Rescue forces have identified 12 out of 21 trapped miners, CCTV said.
Eight miners were rescued and 21 are still trapped in a coal mine in China’s Xinjiang region after floods cut off power underground and disrupted communications, state media said.
The accident happened at the Fengyuan coal mine in Hutubi district on Saturday night, as employees were upgrading locations, the Xinhua News Agency said.
CCTV said rescuers have identified 12 out of 21 trapped miners, but it is not clear if they were together.
Rescuers are trying to pump water from the flooded shaft and has led gas into the field.
The pipes are already in place but pumping will face challenges, CCTV said.
Mining accidents are common in China, where the industry has a poor safety record and enforcement of regulations is often lax.
In January, 22 workers were trapped in a mine in eastern China’s Shandong province after an explosion damaged the entrance, trapping workers underground for about two weeks.
Eleven men were dragged out alive, 10 died and a miner has yet to be traced.
In December, 23 miners died after being trapped underground in the southwestern city of Chongqing – just months after 16 others died of carbon monoxide poisoning at another coal mine in the city.
