| 摘 要： | 针对深部巷道支护难、围岩变形量大等问题，采用TATW-2000岩石三轴试验机对研究区煤岩物理力学性质进行测试，得到了煤岩物理力学参数，然后采用FLAC3D数值模拟软件，分析了现有支护状态下巷道围岩的变形规律和巷道竖向、水平位移分布。研究为后期巷道支护参数的优化提供了理论基础。

| Abstract: | In view of problems of difficult supporting and large deformation of surrounding rock in deep roadway,the physical and mechanical properties of coal rock in the study area were tested by using TATW-2000 rock triaxial testing machine,and the physical and mechanical parameters of coal rock were obtained.Then,the variation law of surrounding rock and the vertical and horizontal displacement distribution of roadway under the existing support state were analyzed by using FLAC^3D numerical simulation software.The research provided a theoretical basis for optimization of later roadway supporting parameters. |
