MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (3.50 Mty) 1.0 INTRODUCTION 1.1 BACKGROUND OF PROJECT REPORT The Amalgamated Gondegaon-Ghatrohan OC project had been envisaged in Gondegaon-Ghatrohan block in Kamptee Coalfield. The project consists of two sub quarries i.e. Gondegaon sub quarry & Ghatrohan sub quarry. Presently, both the sub-quarries are in operation by departmental HEMM (in Gondegaon sub-quarry) as well as Out-sourced HEMM (in Ghatrohan sub- quarry). PR for Gondegaon OC was prepared in November, 1989 for a capital investment of Rs.6796.25 lakhs and target production of 0.75 Mty and was approved in the year 1992 in Departmental Option. Excavation work of Gondegaon OC was started in 1994-95 and coal extraction commenced in 1995-96. Due to increase in the expenses by 40.67%, a Revised Cost Estimate was prepared for 0.75 Mty in June, 1998 for a total capital investment of Rs.9560.24 lakhs (existing capital of Rs.6151.95 lakhs + balance expenditure of Rs.3408.29 lakhs). The RCE was approved by CIL Board on 25.8.1998 for a capital investment of Rs.9560.24 lakhs. A Completion Report for Gondegaon OC mine was prepared by WCL in 1999 for a total capital expenditure of Rs.9535.31 lakhs. Subsequently, PR for Gondegaon Extension OC including Ghatrohan OC was prepared in June, 2004 for a capital investment of Rs.12415.67 lakhs (Gross Block) for a capacity of 1.50 Mty. However, it was sanctioned for incremental capacity of 0.75 Mty with an incremental capital of Rs.2753.71 lakhs. Thereafter RPR for Amalgamated Gondegaon-Ghatrohan OC (December- 2010) was prepared to enhance the production capacity from 1.50 Mty to 2.00 Page - 1 MINING PLAN MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) Mty. The balance coal reserves and volume of OB calculated as on 01.4.2010 were 29.07 Mt and 153.91 Mm3 respectively at a stripping ratio of 5.29 m3/t. This RPR was accorded 2nd Stage approval by WCL Board on 07/01/2011 with an additional capital investment of Rs 73.8846 crores in Partial Hiring option. As desired by WCL, updation of the approved RPR (Dec. 2010) was done at August 2015 prices and discussed in the TSC meeting at WCL HQ on 11/09/2015 wherein it was directed to review report for a higher capacity on the basis of joint technical meeting between CMPDI, WCL HQ, WCL Nagpur Area & mine officials. Subsequently, a meeting was held on 12/9/2015 at CMPDI, Nagpur and it was decided to prepare Revised Project Report of Amalgamated Gondegaon - Ghatrohan OC for a target capacity of 2.50 Mty. Based on the decisions taken in various meetings with WCL (HQ), Nagpur Area and mine officials, Revised Project Report of Amalgamated Gondegaon Ghatrohan OC for 2.50 Mty capacity was prepared in November, 2015 considering the latest scenario of land acquisition and further project requirements communicated by Mine/Area. The Revised Project Report of Amalgamated Gondegaon Ghatrohan OC (2.50 Mty) was approved by WCL Board in its 273rd meeting held on 3rd February, 2016. GM (P&P), WCL vide his letter no. WCL/GM (P&P) / MR / 18/484 dated 09.02.2018 requested CMPDI, RI-IV, Nagpur to update the RPR of Amalgamated Gondegaon Ghatrohan OC for 3.50 Mty capacity. Based on the decisions taken in various meetings with WCL (HQ), Nagpur Area and mine officials, following changes were incorporated in the RPR of Amalgamated Gondegaon Ghatrohan OC updated in the month of February- 2018 : a) Target capacity of the mine was increased from 2.50 Mty to 3.50 Mty and accordingly life of mine reduced to 7 years as on 01.04.2018. Page - 2 MINING PLAN MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) b) Additional Provision was made for 1 no. of Mobile Crusher on hiring and Electronic Weighbridge to cater the increased capacity of the mine. c) Provision of Manpower was increased to 921 considering an increase of 201 manpower over & above the present day manpower of 720 . d) Provisions for P&M revised considering correspondence with WCL. e) Provisions for HEMM was revised considering existing HEMM at Gondegaon Ghatrohan OC. After incorporating the above, the RPR of Gondegaon Ghatrohan OC mine was updated for the month of February-2018. The above RPR was discussed in the meeting of Technical Sub-Committee of WCL Board held on 07.03.2018 at WCL (HQ), Nagpur. In the meeting, it was discussed that there is wide difference in the quality of upper set of coal seams (Seam-V and IV) and lower set of coal seams (Seam-III & II) in Amalgamated Gondegaon Ghatrohan OC mine. Finally, it was decided that separate coal stocks and dispatch arrangement for inferior quality coal of upper seams (V and IV) and better quality coal of lower seams (Seam-III & II) will be maintained in the mine and accordingly, sale price of both type of coal will be considered separately as per their corresponding year-wise quantity in economic evaluation. Based on the above decision, RPR of Amalgamated Gondegaon Ghatrohan OC mine was prepared in the month of March, 2018.

Lateron, the Ministry of Environment, Forest and Climate Change vide letter no. J-11015/106/2009-IA.II(M) dated 28.03.2019 accorded approval for continuance of Gondegaon Extension Opencast Mining Project from 2.50 MTPA to 3.50 MTPA in area of 917 ha (mine leasehold area 845.74 ha) for a further period of one year. The RPR for Amalgamated Inder-Kamptee Deep OC was approved by WCL Board in September,2018 in which 54.34 ha land was proposed to be transferred from neighbouring Gondegaon-Ghatrohan OC. Accordingly, EC application for amendment in EC of Expansion of Kamptee Deep OC ‘for a capacity of 3.20 MTPA within a mine lease area of 857.60 ha was discussed in EAC in its 46th meeting held on 25.06.2019. The EAC, after deliberation observed that the proposed amalgamation involves carving out some area of Page - 4 MINING PLAN MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) adjoining Gondegaon Opencast coal mining project and thus requiring amendment in its environmental clearance also. There being no proposal in this regard, the committee was not inclined to take the proposal forward. Hence, for applying for amendment in the existing EC of Expansion of Gondegaon Extension OC, a Mining Plan with mine lease area of 791.40 ha (845.74-54.34) for a capacity of 3.50 MTPA has been prepared. 1.2 EXISTING STATUS Five coal seams which are characteristic of Kamptee Coalfield, are present in the Gondegaon-Ghatrohan block also. All these seams occur in the Middle Barakar horizon of about 100 m thickness. The seams in Kamptee Coalfield are numbered from bottom to top, the bottom-most Seam-I is the oldest, while the top most Seam-V is the youngest. The oldest Seam-I is found to be deposited around 100 m above the Talchir-Barakar contact. Of the five seams, Seams-II, III & IV occur in 2 to 3 split sections, while Seam-V is present as a single horizon. Seam-I is impersistent and also thin, mostly below 0.90 m thickness, hence not considered in this report. Due to the steep gradient & multi-seam characteristics, shovel-dumper system of mining is in vogue. Seam - II to V occur in Gondegaon-Ghatrohan Block in nine sections, viz. Seam-I (Bottom), I (Top), II (Bottom), II (Top), III (Bottom), III (Top), IV (Bottom) {Seam-IV Bottom and IV Middle may be considered as Seam-IV Bottom due to very thin parting between them}, IV (Top) & V. The various performance parameters of the mine from 2012-13 to 2016-17 as per cost sheet are as follows:- Sl.
