摘　　要：为了避免露天煤矿外排土场采用单一的定量评价手段难以考虑定性影响因素导致影响其稳定性的情况;采用定性和定量多指标结合的综合评判手段,通过AHP(层次分析法)与FCE(模糊综合判别法)建立综合12种影响外排土场边坡稳定性的定性与定量指标综合评判的数学模型;对某露天煤矿外排土场边坡使用基于AHP法的YAAHP软件确定指标权重,代入到FCE模型中,经连续及离散型隶属度函数计算形成计算矩阵,进行稳定性评价;并采用Slide数值模拟软件对AHP-FCE模型结果进行验证。结果表明:该外排土场边坡处于一般稳定状态,验证所得结论与综合判别法结果基本一致。In order to avoid the situation where a single quantitative evaluation method is difficult to consider qualitative influencing factors that may affect the stability of the external dump of open-pit coal mines,the article uses a comprehensive evaluation method that combines qualitative and quantitative multiple indicators,establishes a mathematical model through AHP(Analytic Hierarchy Process)and FCE(Fuzzy Comprehensive Discrimination Method)to comprehensively evaluate 12 qualitative and quantitative indicators that affect the stability of external dump slopes.The YAAHP software based on AHP method is used to determine the indicator weights for the slope of an open-pit coal mine external dump.The weights are inserted into the FCE model and a calculation matrix is formed through continuous and discrete membership functions,so stability evaluation is carried out;and validate the AHP-FCE model results using Slide numerical simulation software.The results show that the slope of the external dump is in a generally stable state.Subsequently,the results of the AHP-FCE model are validated using Slide numerical simulation software,and the conclusion obtained from the verification is basically consistent with the results of the comprehensive discrimination method.
