摘　　要：为准确评估煤自燃危险性,有效预防矿井火灾的发生,通过分析煤自然发火影响因素,确定指标范围,划分自燃危险性等级,在传统逼近理想解排序法(technique for order preference by similarity to an ideal solution,TOPSIS)和单一物元可拓法的基础上加入熵权计算,提出了TOPSIS-物元可拓联用评价方法,建立了煤自燃危险性评价体系。将模型应用于现实生产状况,分析了某矿井的8个不同煤层的自燃危险性,计算得到总体评价与分层次评价结果。研究表明:各评价对象的模型计算结果与实际情况基本一致,应用结果验证了所构建模型的可行性,对矿井火灾的预防和治理具有重要参考价值。To accurately evaluate the spontaneous combustion risk of coal and effectively prevent the occurrence of mine fires,the range of indicators was determined and the spontaneous combustion hazard level was classified by analyzing the influencing factors of the spontaneous ignition of coal.Moreover,technique for order preference by similarity to an ideal solution(TOPSIS)-matterelement extension was proposed and evaluation system of coal spontaneous combustion risk was established in which the entropy weight calculation based on traditional TOPSIS and single matter-element extension method was taken into consideration.The model was used to realistic production conditions to analyze the spontaneous combustion hazard of eight different coal seams in a certain mines,and the overall evaluation and hierarchical evaluation results were calculated.Results show that the model calculation results of each assessment object are basically the same as the actual situation,and the application results prove the feasibility of the model,which is an important reference value for the prevention and administration of mine fires.
