3.5 Geology and Reserves

3.5.1 Regional Geological set up

The Geological formations in the Chittoor (Dist) can broadly be divided in two 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 Gudipala block. The remaining parts of District is Occupied by Archean rocks 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 Litho logy Recent Alluvium Pleistocene Laterite ---------------------------------Unconformity-----------------------------------------

Younger intrusive, epidote veins, quartz veins and reefs. Pegmatite’s veins of Alkali Feldspar granite and syenite Dolerite / Gabbro / Basalt dykes Leuco Granite. Nebulitic to homophonous biotite granite

Peninsular gneissic complex (Migmatite group)

Nebulitic to homophonous Hornblende Granite and Leuco Hornblende granite

Archeans Biotite Granite Gneiss, Hornblende Granite Gneiss, Porphyritic Hornblende Granite.

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

3.5.3 Exploration a) Present Status:

It is a newly applied Quarry. The Preliminary survey has been done. The Q.L

applied area does not contain any forest cover. The area does not consist any

wild life.

b) Future Programme

The applicant wishes to take up following steps towards future program:

1) Continue and conduct regular quarrying operations in systematic manner and

intensify production of Black granite blocks along N-S direction

2) Conduct the prospecting operations simultaneously at various places to study

the behavior pattern of the black granite and the textural and color variations

based on the study suitable decision relating to commencement of exploratory

mining.

3) Locate other suitable buyers of local, inland abroad.

4) Develop afforestation in 7.5mts buffer zone all around the lease area by filing

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 : ( Proposed 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 :

There is no overburden on the deposit. Boulders are exposed on top of the

Black granite. The South-West side of the area is selected for dump yard for

next five years and the waste will be stocked in the dump yard. Step dumping

will be resorted. This material can be utilized to fill the pits after quarry



operations are over. When the dumps reach their optimum height suitable

greenery will be grown on these dumps to stabilize them.

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.

1. Once the free face is developed in working place, the primary cuts are

taken up over a maximum length of 10 mtrs to a width of 3 mtrs and to

a depth of 6 mts 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.

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

involve drilling and blasting.

3. The holes are charged with low explosive cartridge like gun powder

and non-delay detonators for smooth blasting.

4. 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.

5. 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:

i. Once the primary blocks are dislodged from sheet rock depending up

on the dislodged material secondary blocks are cut, fractures, block

lines and penetrative cracks are carefully trimmed and removed b this

way.

ii. The commercial blocks will be trimmed so as that the sites form right

angles to each other



iii. The applicant has been proposed to size of blocks could be formed

from the ROM of this property will be in the following direction ranges in

Gang saw as well as cutter sizes.

Gang-saw sizes Cutter sizes

Length : 190 to 270 cm 90 to 180 cm

Width : 140 to 200 cm 60 to 90 cm

Height : 120 to 170 cm 40 to 70 cm

f) Production of Commercial Blocks:-

Major boulders exposed are used for small size marketable 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 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.
