摘要
针对中色非洲矿业公司下属谦比西铜矿西矿体围岩的工程地质、水文地质条件及岩体力学特性复杂性,运用岩体工程地质力学方法进行了工程地质岩组划分、节理裂隙统计和岩体结构分类。利用RMR分级及Q系统分级方法对不同岩组的岩体质量进行了分类和评价,得出了工程岩体质量评价结论,为西矿体采矿和巷道支护设计方案提供了基本地质资料。
In light of the complexity of the engineering geology, hydrogeology conditions and the mechanical characteristics of sur- rounding rock of western ore body in Chambishi copper mine which belongs to Africa Mining PLC of China Nonferrous Metals Co. , the di- vision of engineering geology rock groups, the rock fracture statistics and the classification of rock structures were made. The rock quality of different rock groups were classified and evaluated with RMR classification system and Q classification system. The results were ac- quired by two evaluation methods which provide the basic geological information for mining and roadway support designing of western ore body.
