摘　　要：针对矿山开采过程中岩体结构面信息的获取,利用先进的ShapeMetrix 3D系统实现岩体结构面信息的准确、快速、大量获取。选择红岭铅锌矿755 m、705 m和666 m中段开拓巷道中60个测点的岩体结构面进行摄像测量,对测量结果进行分组与分析,得到各测点的结构面外观质量与几何参数信息,通过数理统计分析,得到各结构面几何参数的概率分布模型。结果表明,红岭铅锌矿矿岩节理状态中等,部分扫描点位置状态较差。其中,666 m中段整体节理状态表现最好,755 m中段次之,705 m中段最差。最终归纳分析确定红岭铅锌矿深部岩体结构面优势产状主要有两组,分别为279.44°∠51.09°和97.73°∠50.23°。In view of the acquisition of rock mass structures information in the mining process,the advanced ShapeMetrix 3D system is used to achieve accurate,rapid and massive acquisition of rock mass structures information.The rock mass structures of 60 measuring points in the 755 m,705 m and 666 m development roadways of Hongling Lead-Zinc Mine were selected for camera measurement.The measurement results were grouped and analyzed to obtain the appearance quality and geometric parameter information of structures of each measuring point.The probability distribution model of geometric parameters of each structure was obtained through mathematical statistics analysis.The results show that the joint state of Hongling Lead-Zinc Mine is medium,and the position state of some scanning points is poor.Among them,the overall joint state of 666 m is the best,followed by 755 m,and 705 m is the worst.Finally,it is concluded and analyzed that there are mainly two groups of dominant occurrence of structures of deep rock mass in Hongling Lead-Zinc Mine,which are 279.44°∠51.09°and 97.73°∠50.23°,respectively.
