基于HFACS的煤矿一般事故人因分析

Human factor analysis of general accidents in coal mines based on HFACS

为了找出导致煤矿一般事故发生的人为因素,对2019年我国发生的煤矿事故进行了统计,并基于43起煤矿一般事故的调查报告,采用HFACS开展煤矿一般事故分析;然后采用卡方检验和让步比分析确定了HFACS上下层次间的相关性,得到4条煤矿一般事故发生路径,其中"组织过程漏洞→无效纠正→个体精神状态→习惯性违规"是煤矿一般事故的最易发生的途径;最后根据分析结果,提出了预防煤矿一般事故的措施。

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.
