An explosion in a coal mine in eastern China has trapped 29 workers underground, state media have reported.
About 30 rescuers were trying to reach those trapped in the private mine in Huainan city in Anhui province but were awaiting the arrival of heavy rescue equipment, China Central Television said.
Ten other miners managed to escape, one of whom was injured.
The government had ordered the mine shut down twice in June, but it had continued operating. Most of the trapped miners were in their 40s, it was reported.
