摘　　要：为了对煤矿顶板事故风险进行有效评价,构建顶板事故风险评价指标体系,并运用层次分析法确定了顶板事故风险影响因子的权重。运用集对分析建立风险评价模型,并结合灰色关联度确定集对分析所需的差异度系数,从而得出绝对联系度。根据取值所在的安全区间分析顶板事故的风险等级及未来发展的趋势,提出需要整改和加强的措施。此方法解决了单一集对分析联系度不确定的问题,探索了一条新的顶板事故风险评价的途径,为煤矿的安全管理和事故预防提供了有效支持。In order to evaluate roof accident risk of coal mine effectively, an evaluation index system of roof accident was built, and the weighting of influence factors of roof accident was confirmed by AHP. A risk evaluation model was built with set-pair analysis, and the diversity factor coefficient of set-pair analysis based on gray relational degree was confirmed, and then absolute relative degree was obtained, and risk degree and development trend of roof accident according the safety interval that the value belong to, the rectification and strengthen method were put forward, a new method of roof accident risk assessment was explored, it provided effectively supporting for safety management and accident prevention.
