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.

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/cm 3 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 (10 5 kg/ cm 2 ) 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: Mining Machinery S. Machinery No.s No. 1. Excavator (Tata Hitachi 45 Lc) 2 2 Tipper (Leyland 17 tonnes) 3 3. Compressors (CFM-50) 1 4. Jack Hammers 4 Minor tools : Chisels, crowbars, pick of axes spades and hammers of different sizes. 3.7 Raw Material Required Along With Estimated Quantity, Likely Source, Marketing Area of Final Product/S, Mode of Transport of Raw Material and Finished Product No raw material will be required in the proposed project. The operation involves the extraction of black granite and dumping in stock yard. The dressed dimensional granite will be transported through hired trucks to the granite market or sea port.
3.7.1 Use of Mineral 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.
