摘　　要：为了解决深部倾斜岩层巷道围岩大变形难控制问题,以九龙矿15240运输巷为工程背景,通过现场调研、原位测试和数值模拟,总结了原支护下巷道围岩变形破坏特点,获得了围岩裂隙主要分布范围,结合强帮支护理论和管索组合结构(简称ACC)支护技术,提出采用“顶帮全ACC+复合网+W型钢带”的联合支护方案,并在现场进行应用。结果表明:巷道破坏表现为顶板下沉严重、两帮及肩角非对称变形明显和支护构件大量损坏;围岩裂隙主要分布在距巷道表面1.8 m范围内;与原支护方案相比,优化支护方案应用后,巷道顶板下沉量和帮部近移量分别比原支护方案减少了45.88%和27.92%,巷道非对称大变形得到明显控制,锚索剪切失效现象未再发生,巷道整体稳定性得到提升,优化支护方案取得了良好的支护效果。研究结果可为类似地质条件下巷道支护技术提供参考。In order to solve the problem of difficult control of large deformation of roadway surrounding rock in deep inclined strata,this paper takes transport lane 15240 of Jiulong Mine as the engineering background.Through field investigation,in-situ testing and numerical simulation,this study summarizes the deformation and failure characteristics of roadway surrounding rock under the original supporting conditions.The main distribution range of surrounding rock cracks is identified,and a combined support scheme of“all-top ACC+composite net+W-shaped steel belt”is proposed based on strong wall support theory and Anchor cable with C-shaped tube(ACC)technology.This optimized support scheme has been successfully applied in the field,resulting in a significant reduction in roof subsidence and nearness of the side compared to the original support scheme.Furthermore,it effectively controls asymmetric deformation and prevents shear failure of anchor cables.Overall stability of the roadway has been improved,demonstrating that the optimized supporting scheme has achieved positive results.The findings from this study can serve as a reference for roadway support technology under similar geological conditions.
