摘要：为解决境界外驻留矿体的开采技术难题，综合运用物元概念的可拓学理论与层次分析法，建立多层次多指标的岩质边坡稳定性综合评价模型，对边坡稳定性进行评价，得出安全等级标准及评价指标量值。运用层次分析法确定影响边坡稳定性的安全评价指标的权重系数，根据可拓学理论构造经典域物元、节域物元和可拓集合中的关联函数，建立岩质边坡稳定性安全评价的层次分析法 可拓学模型，得到岩质边坡稳定性安全评价结果。经计算，岩质边坡稳定性综合安全评价的级别特征值为2.19，安全等级为I级，边坡稳定性处于极稳定状态。研究结果与矿山以往运用RMR法和BQ法计算的评价结果一致。 关键词：可拓学；层次分析法；评价模型；岩质边坡；安全等级

Abstract: In order to solve the mining technical problem of the orebody outside the boundary, the theory of extenics about the matter-element concept and the analytic hierarchy process (AHP) were applied to establish a multi-layer comprehensive evaluation model of rock slope stability, thus the slope stability was evaluated and the safety level standard and the evaluation index were obtained. Firstly, the weight vector about the safety index was determined by AHP which influenced the slope stability, the elements in classical and joint field, correlation function of matter elements in extension sets were structured by extenics theory, an AHP-extenics model of rock slope stability was set up with comprehensive evaluation and then the safety evaluation result of rock slope stability was obtained. Through the calculation of the model, the safety index is 2.19 and the security level is I, which means that the comprehensive safety level of the rock slope is hyper-stable. The research results are consistent with those of the RMR method and BQ method. Key words: extenics; analytic hierarchy process (AHP); evaluation model; rock slope; security level

据国内外有关资料统计，露天矿山开采结束后，残留在境界外的驻留矿体占总储量的5%~16%。对于马钢集团姑山矿业有限公司，解决露天铁矿驻留矿体开采技术难题，回收宝贵的驻留铁矿资源，实现驻留矿体的安全、高效、低成本开采，不仅可以消除姑山
