Almost all major metal and mining firms would be affected by the Supreme Court ruling canceling 214 coal blocks, but Naveen Jindal's JSPL and Aditya Birla Group's Hindalco would be among the worst hit, analysts said.
The Coal Ministry has issued show-cause to eight firms including Hindalco Industries and Mahanadi Coalfields, and sought explanation from five firms for delays in commencing production from mines allocated to them.
Though the current National Democratic Alliance government has not endorsed the figure, it has not even repudiated it.
