Ten people have died from a gas leak at Xinhua coal mine in south-west China's Guizhou province in the early hours of 11 June.
A total of 130 workers were working at the underground coal mine at the time of the accident, of which 120 managed to escape, reported state news agency Xinhua.
According to local authorities in Liupanshui City, the gas leakage occurred just after midnight. Rescue workers have retrieved the bodies of those killed.
The mine is owned by Guizhou Hualong Coal Industry, a joint venture between a local coal firm and the China Resources Power Holdings.
The incident comes one week after a gas accident at Yanshitai coal mine in China's south-western municipality of Chongqing, caused the deaths of 22 workers.
This accident is the latest in a series of mining disasters in China, highlighting the poor safety standards of the country, which is considered to be the biggest coal-producing nation in the world.
Last month, the Chinese Government announced plans to close more than 2,000 small-scale coal mines by 2015, to improve safety and address pollution issues.
Coal mines reported to be among the primary targets include Liaoning, Heilongjiang, Jiangxi, Hubei, Hunan, Sichuan, Yunnan and Guizhou provinces, along with Chongqing municipality.
