针对高应力孤岛工作面围岩破碎巷道支护难的问题,以国阳一矿81202回风巷为研究对象,结合其采矿地质条件,分析了孤岛工作面围岩破碎巷道的破坏失稳机理,提出了锚杆与高强锚索联合支护的优化方案,采用FLAC3D软件模拟了优化方案与原支护方案对围岩变形的控制效果。结果表明:采用锚杆与高强锚索联合支护后,81204工作面回风巷在掘进及回采期间,巷道顶底板相对移近量分别减小了23%和63%,两帮移近量分别减少25%和60%。 Aiming at the difficult supporting of surrounding rock mass destruction roadway in high stressed island face, taking the 81202 return airway of Guoyang No.1 mine as the research object, combined with the mining geological conditions, the failure instability mechanism of surrounding rock mass destruction roadway in island work surface is analyzed. The optimization scheme of combined support of rock bolt and high-strength anchor cable is put forward. The FLAC3D software is used to simulate the control effect of the optimization scheme and original support scheme on the deformation of surrounding rock. The results show that the relative displacement of top and bottom roadway in tunnel return airway of 81204 working face decreases by 23% and 63% respectively during the tunneling and excavation with the combination of bolt and high-strength anchor cable, Reduce by 25% and 60%.
