摘要
为科学合理配置安全资源以及提高安全管理效率,以近3 a来的45起典型事故案例对一线矿工不安全状态进行分类研究。通过文献分析法提取了一线矿工不安全状态的5个特征;运用Hayashi数量化理论Ⅲ构建了一线矿工不安全状态判断矩阵,并采用SPSS 26.0软件对5个特征进行相关性分析;应用MATLAB R2018a软件制散点图,并使用SPSS 26.0软件进行聚类分析,将一线矿工不安全状态量化分类。结果显示:提取的5个变量相互独立;一线矿工不安全状态可分为有意内因型(第一类)、偏有意外因型(第二类)和无意外因型(第三类);三类一线矿工不安全状态的综合危险性由大到小依次为第三类、第二类、第一类。对于分类中每个事故中人的不安全状态的频率由大到小依次为第一类、第二类、第三类。研究结果有助于推进一线矿工不安全状态的分级管控。
In this paper,a literature analysis method is employed to extract the characteristics of unsafe state.The independence of variables is verified through the construction of a judgment matrix and correlation analysis.Additionally,MATLAB and SPSS software are utilized to create scatter plots and conduct cluster analyses.The aim is to study the classification of unsafe state among tier miners.Specifically,the characteristics of the unsafe state of five tier miners are first extracted.Hayashi's Quantitative TheoryⅢis then employed to construct a judgment matrix.Using SPSS software,correlation analysis is conducted to verify the mutual independence of the five variables.Additionally,scatter plots are generated using MATLAB software,and cluster analysis is performed with SPSS software to identify three types of unsafe state.The results indicate that the unsafe state of tier miners can be classified into three distinct categories.The first category is the intentional internal unsafe state,the second category is the accidental unsafe state,and the third category is the unintentional unsafe state.In fact,the unsafe state in these three types of tier miners arise from the combined influence of both group and individual characteristics.There are both direct and indirect relationships between the unsafe state and unsafe behaviors of the three types of tier miners.The complexity of the five characteristic states in the unsafe state of these miners,from highest to lowest,is as follows:the first category,the third category,and the second category.Therefore,the comprehensive risk associated with the unsafe state of the three types of tier miners,ranked from highest to lowest,is as follows:the third category,the second category,and the first category.In terms of the frequency of unsafe state observed in each accident,the classification from most to least frequent is:the first category,the second category,and the third category.The first category exhibits a high comprehensive risk,although its frequency is low.In contrast,the third category has a lower comprehensive risk but a higher frequency of occurrence.
