Fatalities were among 24 people trapped underground by excessive carbon monoxide gas levels at the Diaoshuidong coal mine.
At least 18 people have died after being trapped in a mine in China’s southwestern city of Chongqing; the official Xinhua news agency said on Saturday, the region’s second such accident in just over two months.
The dead were among 24 people trapped underground by excessive carbon monoxide gas levels at the Diaoshuidong coal mine, the agency said, adding that one survivor had been rescued while search efforts continue.
Friday’s incident, which occurred at about 5 pm (09:00 GMT) in a mine shut for more than two months as the company dismantled underground equipment, is being investigated, it added.
China’s mines are among the world’s deadliest, with 16 deaths reported in late September after high carbon monoxide-trapped miners at the Songzao coal mine in Chongqing.
Diaoshuidong, built-in 1975 and run since 1998 as a private enterprise, is a high-gas mine with an annual capacity of 120,000 tonnes of coal, Xinhua said.
In 2013, three people were killed and two injured in a hydrogen sulfide poisoning incident at the mine, it added.
