基于可拓理论，建立了采空区煤炭自燃危险性评价物元模型，采用简单关联函数确定评价指标权重。确定了采空区煤炭自燃危险性评价指标及等级量值范围，依据山西某矿15101工作面实际，结合现场和实验室相关参数测定，获取了待评物元样本，对采空区自燃危险性进行了物元可拓评价。结果表明：该模型评价结果与实际情况相符，采用动态客观权重确定方法能有效避免主观因素的影响，将物元模型应用于采空区煤炭自燃危险性评价是合理可行的。

Based on the extenics theory , the matter element model used to evaluate goaf coal spontaneous combustion risk was established ,and the subjective dynamic weight about evaluation index was determined by simple dependent function method .The evaluation indexes and their level value ranges were constructed .The indeterminate sample was obtained by the actual conditions in 15101 work face of a coal mine in Shanxi Province and the field and laboratory test results ,and the sample was evaluated by matter element model .The research show that the evaluation result agrees well with the practical situations ,and the determination of subjective weight can avoid the effect of human subjective factor .It is reasonable and feasible in evaluating goaf coal spontaneous combustion risk by matter element model .
