Two people are still trapped underground in the latest of a series of accidents at mines in China.

Fourteen miners were killed on Tuesday in a coal and gas blast at a mine in southwest China, with two people still trapped underground, authorities said.

The accident in the early hours of Tuesday is the latest in a series of mining incidents in China, where safety regulations are often poorly enforced.

Two people were still trapped underground after the explosion at Guanglong coal mine in Guizhou province, the Southwest Guizhou Autonomous Prefecture government said.

Seven workers were lifted to safety after the accident and rescue work was continuing, according to local authorities.

The accident in Guizhou came days after flooding in a mine in southwest China’s Sichuan province killed five and trapped 13 miners underground.

State broadcaster CCTV said 347 miners were working underground at the Shanmushu coal mine owned by Sichuan Coal Industry Group in Gongxian county when the mine flooded on Saturday.

Last month at least 15 were killed in a blast in north China’s Shanxi province, which an official said was caused by activity that “broke the law and regulations”.

At a meeting in November, the State Council – China’s cabinet – ordered a “special crackdown on production-related safety issues” to “further improve workplace safety”, state media reported.
