为了解决实际中抽象的语言模糊问题,便于将各种安全隐患进行比较,利用语言变量转化尺度为基础的模糊层次分析法,以煤矿管理和作业人员的主管感受为出发点,通过转化尺度将主观评价定量化,然后2次进行层次分析求各安全隐患的相对重要性权重和相对发生频率权重,进而获得安全隐患的风险排序,为采取有效措施进行煤矿安全治理提供参考。
In order to solve the practical problem of abstract language ambiguity, it is easy to compare various potential safety hazards. Based on the fuzzy analytic hierarchy process (AHP) based on the linguistic variable conversion scale, taking the coal mine management and workers’ supervisor as the starting point, the subjective evaluation Quantified, and then analyzed the levels twice to find the relative importance weight and the relative frequency weight of each potential safety hazard, and then got the risk ranking of potential safety hazards, so as to provide reference for taking effective measures for coal mine safety governance.
