Two miners were killed and another injured in a coal mine cave-in in northwest China's Xinjiang Uygur Autonomous Region, according to local sources on Sunday.

The collapse took place at the shaft of a coal mine affiliated to Hutubi County Water Supply and Heating Company at about 7:20 PM on Sunday when 13 miners were working inside the coal mine, said sources from Changji Hui Autonomous Prefectural Committee of the Communist Party of China (CPC).

One miner was crushed to death by the fallen debris on the spot, two others were seriously injured. One of the seriously injured died shortly after he was pulled out. Other workers escaped unhurt.

The other seriously injured one remains in hospital but has been out of danger, according to the sources.

Cause of the collapse is under investigation.

The coal mine only has an annual production capacity of 30,000 tons.
