摘要
基于未确知测度理论,建立了综放面火灾危险性等级评价和排序模型.从地质条件和工况出发,考虑影响综放面火灾的16项因素,根据实测数据建立了影响因素的未确知测度函数.该模型针对综放面火灾危险性评价中的诸多不确定性影响因素,根据实际情况,分别对其进行了定性、定量分析,利用熵计算各影响因素的指标权重,依照置信度识别准则进行等级判定,最后得出综放面火灾危险性的评价结果.该评价方法不仅能解决综放面火灾危险性评价中诸多因素的不确定性问题,还可以按危险程度进行排序.以该方法对山西阳煤4个综放面进行火灾危险性评价,结果表明,该方法科学合理,意义明确,可以在实际工程中进行推广应用.
Based on the uncertainty measurement theory, a fire risk - evaluating and order - arranging model of fully mechanized caving face is established. By considering the geologic condition and engineering status of fully mechanized caving face, 16 factors that influence the stability of fully mechanized caving face are taken into account. And uncertainty measurement function is obtained based on the in -situ data, According to the actual situation, the uncertainty problems in fire risk evaluation are solved by qualitative analysis and quantitative analysis respectively. Entropy theory is used to calculate the index weight of factors, and credible degree recognition criteria is established according to the theory uncertainty measurement. The results of fire risk evaluation are obtained with the credible degree criteria, and risk degree is arranged with the order. Meanwhile, the model is employed to evaluate 4 fully mechanized caving face in Shanxi yangmei, Compared with the results of fuzzy evaluation method, the results show that uncertainty measurement method is reasonable and can be applied to the actual engineering.
