基于SEM的煤矿安全生产影响因素系统研究

Study on factors influencing coal mine work safety based on SEM

为正确认识影响煤矿安全生产的各因素及其对安全系统的相对重要性,首先运用文献综述法和现场调研法,系统考虑并提炼出影响煤矿安全生产的5大类18个因素;然后选取2个煤矿的300名员工发放问卷,应用SPSS21.0统计分析数据;最后运用结构方程模型（SEM）建模方法,构建二阶验证性因子分析模型和因果关系路径分析模型,分析影响煤矿安全生产的5大类因素以及各因素间的关系。结果表明：人的不安全行为对煤矿安全生产的影响最大,其次是组织管理、物的不安全状态、煤矿固有风险和环境中的不安全因素;另外,5大类影响因素之间具有直接或间接的影响。

It is very important to correctly understand the factors affecting coal mine work safety and their relative importance to the safety system. First,18 factors divided into 5 categories were identified with the method of literature review and field research. Then,300 employees from 2 coal mines were selected to carry out the questionnaire survey,and SPSS21.0 was used to analyze the questionnaire data. Finally,a second-order confirmatory factor analysis model and a causal relationship path analysis model were built by the method of SEM,and the relationships between the five factors were analyzed. The results show that human unsafe behaviors have the greatest impact on coal mine work safety,followed by the unsafe factors in organizational management and unsafe status of articles,coal mine inherent risk and the unsafe factor in the environment. In addition,there is a direct or indirect impact between the 5 factors.
