Abstract: Based on the statistics of national coal mine thermal power disaster accidents from 2011 to 2022, the data statistics method was used to comprehensively analyze the four aspects of the nature of coal mine enterprises, the type of coal mine thermal power disaster accidents, the grade of coal mine thermal power disaster accidents and the occurrence area of coal mine thermal power disaster accidents. The law and characteristics of coal mine thermal power disaster accidents were displayed by trend chart, histogram and percentage chart, and the causes of coal mine thermal power disasters were analyzed in depth.The analysis results show that the thermal power disaster accidents in coal mines in China have gradually decreased in the past 12 years, mainly in the form of gas explosion, mostly in the form of large accidents and major accidents. Township coal mine and state-owned coal mine casualties serious losses, the situation is grim ; southwest and northeast regions are accident-prone areas. Finally, according to the analysis results, the corresponding preventive measures are put forward from the policy,economic, regulatory, regional and technical levels.
