About:

=> Deucha-Pachami-Dewanganj-Harinsinga coal block is the second-largest coal block in the world.

=> India's largest coal mine is located in the southwestern part of Birbhum Coalfield in West Bengal.

=> The block has a thick coal seam trapped between equally thick layers of rocks, mostly basalt. It has great economic value.

=> The existence of these thick basalt layers, however, makes mining of coal difficult; foreign investment and technology will be hence needed for mining.

=> An estimated 1,198 million tonnes of coal and 1,400 million tonnes of basalt are in the block.
