Abstract

In order to make an overall macro-level assessment of accident risks in all coal-producing provinces of China, and to analyze the characteristics of accident changes, and to collect data on domestic coal mine accidents during the period of "13th five-year", from the aspects of coal mine accident type, casualty, time, space and region, this paper analyzes the change of whole coal mine safety situation by mathematical statistics, extension theory and other mathematical methods. The results show that roof accident takes the place of gas accidents as the main accident type, and the accident area is shifting from south to north. The proportion of accidents in state-owned coal mines increased, and more larger size accidents happened in the township coal mine. There are many coal mines, a high death rate of one million tons and complicated geological conditions in the provinces with frequent accidents. Reform of mining institutions and strengthening the main responsibility of enterprises for production safety plays an active role in promoting mine safety production. The change in coal mine accident types, and the establishment of domestic disaster management investment, standard-setting and risk monitoring and early-warning system of coal mine safety production, and the elimination of small and backward coal mines have a strongly coupled correlation. Based on the analysis of extension theory, the overall risk level of coal mine accidents in the early period of the "13th five-year" is three, by the end of the "13th five-year", the overall coal mine accident risk level is two, the overall safety situation tends to be good. © 2022 China Safety Science Journal.
