HARBIN, Dec. 5 (Xinhua) -- Eleven miners were still missing more than three days after a coal mine flooded in northeast China's Heilongjiang Province, rescuers said Wednesday.
As of 5 p.m. Wednesday, the undermine water level had declined by about 18 meters, said Li Shuguang, a rescue headquarters spokesman.
Over 28,000 cubic meters of water has been pumped out as rescuers try to increase the drainage capacity, said Li.
Rescuers have drilled a 40-meter-long hole planning to send oxygen and food to the miners.
"Although more than 90 hours have passed, we still hold hope for life," Li said.
A total of 22 miners were working underground when the accident happened at 11:40 p.m. Saturday at the Furuixiang Coal Mine in Qitaihe City.
Six miners escaped, with another two escorted out of the mine at noon Sunday before being taken to hospital. Three miners have been confirmed dead.
The cause of the accident is under investigation.
