Country's coal stocks have touched an all time high of 70 million tonnes and the Coal India Limited (CIL) has sought additional rakes from railways to liquidate at least 25 million tonnes from its inventory. According to Coal India Chairman N C Jha accumulating stock of coal has been a serious concern for the country's largest producer CIL. He said the stock has been accumulating over a decade on account of inadequate transportation facilities, mainly due to shortage of railway rakes. Last month, Coal Minister Sriprakash Jaiswal had assured the Group of Ministers on Coal to reduce stockpile from 70 million tonnes to 42 million tonnes by March 2012.
