2.3.2. Safety

The main safety statistic is the fatality rate per Mt. Over the last five years, the number of accidents and fatalities has decreased as production levels have increased (Table 4 and Figure 10). The causes of these fatalities are shown in Figure 11.

The major coal mining hazards facing Chinese coal mines include strata stability, high gas emission, outbursts of coal and gas, spontaneous combustion of coal and water inrush. As mining depth increases, rock stress, rock temperature and gas in coal increase, some existing hazards such as strata stability, gas emissions and outbursts of coal and gas will become more severe, and new hazards such as heat and rock bursts will emerge.

There is no doubt that coal mining in China will face some serious challenges in managing these hazards.
