CCTV says rescuers have found 12 of the 21 trapped miners.
State media reported that eight people had been rescued and 21 were trapped in a coal mine in China’s Xinjiang region after an underground power outage caused flooding and disrupted communications.
The accident happened at the Fenguan Coal Mine in Hutubi County on Saturday evening, while workers were improving the site, the official Xinhua News Agency reported.
According to broadcaster CCTV, 12 of the 21 workers trapped by rescuers were located, but it is not clear if they were all together.
Rescuers were trying to pump water from the ditch like a flood and blowing air into the mine.
The pipes are being laid but the pumping operation is going to be challenging, CCTV reported.
Mining accidents are common in China, where the safety record of this industry is very low and regulations are often enforced.
In January, 22 workers were trapped after an explosion damaged an entrance in the eastern Chinese province of Shandong, and workers were trapped underground for about two weeks.
Eleven were pulled alive, 10 died and one miner remained unaccounted for
In December, 23 miners died after being trapped underground in the southwestern city of Chongqing – just months after 16 people died of carbon monoxide poisoning at another coal mine in the city.
