Proposed Limestone Slabs Quarry By M/s Khaja Stone Quarry Ogipur (V), Tandur (M), Vikarabad (D) Environment Management Plan 1. INTRODUCTION In a developmental activity like Limestone Slabs mining, all the exercises must co-exist satisfactorily with its surrounding condition so as to minimize the adverse impact on the environment. To control the likely adverse impacts and to achieve this goal, it is necessary to prepare an Environmental Management Plan, which has to be implemented by the proponents, in order to achieve environmental protection along with production profits. Hence, Environmental Management Plan has been prepared for submission to State Environmental Impact Assessment Authority / State Expert Appraisal committee as per EIA notification 2006 and the amendments thereof for clearance of the proposed mining area. M/s Khaja Stone Quarry has filed an application for quarry lease for Limestone Slabs over an extent of 0.404 Ha. in Sy. No: 58/8 of Ogipur Village, Tandur Mandal, Vikarabad District, Telangana and the Deputy Director of Mines and Geology, Hyderabad has granted the quarry lease in favor of M/s Khaja Stone Quarry for a period of 10 years vide notice No. 2007/QL/VKB/2018 dated 04.08.2018. Quarry Plan was approved by Deputy Director of Mines & Geology, Hyderabad region vide letter No: 3657/QP/VKBD/2018, Date 24.12.2018. 2. PROJECT PROPONENT Sri Khaja Moinoddin is a Quarry Contractor and mineral trader. He is doing the business of mineral trading for the past few years and is one of the key suppliers of Limestone Slabs to the industries from this region. Having significant experience in the mineral trading and Quarry of Limestone Slabs, to expand his business activities, applied Quarry Lease for limestone Slabs over an extent of 0.404 Ha. In Sy.

GEOLOGY 3.1 Topography: The entire Quarry lease applied area is a plain ground. The general ground level of the area is 439m reduced from the M.S.L. The applied area is a barren land and the rest sides being barren lands with working quarry of Limestone Slabs on east, north and south sides of the applied Q.L area. The lands to the west are open lands. There are approach roads from the applied area connecting to the roads going to Chatrasala from Tandur and Ogipur on western and northern side. 3.2 Regional Geology: The limestone deposits occurring in the area belong to man Bhima Basin group of Upper Proterozoic period. The rocks of Bhima basin rests over the rocks of Archean basement with a marked unconformity comprise of conglomerate and grit in the granitic terrain. They are considered equivalent of Vindhya systems. The following Stratigraphic sequence has been identified in the region: Geological Age Formations Recent Soil, Alluvium Bhima Group Upper Bhirnas(Flaggy Limestones) Middle Bhimas(Massive Limestones) Lower Bhimas (Shale & Sand stones) 3.3 Local Geology The limestone deposits occurring in Vikarabad district belong to a group of rocks known as Bhima series. The main Bhima basin is in the Bijapur and Gulbarga districts of Karnataka. Only a small eastern extension of the basin is exposed in Telangana in Vikarabad district. Within the quarry lease applied area the limestone occurs as grey to dark grey limestone and pink shale. Most of the area within the quarry lease applied is covered by black soil (ranges 1.0m to 1.25m) with outcrops of limestone here and there the geology of the area has been constructed based on surface geological mapping and sub-surface data of the adjacent working quarries .The general strike of the formation is NW-SE with beds usually dipping west and south west at low angles of 20 to 30, as observed from the outcrops exposed in the western side of the applied quarry lease area. The general geological succession in the area is given below: Litho unit Thickness Soil 1.0m to 1.25m Massive limestone 0-25.5m Pink Shale Not known 5 Proposed Limestone Slabs Quarry By M/s Khaja Stone Quarry Ogipur (V), Tandur (M), Vikarabad (D) Environment Management Plan In the subject applied Q.L area the massive thick bedded limestone occurs over a thickness up to 6.0m followed by the moderate to thin bedded limestone over a thickness of max. 7m and followed variegated limestone of reddish colour and followed by pink shale. 4. EXPLORATION/PROSPECTING: No trial pits have been made in the subject Q.L applied area. No boreholes of any type have been carried out in the subject area and have been proposed in the Quarry Plan. 5. RESERVES Reserves estimation is confined to the area and a thickness of ranging from 6.4 to 7.0m below the overburden in the form of black soil and thick bedded fractured limestone in the area and a recovery of 60% is considered for reserve estimation. The reserves of 21095 tonnes in these parts of Quarry lease are placed under 111 category. Summary of Geological & Mineable Reserves are given in table below: TABLE 5.1: Geological Reserves Category Quantity (M3) A. Total Geological Reserves 21095 B.

Excavations shall be carried out by simple excavators. Bench height will be maintained at 10m maximum with overall slope at 80° and maintaining of bench width does not arise in the subject area. Excavation and loading of the over burden waste shall be carried out with simple excavators of capacity 0.9 to 1.1 cu .m bucket capacity and 10 tonnes tippers .Cutting machines of manually operated of robotic shall be deployed for cutting of the slabs A five year working plan with sectional view showing the production and development blocks.
