"The nation as a whole has sufficient supply of coal," minister Piyush Goyal said late on Tuesday at a conference in Mumbai, according to a government statement released on Thursday. "Even if no coal is mined for the next 50 to 60 days, the power industry can rest assured that they would get an uninterrupted supply of coal to keep their plants running".

The turnaround of Coal India has been one of Prime Minister Modi's main successes, and the company is producing so much these days that it is having to consider exports for the first time as there is a local oversupply.
Coal Secretary Anil Swarup told Reuters this week that a team of Coal India officials will visit Bangladesh soon to finalise terms of a possible supply deal.
India's coal-fired power plants had an average of 21 days of stocks as of last Monday, and Coal India has millions of tonnes of already-mined coal it has been wanting to sell.
