Abstract: Abstract: In order to analyze the occurrence regularity and characteristics of coal mine accidents in China, according to the statistics of coal mine accidents from 2013 to 2017, the occurrence regularity and characteristics of coal mine accidents in China in the past five years were revealed through the number of coal mine accidents, the number of deaths histogram, scatter plot, radar plot and the occurrence of various coal mine accidents. Therefore, the frequency of accidents and transportation accidents is high, accounting for 56.55% of the number of coal mine accidents; the roof accident rate is the highest, 2.23 times of the transport accident, 3.49 times of the gas accident, accounting for the main part of coal mine accidents, easily overlooked other accidents have a rebound trend; gas, roof, mechanical and electrical accident mortality is high, accounting for about coal mine accident death. 70% of the total number of deaths, gas accidents have a wide range of impact, accounting for the main part of the number of deaths in coal mine accidents, is 2.4 times the number of deaths in roof accidents; with the number of gas, roof and mechanical and electrical accidents decreased, the number of deaths in accidents also decreased accordingly. Gas accidents are sprinkled in a wide range, the number of fatalities in a single accident is more, with an average of 5.22 deaths in each accident, and 1.32 deaths in each roof accident, with an average of 1 deaths in each accident. In-depth analysis of the causes of coal mine accidents in China, and put forward effective prevention and control measures, coal mine safety management to provide a strong support.
