摘　　要：主要研究永平铜矿在露天—地下联合开采期间,洞室群围岩在工程地质因素以及开挖、采矿、露天爆破、地应力等复杂条件作用下的状况。针对实际工程中存在的诸多模糊信息,利用层次分析法来建立综合评判体系,并运用模糊数学将定性和定量指标权重进行评价,最后由模糊矩阵得出了影响地下洞室群稳定性的主要因素和在各种影响因素下洞室群的岩体级别。The paper mainly studies the surrounding rock condition of underground group cavities under the influence of many factors such as excavation, underground mining, open blasting, ground stress, engineering geology and etc, during opencast-undergound combined mining at Yongping Copper Mine. Since there are much fuzzy and uncertain information in practical engineering, the synthetic evaluation system is established by analytic hierarchy process and the fuzzy mathematics method is used to assess the weight of quantitative and qualitative indexes. At last, the major influencing factors to the stability of underground group cavities and the rock grade under the influence of various factors are obtained by fuzzy matrices.
