Objective: To establish an evaluation model for occupational hazard prevention and control levels in coal mines, to explore the combination of Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation, to evaluate the overall situation of occupational hazard prevention and control in coal mines. Methods: In November 2021, Collect information of occupational hazards and their prevention and control status in 30 coal mines. AHP model was first constructed for the elements of occupational hazard prevention and control in coal mines. Then, the AHP and fuzzy comprehensive evaluation method was applied to comprehensively evaluate and grade the occupational hazard prevention and control in coal mines, using the principles of maximum membership and weighted average. Results: The hierarchical fuzzy comprehensive evaluation results for typical coal mine were basically consistent with its occupational hazard prevention and control situation. The dust prevention and control situation was good, the noise prevention and control situation is average, the occupational health monitoring situation was good, the occupational health management situation was average, and the overall level of occupational hazard prevention and control was good. Conclusion: The hierarchical fuzzy comprehensive evaluation model for occupational hazard prevention and control levels, combined with the principles of maximum membership and weighted average, can objectively evaluate and reflect the overall situation of occupational hazard prevention and control in coal mines.
目的： 建立煤矿职业危害防治等级评估模型，探讨层次分析法和模糊综合评估结合应用，评估煤矿职业危害防治整体状况。 方法： 于2021年11月，收集30家煤矿的职业危害及其防治状况信息，构建煤矿职业危害防治工作要素的层次分析模型，应用层次分析和模糊综合评判法对煤矿的职业危害防治进行综合评估分级，评估原则为最大隶属度原则和加权平均原则。 结果： 针对典型煤矿单位的层次模糊综合评判结果与单位的职业危害防治情况基本一致，粉尘防治情况良好，噪声防控情况一般，职业健康监护情况良好，职业卫生管理情况一般，职业危害防治等级整体良好。 结论： 建立的职业危害防治等级的层次模糊综合评判模型，结合最大隶属度原则和加权平均原则，能客观地评估和反映煤矿职业危害防治的整体情况。.
