Sambalpur, September 8 (LocalWire) Coal India subsidiary Mahanadi Coalfields Ltd has removed overburden to the tune of 63.5 million cubic meters by September 2 this fiscal year as it prepares to ramp up coal output when the demand grows, a senior company official said on Tuesday.
Overburden removal is a process of removing the soil and rock from the earth surface so that coal can be extracted from the open caste mines.
Since the demand for power and coal dropped during the coronavirus related lockdowns, the public sector company focussed on overburden removal so that it can accelerate coal production and provide coal to its customers in short notices when the demands pickup.
Senior company officer Deccan Mehra told LocalWire the overburden removed from its mines stands 56 per cent more than what it removed last year by September 2.
The company had removed 40 million cubic meter overburden by September 2 last year.
