Srinivasa Rao Pre-Feasibility Report Endroye Village, Amaravathi Mandal, Guntur District, A. P. 2.0 INTRODUCTION OF THE PROJECT/BACKGROUND INFORMATION 2.1 Identification of Project and Project Proponent The proposed project area is found to have good deposits of Gravel. It is used in infrastructure development. 2.2 Brief Information about the Project The mining lease area of 1.76 Ac.is located in Non-forest, Government land. Open cast mining is followed and it has been proposed to produce approximately 8,204 Cu. m./annum of Gravel. The nearest habitation is Lemalle Village located at a distance of 1.0Km due South of Quarry Lease. 2.3 Need for the Project and Its Importance to the Country or Region The demand for Gravel has increased due to rapid industrialization and growth in infrastructure. So the number of Gravel producing quarries is increasing in India. Due to bifurcation of State, there is a huge demand for Gravel. As per EIA notification 2006 project proponent is submitting the proposal to get Environment Clearance for QL area of 1.76 Ac.from District Level Environmental Appraisal Committee/District level Impact Assessment Authority of Guntur constituted by MOEF, GOI for the purpose of operating the quarry lease for which Notification is issued. 2.4 Demands-Supply Gap There is huge demand since the material is used extensively in building construction infrastructure development. 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 the25 workers. It will provide employment to the people residing in vicinity. 2 Sri M. Srinivasa Rao Pre-Feasibility Report Endroye Village, Amaravathi Mandal, Guntur District, A.

P. 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 1.76 Ac.,andthe production rate is 8,204 Cu. m./annum of Gravel.The lessee follows open cast semi mechanized mining. Production parameters The Mineral production target for five years is given in Table 3.1.

The Archaean basement comprising the granite-gneisses, Schists, Khondalites, Charnockites and basic dykes of dolerites form the predominant rock types in the central part. The fringe of the Archaeans in the central part is represented by Cuddapah basin, namely Nallamalai group of Upper Cuddapahs. In a sequential order, the younger Kurnools occurring in the Cuddapahs and those in the western parts of the district are thrust over by the Cuddapahs and these in turn by the Archaean granite-gneisses. The Upper Gondwana group of sandstone and shales out crop are seen at places between Guntur and Tenali. The youngest rock types of the district appear to be of Mio- Pliocene age followed by the Alluvial deposits of Recent to Sub-Recent age. 7 Sri M. Srinivasa Rao Pre-Feasibility Report Endroye Village, Amaravathi Mandal, Guntur District, A. P. 3.5.2 Local Geology Geologically the area may formed due to prolonged weathering of Khondalites. These rocks finally gives rise to Gravel. The Gravel is visually thick in red color and it is useful for filling / Earth works purpose only. The Eastern Ghats Super group comprising Khondalite and Charnockite Groups is exposed in the central part of the upland area. The Khondalite Group of rocks are seen as prominent hill ranges (strike ridges) south of Vijayawada, extending towards north and northeast. They consist of quartz, k-feldspar, clay, garnet sillimanite, graphite, with or without corundum. In the northeastern part, a number of calc granulite and quartzite bands are present, within khondalite. The rock Khondalite available in the applied area is moderate dense rock exposed as out crop. Mineral Gravel occurs as a bed at the foot of the hill, the thickness of the bed becomes thin towards the upper portion of the hill. The occurrence of the Gravel seems to be derived from the weathering of the insitu formations, due to the stream action and local drainage the deposition of the gravel is high at the foot of the hill. Below gravel road metal is available. The rock is medium to coarse grained texture composed of greasy quartz, hypersthene, orthoclase and plagioclase with or without garnet. The rock is massive, with widely spaced vertical to sub vertical joints trending in NE-SW direction. It is observed that sheet joints are absent. 3.5.3 Exploration Benches of each 7,6.5,6, and 5.5m height will be excavated. The presence of Gravel is proved surrounding gravel quarries up to 6 m depth below ground level as proved resources. Core bore hole drilling is not required. 3.5.4 Reserves Two cross section (A-A’ B-B’) is drawn perpendicular to the slope direction for profile purpose. The reserves are estimated in cross sectional method of estimation as given below. 8 Sri M. Srinivasa Rao Pre-Feasibility Report Endroye Village, Amaravathi Mandal, Guntur District, A. P.

Hence, it is proposed to mine the Gravel by open cast, using semi-mechanized method by developing the benches of 7,6.5,6,5.5 respectively M height 1.5M bench width with shallow drilling and blasting. The development of benches will be maintained @ 40 - 60° safety slopes. Drilling Not applicable It is proposed to produce 32417 Cum. of Gravel during Five years plan period with an average annual production of 6483.4 Cu. m. from an area of 5188M2 Benchs of 7M in 1st year and 6.5M in IInd and IIIrd 6 M in IVthyear and 5.5 inVthyear height will be developed during the plan period. The applicant proposes to take up quarrying operations in entire quarry lease applied area. The excavation activity will be started in Eastern part of the quarry lease applied area and then continue to move towards Western side.
