摘　　要：针对回采巷道在高应力、复杂地质条件下支护效果不佳的问题,文章提出了锚杆锚索联合支护技术优化方案。通过数值模拟与现场试验,优化锚杆与锚索的参数配置,如锚杆长度、锚索直径及预紧力等,以增强支护结构的承载能力和稳定性。研究结果显示,优化后的联合支护方案有效控制了巷道围岩变形,提高了支护效率,降低了维护成本,可为类似工程项目的开展提供参考借鉴。Based on the problem of poor support effect of stoping roadway under high stress and complex geological conditions,this paper puts forward the optimization scheme of bolt and anchor cable combined support technology.Through numerical simulation and field test,the parameter configuration of bolt and anchor cable is optimized,such as bolt length,anchor cable diameter and pre-tensioning force,so as to enhance the bearing capacity and stability of support structures.The results show that the optimized combined support scheme effectively controls the roadway surrounding rock deformation,improves the support efficiency and reduces the maintenance cost,which can provide reference for the development of similar engineering projects.
