摘　　要：针对留巷巷道围岩变形破坏难题,采用理论分析、数值模拟及现场实测等相结合的研究方法,揭示了留巷巷道围岩变形破坏特征和机理,提出了留巷巷道注浆加固方案。对注浆加固方案进行了现场试验,试验结果表明,采用注浆加固和强力锚杆锚索支护后巷道围岩完整性较好,巷道变形完全控制在要求范围内,达到了支护效果。Aiming at the problem of deformation and failure of surrounding rock of retained roadway, the characteristics and the mechanisms of deformation and failure of surrounding rock of retained roadway were revealed by combining theoretical analysis, numerical simulation and field measurement. The supporting scheme of retained roadway was put forward and field test was carried out. The test results showed that the surrounding rock integrity of the roadway was good after grouting reinforcement and strong bolt and cable support, and the deformation of the roadway was completely controlled within the required range, which achieved the support effect.
