The government warned recently that China's mining industry, the most dangerous in the world, would see more accidents as output was boosted to provide heating fuel for the winter months.
Accidents in China's coal mines claimed the lives of more than 3,000 men in the first ten months of 2007; an average 13 deaths a day in fires, explosions and floods, despite government efforts to improve safety.
In August, 181 miners died when two mines flooded in eastern Shandong province after heavy rains.

Guizhou province, one of China's poorest regions, has already reported five gas leaks and explosions since August, according to state media.
