Two coal miners lost their lives after a coal mine collapsed in Balochistan's Harnai district on Thursday night. Seven others are still missing.

The bodies of two coal miners were retrieved from the debris, while Levis sources told DawnNews that a search operation was still underway for the seven missing miners.

Rescue workers and district administration officials are taking part in the operation.

Poor working conditions inside coal mines in Balochistan claim the lives of miners on almost daily basis in Harnai, Sowrange, Dukki, Mach and other parts of the province, but often go unreported.

Coal mining is considered much more hazardous than hard rock mining due to flat-lying rock strata, generally incompetent rock, leakage or explosion of poisonous gases and coal dust, collapsing of mine stopes or general mechanical errors from improper use and malfunctioning of mining equipment.

"There is no end to to the miseries of miners," Peer Muhammad Kakar, a labourer leader told DawnNews.
