A worker trapped in a Chinese gold mine for more than a week has died as rescuers tried to clear debris and improve ventilation to save 21 others also stuck deep below ground, state media CCTV reported Thursday.
Rescuers have been in contact with 11 workers trapped in one chamber and have delivered food, medicine and other supplies to them. State broadcaster CCTV said one of them had suffered a head injury in the initial explosion and lapsed into a coma before dying.
Two other workers in that group were described as being in poor health. Another was reportedly alive in a nearby chamber, but the fate of another 10 workers remains unknown.
The reports said exhaustion has set in among some of the workers since the Jan. 10 explosion ripped through the mine that was under construction in Qixia, a jurisdiction under Yantai in the eastern province of Shandong.
Rescuers were attempting to clear cages, skips and other debris blocking the main shaft while drilling other shafts for communication, ventilation and possibly to lift workers to the surface. Boring has reached depths of around 700 meters (about 2,000 feet), the reports said.
Mine managers have been detained for waiting more than 24 hours before reporting the accident, the cause of which has not been announced.
Increased supervision has improved safety in China’s mining industry, which used to average 5,000 deaths per year. Yet demand for coal and precious metals continues to prompt corner-cutting, and two accidents in Chongqing last year killed 39 miners.
