摘　　要：针对浙江平水铜矿―445 m中段上、下盘围岩和矿体进行了工程地质和物理力学参数分析研究,采用RQD指标基本分类法、南非Bieniawski的地质力学RMR分级法和挪威BaRton的Q系统3种方法对岩体进行了分级,结合矿山实际采用Roclab软件对矿岩的力学参数进行计算分析,得出了各岩体的工程稳定性状况,奠定了井下岩体力学及工程稳定性分析的理论基础。The engineering geology of surrounding rocks and ore bodies at -- 445 m level in Pingshui copper mine was an- alyzed and studied, as well as the physical and mechanical parameters. Rock mass was classified by 3 methods, inclu- ding RQD index classification method, geology mechanical RMR classification method and Q system classification method. Combining with the mine conditions, the mechani- cal parameters of ore and rock were calculated and analyzed by Roclab software. And the stability states of different rock mass were obtained, which provided a theoretical basis for rock mass mechanics and stability analysis.
