【摘要】 通过AHP和模糊数学方法建立了评价下向水平分层胶结充填法充填前采空区稳定性的评价模型。采用德尔菲法对采空区稳定性的影响因素进行了分析,构造了判断矩阵,通过层次分析法确定了各影响因素的权重;结合采空区四值逻辑评分表和定量表述的采空区灾害危险度的影响因素的隶属函数确定表确定了各影响因素的隶属度,建立了评判矩阵。并对某矿山采空区进行稳定性判断,最终得出该采空区稳定性为Ⅱ级,属于较稳定级别。更多还原

【Abstract】 By analyzing AHP and fuzzy comprehensive evaluation theory,an evaluation model was established to evaluate the stability of Mined-out Area.Delphi method was used to analyze the factors affecting the stability of the Mined-out Area,and the judgment matrix was constructed,The weight of each factor was determined by analytic hierarchy process.The membership degree of each factor was determined by the membership function determination table of the influential factors of the Mined-out Area hazard risk,and the evaluation matrix was established and a stability judgment for certain mine Mined-out Area was conducted,finally it was concluded that the stability of mined-out area toⅡ belonged to a relatively stable level.更多还原
