2.2 Brief Information about the Project The mining lease area of 3.000Ha. is located in Government land. Open cast semi mechanized mining is followed and it has been proposed to produce approximately 10260 Cu.m / annum of building stone material. The nearest habitation is Nellibanda village, which is at a distance of 1.5 km.
2.3 Need for the Project and Its Importance to the Country or Region The demand for building stone has increased due to rapid industrialization and growth in infrastructure. So the number of building stone producing quarries is increasing in India. Building Stone and M-Sand have to produce as they form the aggregate in the concrete mixture used in the construction industry. The Indian Railways also requires the material for the maintaining the existing network and also for the never ending expansion.
As per EIA notification 2006 project proponent is submitting the proposal to get Clearance for production capacity of 10260 Cu.m / annum from District Level Environmental Appraisal Committee/District level Impact Assessment Authority of Andhra Pradesh constituted by MoEF&CC, GOI for the purpose of grant of quarry lease for which Notification is issued.
2.4 Demands-Supply Gap There is huge demand since the material is used extensively in Construction, Railways, Roadways and many other sectors. This project will help in reducing the Demand- Supply gap in the area.
2.5 Domestic/ Export Markets The material is used in the domestic market and in there is no scope for exporting the material.
2.6 Employment Generation Proposed mining is semi mechanized method and this project operation will provide livelihood to the 34 workers. It will provide employment to the people residing in vicinity.

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 mine has lease over an area of and the 3.000Ha. production rate is 10260 Cu.m / annum. The lease follows open cast semi mechanized mining.
3.5 Geology and Reserves
3.5.1 Topography Topographically the Q.L. area is a hillock gently slopes towards West direction. Generally it is low lying plain land with an average altitude of 426m to 453m above M.S.L. and dendritic to sub dendritic drainage is observed.
3.5.2 Geology The Geological formations in the Kurnool District 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 Gondwana block. The remaining parts of District are 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 is 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

3.6 PROJECT DESCRIPTION WITH PROCESS DETAILS
3.6.1 Method of Mining The quarrying in the sanctioned area is of open cast method other than fully mechanized mining method with drilling and blasting. The ROM will be sized and sorted in the crusher established outside the quarry lease area loaded on to tippers and tractors using JCB, Mining will be carried out by formation of benches of height 6 m each. Considering the technical parameters like surface topography, quality variations, geo-technical aspects are required for production and extraction of building material in the area. It is proposed to work from the deposit by adopting benches formations with ultimate pit

slope of 45°. The benches height and the width will be maintained as specified by D.G.M.S. The width of the working benches shall not be less than the height. The year wise production and development plan indicates the site for disposal of waste, site for afforestation as shown in map. The plan showing position of the working pit proposed for extension etc. Due care has to be taken in designing the benches and advancing the benches for production. The ground water table is much below the proposed working level.

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 material and dumping in stock yard. Loading of the building stone material will be done mechanically by tippers and transported from the quarry to the required site. The rejected material will be dumped separately.
3.7.1 Use of Mineral The extracted material will be used in Construction, Railways, Road ways and many other sectors
3.7.2 Processing No processing at site is involved.
3.8 Resource Optimization/ Recycling and Reuse Not envisaged.
3.9 Availability of Water Its Source, Energy/ Power Requirement and Source
3.9.1 Water Requirement Water is required only for drinking purposes and dust suppression. The number of working people is around 34 so the total water requirement will be around 5.0 KLD. This water will be supplied from bore wells of nearby area.
3.10 Quantity of Wastes to be Generated (Liquid and Solid) And Scheme for their Management/ Disposal
3.10.1 Solid Waste Generation& its Disposal There is no mineral reject or sub-grade mineral in this quarry. However, about 5% interstitial voids and intercalated waste is anticipated which is computed separately. This will be utilized for the formation of internal roads and balance utilized to form a barrier all along the 7.5m buffer zone of the QL applied area to a height of 27m.
3.10.2 Liquid Effluent No liquid effluent will be generated at the mine site. The domestic wastewater generated will be sent to septic tanks followed by soak pits.

PROJECT: Road Metal PRE-FEASIBILITY REPORT APPLICANT: Sri. A.Rama Swamy
4.1.1 Nearest Railway Station Aspari railway station is about 30 km distance towards SW from the mine area.
4.1.2 Nearest Airport Rajiv Gandhi International Airport is about 197 km distance from mine site.
4.2 LANDFORM, LANDUSE AND LAND OWNERSHIP The notified area is Government land. It is barren with boulders and followed sheet rock is exposed in the area and also sheet rock is seen in the surface level with soil cover..
4.3 Climatic data from secondary sources The average annual rainfall is about 529.6 mm. The observed maximum temperature is 380Cin summer season and minimum temperature is 180C in winter seasons. The rainfall does not disturb the mining activities. Moderate wind velocities, prevailed in north east to south west direction.
5.0 PLANNING BRIEF 5.1 Planning Concept The quarrying in the sanctioned area is of open cast method other than fully mechanized mining method with drilling and blasting. The ROM will be sized and sorted in the crusher established outside the quarry lease area loaded on to tippers and tractors using JCB, Mining will be carried out by formation of benches of height 6 m each. Considering the technical parameters like surface topography, quality variations, geo-technical aspects are required for production and extraction of building material in the area. It is proposed to work from the deposit by adopting benches formations with ultimate pit slope of 45°. The benches height and the width will be maintained as specified by D.G.M.S. The width of the working benches shall not be less than the height. The year wise production and development plan indicates the site for disposal of waste, site for afforestation as shown in map. The plan showing position of the working pit proposed for extension etc. Due care has to be taken in designing the benches and advancing the benches for production. The ground water table is much below the proposed working level.
5.2 Population projection The project will employ mostly workers from nearby villages. There will not be any increase in population due to the project.
5.3 Land use planning The project site is Government land. There will be change in landuse as the material is excavated.
