Seven coal miners have died and four more are missing following the third deadly accident to strike China's mining industry in a week.
A statement from the local propaganda department said rescuers are still trying to reach people trapped underground after the Monday night gas explosion in Hubei province.
Rescue workers are pumping air into the mine shaft to aid the rescue effort.
The accident takes the total number of mining deaths this week to 60.
China is the world's top producer and consumer of coal and deadly workplace events occur frequently despite a stated public commitment to improving worker safety.
