Seven miners were trapped in a colliery gas explosion in
northeast China's Heilongjiang Province on Monday, the local
government said Tuesday.
The blast occurred at 4:30 PM at Hongyuan mine in Jidong County
in Jixi City, a spokesman with the provincial coal mine safety
watchdog said.
He said 29 miners were working in the pit when the accident
occurred and 22 were rescued.
Rescuers are continuing to search for the seven missing.
Investigators said Hongyuan was a small mine designed to produce
60,000 tons a year. It was allowed to resume production only in
April after a major safety overhaul.
