摘    要:对某大型矿山采空区稳定性进行分析。运用多级模糊评判理论,结合某矿山采空区工程地质资料选取15个评判因子,采用专家评定法和三相线性隶属函数分别对离散性和连续性变量因子进行评价,并采用计算机反演权重,建立矿山采空区稳定性的二级模糊综合评判模型。研究结果表明:采用所建立的模型所得评判结果能较准确地反映采空区的稳定程度,精度较高,为矿山采空区稳定性评价提供了一种可行的思路和方法。

Abstract: In order to analyze the stability of a big mine gob area, choosing 15 genes from the data of engineering geology of a gob area, using multi-stage fuzzy synthetic judgment theory and calculating the inversion of the weight with computer, the two-stage fuzzy synthetic judgment model of the stability of mine gob area was made using expert evaluation method and three-phase linear membership function method to evaluate discreteness variable and continuity variable. The results show that the results obtained by the model proposed reflect the practical situation of the stability after analyzing a sample of gob area, the model has high precision, and is practicable and feasible. The model can be used as a practical approach for stability analysis of gob area.
