基于熵权物元可拓的采空区自燃危险性评价

Spontaneous Combustion Risk Assessment of Goaf Based on Entropy Matter-element Extenics Model

为了准确合理地对采空区自燃危险性进行评价,在传统的物元可拓评价模型基础上,融合了熵权法,建立了采空区自燃危险性评价的熵权物元可拓模型,通过熵权理论来确定权重,有效地克服了传统的物元可拓方法在评价的过程中选指标权重过于主观性的缺点,预测过程计算简便,将该方法应用于新集二矿采空区评价,研究结果表明:采空区自燃危险性评价结果与现场实际情况一致,为评价采空区自燃危险性提供了一条新的技术途径。

In order to evaluate goaf spontaneous combustion risk accurately and reasonable, establishes the goaf spontaneous combustion risk assessment of entropy matter-element extension model to determine the weight by entropy weight theory in the traditional model based on matter-element extension evaluation, combined with entropy weight method. This method overcomes the traditional method of matter-element extension too subjective when choosing index weight in the process of evaluation effectively.The process of calculation is simple, the method was applied to Xinji No.2 coal mine goaf and the results show that the goaf spontaneous combustion risk assessment result is consistent with the actual situation, and provides a new technical way to evaluate the goaf spontaneous combustion risk.
