摘要
针对采空区失稳坍塌的复杂性与不确定性,确定影响采空区稳定性的17个主要因素并确定各个因素所占的权重,建立并应用二级模糊综合评价模型对采空区稳定性进行定量分析。研究结果表明:应用模糊数学理论建立的二级模糊综合评价模型能够较准确地反映采空区稳定性程度,与实际情况较符合,为矿山地下采空区的稳定性程度评价提供了一种可行的思路和方法。
In view of the complexity and uncertainty of the collapse of goaf,seventeen main factors that affect the stability of goaf are determined and the weight of each factor is determined.The second-level fuzzy comprehensive evaluation model is established and applied to the stability of goaf Sexual Quantitative Analysis.The results show that the second-level fuzzy comprehensive evaluation model established by the fuzzy mathematics theory can more accurately reflect the degree of stability of goaf,which is in line with the actual situation and provides a feasible evaluation for the stability degree of underground mined-out area ideas and methods.
