CCTV says rescuers have located 12 of the 21 trapped miners.
Eight miners have been rescued and 21 remain trapped in a coal mine in China’s Xinjiang region after flooding cut power underground and disrupted communications, according to state media.
The accident happened in Fengyuan coal mine in Hutubi County on Saturday evening, when staff were upgrading the site, the official Xinhua news agency said.
Rescuers had located 12 of the 21 trapped miners, broadcaster CCTV said, but it was unclear if they were all together.
Rescue personnel were trying to pump water from the flooded shaft and have been piping air into the mine.
Pipes were being laid but the pumping operation was going to be challenging, 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 east China’s Shandong province after an explosion damaged the entrance, leaving workers stuck underground for about two weeks.
Eleven men were pulled out alive, 10 died and one miner remained unaccounted for.
In December, 23 miners died after being trapped underground in the southwest city of Chongqing – just months after 16 others died from carbon monoxide poisoning at another coal mine in the city.
