Poor working conditions inside coal mines in Balochistan claim the lives of miners on an 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, it added.
