With the power sector, a major consumer of the dry fuel, witnessing a drop in fuel consumption amid the lockdown, CIL has shifted its focus to overburden removal -- the process of removing the top soil and rock to expose coal seams in its open cast mines.
The enhancement in overburden removal will enable CIL to accelerate production whenever the demand picks up and coal can be supplied to its customers at short notice.
Over 95 per cent of CIL's production comes from its 171 open cast mines.
The PSU removed 114.43 million cubic metres of overburden in its open cast mines in April 2020, as compared to 104.22 million cubic metres a year ago, registering an increase of 9.7 per cent.
