China's coal mine production situation is grim and various types of accidents occur frequently, and gas explosion accidents are the highest incidence of coal mine accidents. The authors selected 200 gas explosion accidents of coal mine enterprises in recent years, and extracted a large number of workers' unsafe behaviors. Meanwhile, four working types related to gas explosion accidents were obtained, namely ventilation, gas prevention and fire extinguishing, blasting, and electrician. This article listed some influencing factors of unsafe behaviors and corrected the probability of unsafe behaviors. In addition, a probabilistic risk assessment model was established, and the Monte Carlo method was used to analyze the risks caused by unsafe behaviors of various working types. The results show that the risk of unsafe behaviors caused by the ventilation working type is the highest, followed by gas prevention and fire extinguishing, and finally blasting and electrician. This paper studies the influencing factors of miners' unsafe behaviors from the perspective of behavior, guarantees effectively the safety management of coal mine enterprises, and lays a foundation for studying unsafe behaviors related to coal mine gas explosions.
中国煤矿生产形势严峻，各类事故频繁发生，其中瓦斯爆炸事故是煤矿事故中发生率最高的。本文选取了近年来 200 起煤矿企业瓦斯爆炸事故，从中提取了大量的工人不安全行为，并得出与瓦斯爆炸事故相关的四种作业类型，分别是通风、瓦斯防治与灭火、爆破和电工。本文列出了一些不安全行为的影响因素，并对不安全行为的概率进行了修正。此外，建立了概率风险评估模型，并采用蒙特卡罗方法分析了各作业类型不安全行为所引起的风险。结果表明，通风作业类型引起的不安全行为风险最高，其次是瓦斯防治与灭火，最后是爆破和电工。本文从行为角度研究了矿工不安全行为的影响因素，为煤矿企业的安全管理提供了保障，为研究与煤矿瓦斯爆炸相关的不安全行为奠定了基础。
