Srinivasa Rao Pre-Feasibility Report 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 slate stone. It is used in making slates. 2.2 Brief Information about the Project The mining lease area of 1.0 Ha.is located in Non-forest, Government land. Open cast mining is followed and it has been proposed to produce approximately 11621.4 Cu.m./annum of Slate Stone. The nearest habitation is Kondramutla. Sri D. Srinivasa Rao has been granted a quarry lease for Slate Stone over an extent of1.0 Ha., in Sy.No.868/21 of Kondramutla village, Ipur Mandal, Guntur District, Andhra Pradesh by the Deputy Director of Mines & Geology, Guntur for a period of 10 years. 2.3 Need for the Project and Its Importance to the Country or Region Historically slate has been used for chalkboards, student writing slates, billiard tables, cemetery markers, whetstones, and table tops. Because it is a good electrical insulator, it was also used for early electric panels and switch boxes. Later is also used for interior flooring, exterior paving, dimension stone, and decorative aggregate. The demand for Slate Stone has increased due to rapid industrialization and growth in infrastructure. So the number of Slate Stone producing quarries is increasing in India. Due to bifurcation of State, there is a huge demand for Slate Stone. Hence they applied for Slate Stone Mine. As per EIA notification 2006 project proponent is submitting the proposal to get Environment Clearance for QL area of 1.0 Ha. from District Level Environmental Appraisal Committee/District level Impact Assessment Authority of A.P. constituted by MoEF, 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 and flooring. This project will help in reducing the Demand-Supply gap in the area. 2 Applicant: Sri D. Srinivasa Rao Pre-Feasibility Report 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 25 workers. It will provide employment to the people residing in vicinity. 3.0 PROJECT DESCRIPTION 3.1 Type of Project Including Interlinked and Interdependent Projects, If Any.

The rocks met with in the area are arranged in the order of superposition based on the description of W. Kings : Upper Cuddapah (Kadapah) System. 1) Krishna Series Srisailam quartzites Irlacon da quartzites 2) Nallamalai series Cumbum slates (shales and slates with quartzite intercalations) Bairenkonda quartzites (quartzites and sandstones with shale intercalations) The Nallmalai hill ranges constitute the central and western portions of the area and form a series of high parallel quartzite ridges trending from a N-S direction to ENE-WSW direction and rising to heights wall over 2000 to 3000 feet above sea level. Some of the highest points are, 2849 Kattulakonda, 2810 GundlaKonda, 2791 PeddaKonda, 2696 NaramamaluKonda, 2538 MattamKonda, 2457 SikharamKonda and 2395 Inaparati Konda. 7 Applicant: Sri D. Srinivasa Rao Pre-Feasibility Report 3.5.2 Local Geology Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay through low-grade regional metamorphism. lt is the finest grained foliated metamorphic rock. The proposed quarry lease area is raised 3.5 M above ground level below the ground level is 10.5 m the top soil is 3m within the quarry lease area village with tape relief in NW direction. The lowest contour is 118 M and highest contour is 121 M in topo plan In the proposed quarry lease area the slate occurs as flat exposure. Several out crops of slates observed separately by soil cover area. The rock is well developed foliation. The foliation is trending in N 700 W – S 700E. 3.5.3 Exploration Benches of each 6m height will be excavated with bench width of 3m. the presence of lime stone is up to 30m below ground level as proved reserves 3.5.4 Reserves The exposed slate stone deposit is found to be irregular in shape. The volume of the deposit is computed by cross sectional area method by multiplying the sectional influence. Geological traverses in the quarry and the study exposures in the vicinity of quarries facilitated to access the shape and size of the deposit in the area. It is a land surface deposit rising 6.5 M above ground level within the quarry lease area. (The lowest contour is 109 M and highest contour is 114 M). The surface of sheet rock is wavy and irregular. The Slate stone will be worked out to a maximum depth of 35 m only. TABLE 5.1: Geological Reserves S.
