Abstract:
In order to further analyze the characteristics and rules of coal mine safety accidents in China, based on the statistics data of the number of coal mine accidents and fatalities from 2008 to 2021, the coal mine safety accidents in China were analyzed from four dimensions, including accident region, accident grade, accident type and accident time. The mortality rate per million tons for 2022 and 2023 was projected. The results show that coal mine safety accidents are more in the north and less in the south, and more in the southwest. Among the accidents of different grades, the number of common accidents is the most and the death toll is the least. The number of major accidents is small, but the death toll is the largest. In terms of accident types, roof accident, gas accident and transportation accident are the main types of coal mine safety accidents in China. From the point of view of the accident time, the number of accidents from January to March is relatively less, and the number of accidents from July to October is more.
