2.2 Brief Information about the Project

The mining lease area of 19.80 ha is located in Government land, near

Girimapur Village, Medchal Mandal, Ranga Reddy district, Telangana.

It has been proposed to produce approximately 9,00,000 TPA of Stone

& Metal.

Mining:

The mining operations are proposed to be carried out by opencast

semi-mechanized method. Stone & Metal is exposed on the surface.

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

In the context of depleting natural sand resources in many parts of

the world due to sterilisation of reserves and environmental concerns,

concrete producers, construction engineers, builders and suppliers of

sand are of the firm view that crushed stone sand is a substitute to

natural river sand.

2.4 Demands-Supply Gap

The use of the crushed stone sand although not new was at one time

negligible as the natural river sand was abundantly available. But now

the situation has changed. The quantum of fine aggregate available is

same but the requirement of natural sand increased several hundreds

of times since 1970. The government and the construction industry

feels that to meet the ever increasing demand for the fine aggregate

there is no other alternative except going for crushed stone sand.

Crushed stone, one of the most accessible natural resources, is a major

basic raw material used for construction. For centuries crushed stone

coarse aggregates were being used for the production of various types of

concrete in construction.


2.6 Employment Generation

Proposed mining is semi-mechanized method and this project operation

will provide livelihood to the 30 workers. It will provide employment to

the people residing in vicinity.

3.0 PROJECT DESCRIPTION

Village, Medchal Mandal, Ranga Reddy district, Telangana. The

mining lease area falls in Survey of India

3.3 Details of Alternate Sites

No alternate site was considered as the project is mineral specific and

site specific.

3.4 Size or magnitude of operation

The proposed mine has lease over an area of 19.80 ha and the

production rate is 9,00,000 TPA.

3.5 Geology and Reserves

3.5.1 Regional Geology

The quarry lease area constitutes a part of Granite and Granitic Gneissic

terrain of Archean age. Pink and Grey Coloured Granites, Pink Alkali -

Feldspar Granites are the important litho units in the area. Grano –

Diorites with basic enclaves of Supra - Crystals like Horneblende Schists,

Biotite Schists also occupy the area. These rock types are exhibiting

various landforms like Domes, Inselbergs, Castle - Koppies, Whalebacks

and Linear Ridges.

Pink Alkali Feldspar is the most dominant rock type in the area with

variations in grain size, scattered outcrops of Migmatites containing

Neosomes of medium to Coarse - Grained Grey Alkali Feldspar Granites

occurs at many places. A number of Quartz, Grey and Pink Pegmatites

and Epidote Veins Criss crossing the host rock. Basic dykes of Dolerite,

Gabbro & Pyroxenitic Composition traverse the granites in NW-SE, NNW-

SSE, E-W & NE-SW directions. Thin veneer of alluvium is found limited

to streams.

3.5.2 Local Geology

Entire quarry lease area is covered with colour granite which is rising up

to 25M above ground level trending E-W, the strike length of the

formation measured 500M in the area with an average width of 175M


BRIEF DESCRIPTION OF LITHO UNITS:

a) Texture and Grain size : Texturally the rock in the lease area is

Porphyritic Texture with fine to medium grained.

b) Colour and aesthetic beauty of the stone: The rock is light black with

green shade. The rock is aesthetically good looking.

c) Hardness :Mohr’s Scale : 6 – 7

d) Mineralogical composition :

The main litho unit is Dolerite Mineralogical the Black Granite

consists of Pyroxene and Plagioclase feldspar as essential mineral and

other mafic Biotite, Mica, hornblende, etc., as accessory mineral with

fine to medium grain. The mafic minerals are observed in more

content hence the rock is melaocratic. The Granite available in the

demarcated area is useful for Granite Cutting and polishing purpose.

e) Density /specific gravity: 2.776 g/cm3

f) Water absorption capacity: 0.138 % (kg/cm2)

g) Porosity: 0.36

h) Compression strength: 687kg/cm2 (in dry state)

i) Abrasiveness: 6 - 7

j) Permeability: Negligible

k) Rock Quality designation: The Rock Quality designation is

estimated to be good with RQD % between 84 and 95.

l) Young modulus of elasticity : 7 725 (105 kg/ cm2)

m) Degree of weathering under Hand lenses/Microscope: Fresh rock

surface is un-weathered and it is categorized as Grade 'A'.

n) Glossiness: The rock takes good polishing.

The Granite available in the demarcated area is useful for

Granite Cutting and Polishing purpose.

3.6 PROJECT DESCRIPTION WITH PROCESS DETAILS

3.6.1 Method of Mining

Mining will be carried out by opencast semi mechanized mining

method. Overburden will be (weathered rock portion) is removed by

line drilling.


Drilling will be done with compressors and jack hammers. Excavators,

cranes, chain-pulley blocks and winch will be used for dislodging

lifting and loading the blocks.

The dislodged blocks from the sheet rock will be dressed by chisel

men to the maximum possible size and then loaded by cranes or

chain-pulley block or winch into the trucks for dispatch to the

destination.

The following machinery is being deployed in the leasehold area to

carry out the mining operations:

along the mining lease area and will be backfilled into the minedout

pit at the end of the mining.


7 REHABILITATION AND RESETTLEMENT (R&R) PLAN

Not Applicable.

8 PROJECT SCHEDULE & COST ESTIMATES

The Total cost of project would be around Rs. 70 lakhs.

9.0 ANALYSIS OF PROPOSAL (FINAL RECOMMENDATIONS)

9.1 Financial and Social Benefits with Special Emphasis on the

Benefit to the Local People Including Tribal Population, If Any, In

the Area.

Although granite is a minor mineral, it is a major contributor in

foreign exchange earnings. India is the second largest exporter of raw

granite after China and ahead of Brazil and South Africa.

This project will also provide employment to local people helping them

earn livelihood.
