MINE CLOSURE REPORT FOR DHORI KHAS UNDER GROUND PROJECT (0.17 MTY) (CENTRAL COALFIELDS LIMITED) AUGUST 2012 Regional Institute – III Central Mine Planning & Design Institute Ltd. (A Subsidiary of Coal India Ltd.) Gondwana Place, Kanke Road Ranchi-834008, Jharkhand 1 INTRODUCTION 1.1 About the Mine Dhori Khas is an existing underground mine. Since its inception, the maximum production was 0.106 MTPA in the year 1993-94. At present, the Karo Spl. seam-III is being worked by manual development and depillaring with caving (Bord &Pillar). Due to low reserve and erratic nature of roof of Karharbari formation, mechanization is not possible. The life of the mine is 15 years. Details of Mine Dhori Khas is an existing Underground Project with 0.166 MTPA normative capacity & 0.190 MTPA peak capacity .Total balance mineable reserve is 3.35 MT. Grade of coal is W-II and life of project is 15 years. At present, it is working in Karo seam-III by manual development and depillaring with caving (Bord &Pillar). Its balance reserve is 3.35 MT and balance life is 15 years. Coal produced from this is transferred to Swang Washery , Kathara Area. Produced coal will be supplied to basket linked consumers.

Nearest Railway station is Phusro at a distance of 3.00 km on Gomo- Barkakana loop line. It is about 130 km from Ranchi via Jaina more on NH- 23. The nearest air port is Ranchi at a distance of 130 km by road. 1.1.7 Topography of the area The topography of the area is rugged and pronounced with hills and valleys. The surface RL varies from 213m to 323m. The main drainage of the area is Damodar River flowing from west to east in the south of the mine. Three nalas namely BarkiJoria, Ghorgara and Tisri are small nalas flowing from north to south passing through the property discharge their load to Damodar River. Other drainage lines also discharge their loads to either these nala or Damodar River. 1.2 Reasons for Closure To restore the disturbed area after extraction of planned quantity of coal, to the acceptable limit of local community and regulatory authority. 1.3 Need of mine closure planning 3 1.3.1 Mining activities leave long lasting impacts on the landscape, ecology and on local inhabitants. These activities disturb the delicate environmental and social equilibrium that exists in its area of influence. Hence, it becomes imperative on part of the mine operator to restore the equilibrium in the mine affected area that existed in the pre-mining period. Thus, any mining venture must have adequate closure plan, aimed at rehabilitation of disturbed area, which should be acceptable to local community as well as regulatory authority. 1.3.2 Mine closure encompasses rehabilitation process designed to restore physical, chemical and biological quality disturbed by the mining activities. Mine closure is not just something that happens at the end of a mine’s life rather mine closure is an ongoing series of decisions and activities beginning in the pre-mining stage of mine and ending with a sustainable site that can be returned to the community. 1.3.3 Thus, a Mine closure plan needs to define the liabilities, responsibilities and authorities of the different agencies like the mine management, other regulatory bodies, Central and State Governments after mine closure. Various objectives of the advance mine closure planning are as follows: a. To allow productive and sustainable after-use of the site, which is acceptable to the mine owner and the regulatory authority b. To protect public health and safety c. To eliminate environmental damage and thereby encourage environmental sustainability d. To minimize adverse socio-economic impacts of mining activities e. To protect the flora and fauna of the area affected by the mining f. Effective use of the assets created in course of mining 1.3.4 Primarily, the mine closure activities are planned in two stages. The initial plan identifies the activities required to be executed as the mining activities progress after the inception of the Project. These activities may undergo subtle changes depending upon the actual site condition during implementation. Finally, a detailed closure plan is to be prepared 4-5 years before the actual closure time of the mine depending upon the existing parameters at that point of time. Plans Enclosed The following surface plans have been enclosed along with this mine closure report plan: a. Pre mining Land use plan of core zone b. Quarry & Dump Plan at the end of mining. c. Post mining land use plan with reclamation. 4 2.0 Financial Provisions Mine Closure activities of Dhori Khas UGP would be a constant exercise for the mine which would begin with the commencement of mining operations and continue till post closure. The mine closure activities would naturally entail certain expenditures, which will have to be borne by the mine operator. 2.1 Revenue expenditures This would cover the activities which are being executed along with normal mining operation and would continue to be executed in course of execution of the Project. The cost of progressive mine closure activities is already part of the project cost. 2.2 Expenditures to be incurred just prior to actual mine closure and in the post closure period 2.2.1 As per MOC guidelines, a corpus escrow account @ Rs. 1.0 lakhs per Ha of the property leasehold shall be opened with the coal controller organization to meet the expenses of final mine closure. Thus the total expenditure on his front may be calculated in following manner: The cost expenditure after closure of mine will be met from the corpus escrow account deposited by the mine operator. However, the additional amount beyond the escrow account will be provided by the mine operator after estimating the final mine closure cost five years prior to mine closure (as per the mine closure guideline). The progressive mine closure will deal the land reclamation as per the calendar plan of project report. The cost of progressive land reclamation is already part of the project cost. Therefore, the escrow account for mine closure will deal only the final mine closure. The detail of escrow account The total mine lease area is 456.75 Ha, so the corpus based on August, 2009 rate is Rs. 456.75 Lakh @ Rs. 1.0 Lakh/Ha of lease area. The wholesale price index in August, 2009 and April, 2012 is 129.60 and 163.50 respectively. So the current value of corpus is Rs 456.75x163.50/129.60 Lakh, which comes to Rs. 576.22 lakh. The provision for mine closure expenditure made in the accounts of 2010-11 and 2011-12 for Dhori Khas UGP is 22.65 Lakh. So the net corpus has become Rs. (576.22 - 22.65) = Rs. 553.57. Since this is an operating/existing mine, this corpus is to be divided by balance life of mine. The balance life of the mine is 15 years. So, by dividing by 15 years, the annual corpus comes to Rs. 36.90 Lakh. This amount is to be deposited in escrow account every year with 5% escalation. 5 ESCROW ACCOUNT Dhori Khas UGP 1) Current value of Corpus (Total project 576.22 areax1x163.5/129.6, fig. in Rs.
