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 from four aspects: the type of coal mine enterprises, the type, grade, and 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, bar chart and percentage chart, and an in-depth analysis was conducted to explore the underlying causes of these occurrences. The analysis results show that the thermal power disaster accidents in coal mines in China have gradually decreased in the past 12 years, which mainly in the form of gas explosion, and mostly in the form of large accidents and major accidents. The township coal mines and state-owned coal mines have experienced significant losses, indicating a dire situation. The southwest and northeast regions of China exhibit a higher incidence of accidents. Finally, according to the analysis results, the corresponding preventive measures are put forward from the aspects of policy, enconomy, supervision, region and technology.
