flooring slabs, Kitchen articles, sculptures & export. Based on the demand of

Granite, the lessee intends to produce the required quantity of Black Granite for

domestic market.

As per EIA notification 2006 the project falls under Category- B, the proponent is

submitting the proposal to get Clearance for production capacity of 260 m3/

annum of granite blocks from SEAC, SEIAA, A.P for the purpose of grant of quarry

lease.

2.4 Demands-Supply Gap

The demand and supply for the Black granite is growing which makes a lot of

scope for revenue generation. Once the stone is obtained after quarrying it is

further processed and supplied to industries.

India is amongst the leading exporter countries of stones in the world. The major

importers of Indian stones are USA, China, UK, Italy, Belgium, Germany, UAE,

Hong Kong, Spain, Taiwan, Netherlands, Canada, Turkey, France, Russia and CIS

countries. The growth is continuing and the demand for marble, granite,

sandstone and other dimensional stones and stone products is anticipated to

grow at around 15% CAGR.

3.5.1 Regional Geological setup

The Geological formations in the Chittoor District can broadly be divided in distinct and

well marked groups and older group of Metamorphic rocks belonging to Archean and

Younger group of Sedimentary rocks belonging to the Proterozoic age the later cover

part of Punganur block. The remaining parts of District is Occupied by Archean rocks


10

which consist of Schist, Gneisses, Quartz veins and basic dykes. The Archean rocks have

suffered considerable degree of tectonic disturbances, as a result of which the rocks

have been metamorphosed and recrystallized.

Stratigraphic Sequences established in the area as follows:

Geological age Lithology

Recent Alluvium

Pleistocene Younger Intrusive, Epidote Veins

Quartz veins and reefs .

3.5.2 Local Geology

The Black Granite in the Distinct form of occurrence as dolerite dyke swarms in either side of the Grey granites & Gneisses. The Subject area belongs to a hillock extended in EW direction and gently sloping towards South direction with Black Granite Sheet Rock intruded as Dolerite dyke. The rock is highly puckered, sheared and faulted and has schistosity trending between EW with moderate to steep dips in either southerly and Westerly directions. The peninsular gneissic complex comprises gneisses (migmatite), gray granite, and Pink Granite and Gneissic granite. The gneiss in general show banding due to alteration of light colored quartzo- feldspathic minerals and dark colored biotite or hornblende minerals. These rocks may be separated in to two distinct groups namely the massive foliated types occur as low dome shaped hillocks. The intrusive relationship of the granite rock is evident by the presence of tongues and


11

apophyges within the older rocks and the occurrence of xenoliths of the older rocks within the granite.

3.6 PROJECT DESCRIPTION WITH PROCESS DETAILS

3.6.1 Method of Mining

a) Type of Mining:

Open cast method of mining is carried out in this mine by manually and semi

mechanization by using compressor operated jack hammer drills, excavators, and

dumper etc, Transportation will be made by trucks to dispatching point.

b) Brief Description: (Existing method of working)

The mining operations are carried out by semi-mechanization as open cast mining.

Hydraulic excavator and compresses operated jack hammers were used for cutting the

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

low explosives to avoid feather cracks.

c) Removal / Excavation of O.B. and other Quarry Waste:

The middle of Northern side of the Q.L.area is selected for dump yard for next five years

and the waste will be stocked over a length of 60mts, width of 40 mts, to a height of 8

mts as a earmarked in plate No.4. Step dumping will be resorted. This material can be

utilized to fill the pits after quarry operations are over. When dumps reach their

optimum height suitable greenery will be grown on these dumps to stabilize them.


13

d) Separation of large primary Blocks from the mother rock by pre-splitting

(Primary):

The mining will be followed in the form of linear cut method. This involves loosing of

the primary block from mother rock. Hence primary cutting will be done by line drilling

method where close spaced parallel holes along straight line will be made. Line drilling

method is used for separation of primary blocks.

i. Once the free face is developed in working place, the primary cuts are taken up

over a maximum length of 10m to a width of 3m and to a depth of 6m depends

upon the joints availability. These dimensions are confirmed as for field studies.

Primary block will be cut into secondary blocks by Jackhammer drilling and

wedge cutting and this block will be dislodged from in-situ position by an

excavator.

ii. Line drilling method will be used for cutting the primary blocks which involve

drilling and blasting.

iii. The holes are charged with low explosive cartridge like gun powder and non-

delay detonators for smooth blasting.

iv. The use of delay detonates causes fragmentation and cracks in rocks. The non

detonating cords are inserted into the holes and the holes are stemmed with

muck and plugged at the mouth and fired.

v. Thus the block will separate from the mother rock, which is pulled off from the

face with cranes or shovel.

e) Sub-Division of large Primary Blocks into Secondary Block:

This will be done drilling close spaced holes (along a line) down to the depth and the

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

Close spaced holes will be drilled to the half the length of the block on either side of

it by using wedges blocks can be separated.

f) Production of Commercial Blocks:-

After primary separation the rock mass will be carefully examined to avoid hair line

cracks, mineral segregations and veins etc., The dressing of the rough blocks will be


14

made by chipping the edges and geometrically equating the edges of the block at the

dressing yard. The rough blocks obtained after primary cut it will be dressed for

obtained good geometric shape of granite. Thus the commercial blocks are produced.
