耦合效应下的煤矿顶板事故风险因素评价研究

Research on risk factor evaluation of coal mine roof accident under the coupling effect

在考虑人为因素、设备因素、环境因素和管理因素间的交互耦合效应的基础上,通过N-K模型量化煤矿顶板事故风险因素的耦合效应,建立加权直觉模糊集决策矩阵,并结合TOPSIS模型构建煤矿顶板事故风险因素的评价模型。对我国2008-2018年发生的185起典型煤矿顶板事故进行实例分析,总结出主观的人为因素或管理因素是煤矿顶板事故风险中更活跃的因素,与客观的设备因素或环境因素耦合易引发煤矿顶板事故,且人为因素比管理因素的影响更为关键。

Based on the interaction and coupling effect of human factors,equipment factors,environmental factors and management factors,the N-K model was used to quantify the coupling effect of risk factors of coal mine roof accident,the weighted intuitionistic fuzzy set decision matrix was established,and by combining TOPSIS model,the evaluation model of risk factors of coal mine roof accident was constructed.Through the analysis of 185 typical coal mine roof accidents occurred from 2008 to 2018 in China,it is concluded that subjective human factors or management factors are the more active factors in the risk of coal mine roof accidents,the subjective factors coupling with objective factors are liable to cause coal mine roof accidents,and human factors are more critical than management factors.
