Abstract: In order to find out the human factors leading to coal mine general accidents, the paper counts the coal mine accidents occurred in 2019. Based on the investigation reports, HFACS is used to carry out the statistics and analysis of 43 coal mine general accidents. Then the relationships between different human factors, which are involved in the HFACS-PEFE framework, are identified by conducting chi-square test and odds ratio analysis. Four routes of coal mine general accidents are obtained. Among them, the route comprised of organizational process loopholes → invalid correction → individual mental state → habitual violation is the easiest way to lead to general accidents in coal mines. Finally, according to the analysis results, the measures to prevent coal mine general accidents are proposed.
