New Delhi: Coal and Power Minister Piyush Goyal will inaugurate by month-end two mines of Western Coalfields Ltd, an arm of Coal India which is working towards meeting 1 billion tonnes production over the next 5 years. “Towards the end of October, probably around 25th, I am going to open two more mines,” Goyal said. In the last seven months, WCL has opened eight mines, he said, adding, “ever heard in the history of India that the government company is opening 10 mines in 10 months”. In 24 months, starting from March, WCL would have opened 24 mines, he added.
