At least four miners were trapped after a colliery in Shanxi Province in north China was flooded Friday morning, the provincial coal industry regulator said.

Torrential floods gushed into a pit of the Xiguo Xinxing Coal Mine at about 2:20 a.m., trapping four miners working underground, according to the Shanxi Provincial Coal Mining Supervision Administration.

The mine is in a mountainous area more than 200 kilometers southwest of Taiyuan, the provincial capital.

The state-owned colliery, in Puxian County of Linfen City, has a designed annual production capacity of 300,000 tonnes.

Rescuers were trying to pump water from the shaft.
