Education Facilities are available in Kalwala Village and elementary school education is available at Kalwala village. Hospital facility is available at Jammikunta, which is 11.25 km SE direction from the lease area. Power connections and Telecommunication facilities are available at Kalwala village. 4 Sri Sai Manasa Nature Tech Pvt. Ltd. Topographical map showing 10 km radius is given as Fig-1, 5 Sri Sai Manasa Nature Tech Pvt. Ltd. 1.5 Topography: Geology: The region forms part of Archean Peninsular Geniessic complex consisting of granites and Gneisses traversed by granitoids and veins of quartz and epiodote. Granites are leucocratic to mesocratic. Comercially called as grey, pink, & white types of granites. a. Brief Description of Topography: The quarry lease area is on a top level surface of a minor elevated terrain at an altitude of about 321 m above mean sea level. The north boundary follows the path at counter elevation is about 321 m & 2 km radius of study area contour elevation difference is 20 m msl. The area is Pedi mount - pediment complex & diagonal minor lineaments which is lineament at N-S & W-E directions. The area is generally N-S high ground almost the area slopes towards North West to East. The major drainage course is flowing towards South to North & West to East towards Godavari river 7 major drainage patterns around drainage course is first order, having well defined courses traversing continuously with scattered cultivated agricultural fields. b. Regional Geology: Geological Settings: The area is part of the stable Southern Indian Peninsular Gneissic Complex (PGC) of Achaean age. The PGC occupies a major part of the Granites, Grano-Diorite are exposed in a massive spread in the study area. The PGC are intruded by basic dykes & Quartz Pegmatite Gneisses (QPG). c. Local Geology: The Quarry Lease area comprises of alluvial soil covering the entire Quarry lease applied area with granite rock outcropping here and there. But most of the subject area is covered by the alluvial soil of 1m to 7m followed by massive sheet formation, as seen in the adjacent Granite Quarries. This rock type m been derived from migmatization of different rock types. Topographically the QL applied area is general the area is plain studded with isolating hillocks. Sometimes they may raise gently as continuous hills, presenting a rugged topography. 6 Sri Sai Manasa Nature Tech Pvt. Ltd. The Granitic blocks are designed such way as per marketable sizes 6*4*3 m & smaller 1*1*0.5 m in the area. The litho unit of the area is follows: Soil cover : Loose reddish brown with mixture of sand. Gneissic Porphyry Granite : Ripples multi-colour granite. Light pink granite (Brown colour) gneiss : Alkali Feldspar rich magmatic sand. Microscopy: Detailed microscopic examination of thin section of representative sample of subject quarry lease area. Under microscope the average minerals constitutes or composition is as given below. Orthoclase feldspar 55% Quartz 17% Biotite 13% K-felspar 8% Hornblende 7% (Source: Mining plan) Exploration/Prospecting 1) Present Status: It is a new Quarry. The Preliminary survey has been done. The applied area does not contain any forest cover. The area does not consist any wild life. b) Future Programme The proponent wishes to take up following steps towards future program: 1) Continue to 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 color 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 7.5m buffer zone all around the lease area by filing up the area with solid waste to support the vegetation on the barren rock zone. 5) To maintain safe distance as per mining laws to the public structures adjacent to the leased area. 7 Sri Sai Manasa Nature Tech Pvt. Ltd. 1.7 Reserves The details of reserves of mine are given in Table 1.2 Table 1.2 Reserves of Mine Reserves @ Category 20% in m³ Proved 6,86,700 Probable 4,97,800 Possible 4,93,300 Total 16,77,800 (Source: Mining plan) Life of Mine: The total quantity of mineable reserves is considered as marketable reserves. Total mineable 10,69,550 m3 reserves of available in the lease. The proposed production is 36,000 m3 per year. Life of the Quarry: Mineable reserves/Annual production= 10,69,550/10312.50 = 103 years. 1.8 Mining Methodology 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: There is no overburden on deposit. Boulders are exposed on top of the Black granite so North-west 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. 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. 8 Sri Sai Manasa Nature Tech Pvt. Ltd. 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.
