7 dead in NE China mine accident
黑龙江东宁一煤矿发生气体中毒事故已确认7人遇难
HARBIN, Jan. 30 (Xinhua) -- Three workers have been pulled to safety and another three remain trapped after a coal mine accident killed seven in northeast China's Heilongjiang Province, authorities said Wednesday.
The three were lifted out of the mine at around 11 a.m. Wednesday and were in stable condition, according to the Dongning County government.
Three workers entered the Yongsheng colliery to pump out water, but poisonous gas caused them to faint around 10:30 a.m. Tuesday.
Rescuers were sent to the site, but some of them were also affected by the toxic gas.
A total of 12 people have been lifted out of the mine, but seven of them died despite medical treatment.
Rescue work is still underway.
Rescuers said the poisonous gas may have been carbon monoxide.
The private, licensed mine has an annual capacity of 50,000 tonnes.
