Approval of CCL Board Annexure – I Project Report for Govindpur Ph-II OCP, CCL CMPDI CHAPTER- I 1.0 INTRODUCTION: Govindpur Phase-II OCP is located in Bokaro District of Jharkhand. It is situated in the north western part of the East Bokaro Coalfield and it is a part of the Kathara Area of Central Coalfields Limited. It lies adjoining to Sawang OCP in the west. This Project Report envisages producing 1.2 MTY of ROM power grade coal (Grade E) from “Geological Report on Coal Exploration Govindpur North Block, East Bokaro Coalfield” prepared in Dec 2001 and the area south of Bermo Seam incrop upto 200m depth line on Seam-VI floor in the south. It is also envisaged to remove both coal and OB departmentally. 1.1 Draft PR of Govindpur Ph-II OCP (0.80 MTY) Govindpur Opencast is a new mine and a Draft Project Report was prepared in Feb 2008 to produce 0.8 MTY of coal from the Govindpur North sub-block of Govindpur Block in East Bokaro Coalfield. Further reserves from an area to the south of the incrop of Bermo seam has been added to the reserve of Govindpur North Block and the capacity of the PR enhanced to 1.2 MTY. 1.2 Justification for locating the project in the forest area : Karo group of seams is proposed to be exploited in Govindpur Ph II OCP. It is a huge source of non-coking coal. This reserve of 19.53 MT non-coking coal lies below the patches of forest and non-forest land. Hence, unless the forest land above the coal seams is released, the coal seams cannot be exploited. Mining being site specific it is not possible to divert the operations to non- forest land. Job No. 340721 Chapter-I-1 Project Report for Govindpur Ph-II OCP, CCL CMPDI 1.3 SCOPE OF THIS PROPOSAL In this proposal of Govindpur Ph-II OCP (1.2 MTY): a) The reserve from an area to the south of the incrop of Bermo seam was added to the reserve of Govindpur North Block and the capacity of the PR was increased to 1.2 MTY. b) The option proposed in the present PR for Govindpur Ph-II OCP (1.2 MTY). They are detailed as under: OPTION-I Coal Production Departmental OB removal Departmental Average Grade E CHP Coal size (-) 100mm Evacuation of Pipradih Railway coal Siding c) The proposal envisages for shovel dumper combination of mining. d) Departmental Coal Handling Plant is proposed. Product size of (-) 100 mm has been proposed. Job No. 340721 Chapter-I-2 Project Report for Govindpur Ph-II OCP, CCL CMPDI CHAPTER – II 2.0 LOCATION, COMMUNICATION, TOPOGRAPHY & CLIMATE 2.1 Location The Govindpur North Block covering an area of 1.75 sq km lies between latitudes 23 o48'30" & 23 o49'30" N and longitudes 85 o51'15" & 85 o52'45" E. It is included in the Survey of India Toposheet No. 73E/13. The block lies to the east of Sawang Colliery. 2.2 Communication Govindpur Ph-II OCP is well connected by rail and road. The Gomoh- Barkakana loop line of Eastern-Central Railway is about 2km from the project. Bokaro Thermal Power Railway Station is the nearest railway station. The OCP is about 80km from Hazaribagh. It is about 130km from Ranchi via Ramgarh - Tenughat Dam road. The Sawang colliery was connected to this Project by a seasonal causeway over Konar River, which has been washed away. It is being proposed to construct a bridge over Konar River at the same place. 2.3 Topography The surface topography of the block is shown in Drg. No. RI-3/G/5707. The block is usually slightly rolling with gentle southerly slope. The maximum elevation is 318m above MSL and minimum 231 & 240m along the flanks of Konar River & Montico Nala respectively. The Project lies in the catchment area of Konar River & Montico Nala. The Konar river flows in the south easterly direction and the Montico nala flows in the south direction and joins the Konar River to the south of the block. 2.4 Climate The area experiences semi to extreme climate with day temperature as high as 45 0C during the summer, which falls down to around 5 0C in night during winter. The rainy season lasts from mid June to mid September. Job No. 340721 Chapter-II -1 Project Report for Govindpur Ph-II OCP, CCL CMPDI Chapter-III Geology of the Block 3.1.1 General: The Gobindpur North OC Block with an area of 1.55 sq km is located in the NW part of East Bokaro Coalfield, and is under the administrative control of Kathara Area of CCL. The OC block is part of the area covered in Geological Report on Gobindpur Block prepared by CMPDI in 1993 wherein it has been designated as ‘Gobindpur North Sub Block’. This is the northern most part of Gobindpur Block where all the Karo group of seams are available. The Upper Karo group of seams are thick with open cast potentiality while the lower Karo group seams have underground potentiality only. The details given in this report are based on the ‘Geological Report on Coal Exploration, Govindpur North Block (Karo Group of Seams)’ prepared by CMPDI in December, 2001. 3.1.2 Location: The Gobindpur North OC Block covering an area of 1.55 sq km lies between the latitudes 23 deg 48’ 30” to 23 deg 49’ 30”and longitudes 85 deg 51’ 15” to 85 deg 52’ 45” and is included in the Survey of India Toposheet no 73E/13. The block lies to the immediate east of Sawang Colliery and some distance to the north of Bokaro TPS of DVC. 3.1.3 Limits of Gobindpur North Block : North: E-W trending Karharbari/Metamorphic contact South: 200m depth line on floor of Seam-VI (south of Incrop of Bermo Seam) East: Surface trace of fault F16 (near Govindpur –Pichri fault) West: Fault F7 (near Borrea Fault) Job No. 340721 Chapter-III -1 Project Report for Govindpur Ph-II OCP, CCL CMPDI 3.1.4 Communication : The Gobindpur North OC Block is very well connected by rail and road. The Gomoh-Barkakana loop line of EastCentral Railway passes about 2 km south of the southern boundary of the block where Bokaro thermal Power railway station is the nearest railway station. The Hazaribagh-Bermo metalled road passes close to the northern and eastern sides of the block. The block is about 80km from Hazaribagh and 2km from Kathara GM office. 3.1.5 Topography and Drainage : The northern region is extremely hilly on account of outcrops of basal Barakar Formation, which are hard, compact and resistant to weathering. The southern region is slightly rolling with gentle southerly slope. The maximum elevation in the hill region is 331 m above MSL and minimum is 231m and 240m along the flanks of Konar River and Montico Nala respectively. The entire Gobindpur North Block lies in the catchment area of the Konar River, which is a perennial and major tributary of Damodar River. 3.1.6 Climate: The block lies in tropical monsoon region with day temperature during summer rising to as high as 45 0 C and fall down to around 5 0 C in winter. The rainy season lasts from middle June to Mid September. 3.1.7 Previous Work : The IBM (1959), NCDC (1965), CCL and CMPDI (1993 and 2001) explored the area through drilling. The present PR is based on the latest GR of CMPDI on Gobindpur North Block (December, 2001). 3.2.1 Drilling: Drilling in the block was taken up by various agencies at various periods of time : Job No. 340721 Chapter-III -2 Project Report for Govindpur Ph-II OCP, CCL CMPDI Table 3.1 Agency Phase BH Code No of BH drilled Meterage Drilled (A)Within the Block (i) NCDC NCBG 7 659.27m. (ii) CMPDI CMEG 28 1988.25m Total 34 2647.52m The borehole density comes out to be 22 boreholes per sq km.
