Rajhara opencast mine is located in Daltonganj Coalfield, in Palamu district. It is 4 km from Kajri railway station on the Barkakana-Son Nagar line. Coal will be mined from 3 coal seams: Rajhara Top Seam with extractable reserve of 1.721 million tonnes, Rajhara Middle Seam with extractable reserve of 0.749 million tonnes and Rajhara Bottom Seam with extractable reserve of 13.139 million tonnes. The mine has a capacity of 0.75 million tonnes per year.[1]
Rajhara mine was started in 1842 by Bengal Coal Company, making it one of the oldest mines in the country. The ownership of mine was transferred to Ram Sharan Das and Brothers in 1969 and subsequently, the mine was nationalised in 1973. It was initially worked by underground method but after nationalisation it was converted to an opencast mine to recover good quality reserves of coal. The mine is situated close to Sadabah River, a tributary of North Koel River. The mine was closed in October 2010 to avoid possibility of being flooded. Additionally, there were issues related to environmental clearance. With several corrective and precautionary measures for the safety of the mine, its environmental clearance was issued on 14 February 2019. The mine was reopened in the presence of V.D.Ram, Member of Parliament and Gopal Singh, CMD, Central Coalfields Limited, on 25 February 2019.
Tetariakhar expansion open cast project (0.5 to 2.0 million tonnes per year normative and 2.5 mty peak) is located in the North Karanpura Coalfield in Latehar district.[2]
