摘要
某铜钼矿北矿段西帮为运矿廊道,上部边坡并段后受断层影响,存在重大安全隐患。为了确保该区域边坡稳定,探讨了该矿高寒气候及地质赋存条件对边坡稳定性的影响,提出了锚杆+锚索+框架梁联合支护边坡加固方案,并对该支护方案进行了FLAC^(3D)数值模拟分析。结果表明:在采用此加固方案情况下,加强地下水导水、控制爆破震动可实现北矿段西帮边坡稳定。
The west side of northern ore section of studied copper⁃molybdenum mine is the ore transport corridor,and there are some great potential safety hazards existing in the upside slope with the impact of fault after the merged sub⁃level mining.In order to guarantee the slope stability of this area,the paper discussed the influences of climate as well as geological occurrence conditions in this mine on slope stability,put forward the combined supporting slope reinforcement scheme with anchor stock,anchor rope,and framed girder,and carried out the FLAC^(3D) numerical simulation analysis for this scheme.The results indicated that this supporting scheme could strengthen the underground water diversion and control blasting vibration,in favor of the stability of the west slope of the North mine section.
