基于2011—2022年全国煤矿热动力灾害事故的统计结果，采用数据统计法，按照煤矿企业性质、事故类型、事故等级和发生地区等4个方面进行综合分析，通过趋势图、柱状图及百分比图对煤矿热动力灾害事故的规律和特点进行总结，并对煤矿热动力灾害发生的原因进行深入分析。分析结果表明：近12年我国煤矿热动力灾害事故逐渐减少，以瓦斯爆炸类型为主，多以较大事故和重大事故的形式发生；乡镇煤矿企业和国有煤矿企业伤亡损失严重，情况严峻；西南地区和东北地区为事故多发地区。根据分析结果，从政策、经济、监管、企业及技术层面提出了相应的预防措施。

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.
