首先确定了影响煤层自燃的因素指标，并对它隶属于不同自燃等级的取值进行了无量纲化处理，采用模糊层次分析法确定了各个因素权重，利用可拓学理论建立了煤层自燃危险性判别模型。其次，以山东新汶矿业孙村煤矿十三层煤为例，采用模型方法对其自燃危险性进行了评价，所得结果与煤科院的自燃鉴定结论一致。上述研究不仅丰富了煤层自燃危险性评价方法，而且也为预防此类灾害起到了一定的参考和借鉴作用。%The influence factors of the spontaneous combustion of the coal seam are determined,and values of the factors,which belonged to different levels of spontaneous combustion,are normalized.By adopting fuzzy analyt-ical hierarchy process,the weights of every factor are determined and the discriminate model of the danger of the spontaneous of the coal seam is established by the extension theory.Taking the 13#coal seam in Shandong province Xin-Wen Mining Group CO.LTD of Sun-Cun Coal Mine as an example,the dangerous of the spontaneous combus-tion of the mine is evaluated by model method.The results obtained are accorded with the spontaneous combustion expert conclusion of the Mining Technology School.The researches above not only enrich the evaluation methods of the dangerous of the spontaneous combustion of the coal seam,but also provide references and lessons for the pre-vention of such disasters.
