摘　　要：周源山矿采深大、压力大,原有的梁式支护已越来越不适应现有的生产地质条件,为此,在现场锚杆锚固力拉拔试验的基础上,应用现代锚杆支护理论进行了24回风上山锚杆支护参数设计,并对24回风上山采用预应力锚杆+锚索支护的围岩松动圈厚度进行了数值模拟,试验和模拟结果表明:锚梁网索支护在深井煤巷支护中是一种极其有效的支护形式,值得在全矿推广应用.Because of large mining depth and great pressure, beam supporting in Zhouyuanshan Mine has been not satisfying the existing condition of geology and production. Therefore, bolt support parameters of 24 return airflow uphill are designed by using the modern of bolting support based on pull - thickness of surrounding rock loose circle has been simulated for prestressed Both experiments and numerical simulation show that wire meshes beam out test for bolt anchoring force, and the anchor bar （cable） supporting roadways. and cable anchor support is an effective supporting form, which is worthy of popularization and application in the whole mine.
