Eight coal miners were killed, two injured and other four missing after flood water rushed into a coal mine in southwest China's Guizhou Province, sources with the provincial administration for work safety supervision said Wednesday. Twenty miners were working underground at the Longhua colliery in Qianxi County at 6:10 p.m. Tuesday when the flooding occurred. Six escaped and 14 were trapped, Xinhua reported. The rescuers managed to save two coal miners by 8:30 a.m. Wednesday, while eight were confirmed dead, including the colliery director and deputy director. And four remain missing. Longhua, a township-owned high-gas coal mine with annual designed output capability of 60,000 tons, is undergoing technology renovation to the goal of producing 300,000 tons of coal annually. The rescuing work is under way, together with the probe into the accident, the provincial administration for work safety supervision said.
