Ten miners were injured and six others were trapped after a gas explosion occurred early Sunday morning in southwest China's Sichuan Province, local authorities said.

The blast occurred in a coal mine in Rongxian County at about 7:30 a.m., a spokesman from the county's emergency response office said.

There were 28 miners working underground when the explosion happened, the spokesman said.

Rescue operations for the trapped miners are under way. The Sichuan Electric Power Corp. has dispatched 95 workers to the mine to carry out rescue operations and ensure a steady supply of electricity to the area.

The condition of the injured miners is not yet known.
