Coal India Ltd (CIL), which meets about 80% of the country's coal requirements, faces serious difficulties in stepping up its coal production even as the domestic demand for coal grows at a fast pace, thanks to capacity addition in key sectors like power, cement and steel. Growing environmental hurdles to mining operations in India have forced the world's largest coal miner to look at acquisition of overseas coal assets to meet domestic demand and keep growing. In an interview CIL chairman NC Jha discusses his company's business plans and also replies to the criticism that the PSU has not done enough to increase its production to meet demand.
