摘要
传统的煤矿火灾评价手段存在主观性强、评价指标不全面等问题,评价结果难以量化和横向比较,影响了火灾评价结果的客观性和准确性。针对上述问题,提出一种基于层次分析法(AHP)-模糊综合评价法(FCE)的煤矿火灾风险评价方法。针对煤矿火灾特点,构建了以“人、机、环、管”4个因素为一级指标,动火作业人员是否持动火证并接受培训、工作面推进度、回风隅角CO浓度、胶带附近浮煤是否及时清理等31个因素为二级指标的火灾指标评价体系;采用AHP确定2级指标的权重,指出“机”和“环”对火灾风险的影响较大;采用FCE计算矿井火灾风险评价向量,给出火灾风险综合评价值四色分级预警结果,并给出了二级指标的评分依据。基于乌东煤矿多次实时监测数据,采用基于AHP-FCE的煤矿火灾风险评价方法对该矿火灾风险进行评价,结果表明:乌东煤矿火灾风险较低,火灾风险为蓝色,与工程实际一致,证明了该评价方法具有较高的准确度。
Traditional coal mine fire assessment methods are highly subjective and lack comprehensive evaluation indicators,making the results difficult to quantify and compare across cases,which affects their objectivity and accuracy.To address the above issues,a coal mine fire risk assessment method based on the Analytic Hierarchy Process(AHP)and Fuzzy Comprehensive Evaluation(FCE)was proposed.Based on the characteristics of coal mine fires,a fire risk assessment system was constructed,with four first-level indicators—Personnel,Equipment,Environment,and Management—and 31 second-level indicators.These included whether hot work personnel held valid permits and received training,the progress of the working face,CO concentration in the return air corner,and whether floating coal near the belt was promptly cleaned.AHP was used to determine the weights of the second-level indicators,indicating that Equipment and Environment had a greater impact on fire risk.FCE was applied to calculate the fire risk assessment vector of the mine,and a four-color graded early warning result was provided for the comprehensive fire risk assessment value,along with the scoring criteria for the second-level indicators.Based on multiple sets of real-time monitoring data from the Wudong Coal Mine,the AHP-FCE-based fire risk assessment method was used to evaluate the mine's fire risk.The results showed that the fire risk at Wudong Coal Mine was low and classified as blue,consistent with engineering practice,demonstrating that the proposed assessment method had high accuracy.
