AlHijjah 17, 1432, Nov 13, 2011, SPA -- 34 miners died, while nine were trapped, and feared dead, after a gas leak in an illegal mine in the south west of China, dpa cited Xinhua news agency as reporting Sunday. Rescuers said the chances of survival for the nine miners from the gas leak, which happened on Thursday, were slim. In a separate accident, seven miners were trapped underground after a coal shaft flooded early Sunday in north-west China's Gansu province, local officials said. The accidents came in the wake of the State Labour Protection Agency in Beijing ordering a tightening of safety standards at all mines in the country.
