Seven people were killed in a coal mine gas explosion in northeast China's Liaoning province, local officials said on Sunday.
The blast occurred at the Xinfa coal mine in Fuxin City on Saturday evening when 34 miners were working underground, an official with the Liaoning coal industry administration said.
Twenty-seven miners managed to escape safely, but seven others died in the accident, said the official, adding rescuers have retrieved the bodies.
Authorities are investigating the cause of the blast at the licensed coal mine.
A total of 1,792 coal miners died in 1,066 mishaps in China, the world's top coal producer and consumer, during the first half of this year, the government said earlier this month.
In 2006, coal mine accidents killed 4,746 people in China with an average of 13 deaths per day.
