深部矿井软岩巷道围岩稳定性控制问题一直是困扰矿井安全生产中的难题。以老君堂矿轨道下山的实际情况为研究对象,采用FLAC~(3D)数值模拟软件,分别对不同治理方案下的巷道垂直位移、塑性区的情况进行对比分析,最终选择了锚网索喷+U形钢+全断面注浆的治理方案。
The control of surrounding rock stability in deep mine soft rock roadway has always been a difficult problem in mine safety production. Based on the actual situation of the downhill orbit of Laojuntang mine, FLAC 3D numerical simulation software was used to analyze the vertical displacements and plastic zones of the roadway under different control schemes respectively. Finally, + U-shaped steel + full-face grouting governance program.
