| 摘 要： | 某钨矿+496m水平运输巷道7线与11线之间被F2大断层切割,岩体破碎,同时竖井掘进出来的废石被直接堆放至+496m水平运输巷道地表,加剧了+496m水平运输巷道F2断层破碎带附近区域的岩层移动。用FLAC~(3D)数值软件进行了巷道开挖后的模拟,模拟了巷道上覆岩土动态加载对巷道围岩变形的影响情况。根据不同的地质特征,为数值模拟提供实效的参数,确保数值模拟的准确性,为支护模拟提供数据依据。

| Abstract: | In one tungsten mine, the No.7 to No.11 line in haulage roadway on +496 m level are cut by F2 fault, and rock mass is broken. At the same time, the waste rocks are stored directly to + 496 m horizontal haulage roadway surface, these factors result in the rock strata movement. So the FLAC3D numerical software is applied to numerical simulation of tunnel after excavation, the overlying rock of roadway can be analyzed and simulated the dynamic load impact on the wall rock deformation of roadway. According to different geological features, the parameters of the actual effect is provided to simulate process, ensure the accuracy of the numerical simulation and provide data basis for supporting simulation. |
