China has the world's deadliest mines, although the safety record has been improving in recent years as regulators have strengthened enforcement of safety rules.
Xinhua said the pit is mined by Dahuangshan Yuxin Coal Mining Co. Ltd., owned by the sixth agricultural division of the Xinjiang Production and Construction Corps.
