瓦斯爆炸事故是煤矿各类事故中造成损失最严重的事故类型。为探究此类事故相关不安全动作发生的规律以及规范煤矿井下相关工种操作过程中的行为，对2005—2022年的116起煤矿重特大瓦斯爆炸事故进行了统计及分析；探讨了煤矿瓦斯爆炸事故中不同维度下的不安全动作分布特征，讨论了其出现的原因，并提出了针对性措施。结果表明：从工种作业类型和事故地点耦合的方面分析，爆破作业人员和瓦检作业人员分别在掘进工作面和采煤工作面不安全动作次数最多；从工种与法律法规的耦合方面分析，爆破作业人员是违反法规频数最多的作业人员，违反最多的法规为《煤矿安全规程》。

Gas explosion accidents are the most serious type of accidents that cause losses in coal mines. In order to explore the pattern of unsafe actions related to such accidents and to regulate the behaviors of relevant work types in the operation process of underground coal mines, 116 serious gas explosion accidents in coal mines from 2005 to 2022 were statistically analyzed to explore the distribution characteristics of unsafe actions in different dimensions of gas explosion accidents in coal mines, to discuss the reasons for their occurrence, and to put forward targeted measures. The results show that: from the aspect of the coupling of work type and accident location, blasting operators and tile inspection operators have the highest number of unsafe actions in the face of digging and coal mining, respectively; from the aspect of the coupling of work type and laws and regulations, blasting operators are the operators with the highest frequency of violating the regulations, and the most violated regulations is the.
