CHANGZHI, Shanxi - A team of 80 volunteers finished a 48 hour stay in an emergency refuge chamber in a coal mine on Sunday to test the capacity of the underground rescue facility.
Considered the most advanced coal mine refuge shelter in China, the rescue chamber in the Changcun Mine in Changzhi city, North China's Shanxi province, is equipped with oxygen, electricity, and telecommunication equipment, and a permanent borehole connects it to the outside world, allowing air, fresh water and food to be lowered down.

The widespread use of this refuge chamber will greatly improve the safety of the country's coal mines, Jin said.
