中文摘要：
针对永平铜矿采矿过程中形成的复杂硐室群,利用FLAC~（3D）建立了两种不同巷道布置方式的模型,从开挖后的塑性区、位移和应力方面分析结果并进行比较。研究表明：出矿横巷和出矿进路错落布置更利于形成稳定的硐室群结构。
英文摘要：
Aimed at the complex cavern group formed during underground mining in Yongping Copper mine, two roadway layout models were built by F1AC3D, and the results of plastic zones, displacement and stress after mining were analyzed and com- pared. The research showed that asymmetric arrangement of ore-drawing crosscut and drift was more conducive to forming the stable cavern group structure.
