A worker was trapped under the debris following a landslide at a coal mine in Chhattisgarh's Korba district on Thursday morning, the police said.
The incident took place at Kusmunda open-cast coal mine of South Eastern Coalfields Limited (SECL) when workers were pumping out rainwater from the mining area, said a police official.
Due to continuous rainfall, a portion of earth broke loose and crashed on the mine, he said.
Suresh Mahant (25), a contractual labourer, got trapped under the debris.
Rescue operation was still underway but the chances of his survival were slim, the official said.
