There is still more bad news for coal mining companies, with the mines ministry recommending that coal miners mandatory share 100 per cent royalty with project-affected families. The recommendation, if implemented, could severely dent coal miners’ bottom line.

It would not only increase the annual outgo of monopoly producer Coal India Ltd (CIL) on account of benefit sharing, but also bring captive block holders, including large companies like Tata, Reliance, Essar, GMR, GVK and Aditya Birla Group, under the benefit-sharing net.
