煤矿瓦斯爆炸事故不安全动作多维属性统计及特征分析OACSTPCD

Gas explosion accidents are the most serious type of accidents that cause losses in coal mines.In order to explore the pat-tern of unsafe actions related to such accidents and to regulate the behaviors of relevant work types in the operation process of under-ground 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 Coal Mine Safety Regulations.
