Shanghai: Twenty two workers were killed in a coal mine accident in southwestern China, the official Xinhua news agency reported on Wednesday, the latest mining disaster to highlight poor safety standards in the world`s biggest coal producing country.
The accident, which occurred on Tuesday evening at the Yanshitai Coal Mine in Chongqing municipality`s Wansheng District, was caused by a "gas incident", Xinhua quoted regional authorities as saying.
A total of 28 miners were working at the time of the accident. Two miners were also injured, the report said.
Officials at state-owned Nantong Mining Co Ltd, which owns the mine, were not immediately available for comment.
China`s mines are the deadliest in the world because of lax enforcement of safety standards and a rush to feed demand from a robust economy. Two workers were killed in a coal mine accident in the northern province of Shanxi in January.
