The world's biggest coal company just shut down 37 mines because they are not economically viable anymore

The largest coal mining company in the world has announced it will close 37 mines because they are no longer economically viable. Coal India, which produces around 82 per cent of India's coal, said the mines would be decommissioned by March 2018. The closures, of around 9 per cent of the state-run firm's sites, will reportedly save around 8,000,000,000 rupees (£98m).
