Ten deaths were confirmed by police on August 10 but local media reports claimed on August 11 that the death toll had risen to 14, after reports of four more bodies being extricated from the rubble.
However, local authorities confirmed the recovery of a body on Friday and re-affirmed that the official death toll was at 11, according to The Indo-Asian News Service.
"The mutilated body of a woman was retrieved from the debris on Thursday. The death toll now stands at 11," police district superintendent Sanjeev Arora said.
Arora added that a man and a woman were still feared to be trapped under the debris and efforts were being made to locate them, according to IANS.
The accident occurred at a Mahanadi Coalfields open cast coal mine in Odisha when local villagers illegally collecting coal shells from the overburden were hit by a falling wall of waste.
Police believe heavy rain caused the collapse.
