3 killed, 6 missing after high levels of carbon monoxide detected in northwest mine
Local authorities said Thursday three miners had died of carbon monoxide poisoning, while six others remained missing in a lead-zinc mine in northwest China’s Gansu Province.
The Changba Lead-Zinc Mine near the city of Longnan said it failed to contact three staff conducting daily inspections in the mine at 9 a.m. Wednesday.
It later sent six inspectors underground Wednesday afternoon to check the situation. Two returned to the surface, reporting high levels of carbon monoxide in the mine.
As of Thursday morning, rescuers had retrieved three bodies and were trying to reach the six people still in the shaft.
Initial investigations found illegal operations had resulted in the elevated levels of the poisonous gas.
The mine belongs to Baiyin Nonferrous Metals Group Co Ltd., a major producer of nonferrous metals in China.
