At least eight miners were killed and another missing after a coal mine blast in north China's Shanxi Province, the local government said on Saturday.
The blast happened around noon on Friday at the Xinmin Coal Mine in Linxian County, according to the provincial work safety administration.
Initial investigations showed the blast was possibly caused by explosives, Xinhua news agency reported.
Provincial work safety officials have gone to the mine to organise rescue operations that are still underway.
On Tuesday, a coal mine blast had killed at least 29 miners and injured 19 others in northwest China's Gansu Province.
China is the world's large st coal producer and consumer. However, Chinese coal mines are considered the deadliest due to high rates of accidents. On an average, 12 miners die every day in Chinese coal mines.
