摘　　要：针对某矿现场对锚杆-锚索协同支护原理认识不足,支护设计存在盲目性问题,基于锚固力学特征,确定优化了深部巷道顶板锚杆、锚索锚固参数,进行现场试验,同时为验证围岩控制效果,对顶、底板及两帮移近量,锚杆-锚索受力情况进行现场监测。采用锚杆-锚索协调锚固技术后,锚杆-锚索协同支护作用得到充分发挥,巷道完整性大大提高,围岩变形量得到有效控制。Based on the roadway in a mine on the scene to the principle of anchor rod, anchor cable bolting together understanding insufficiency,blindness problems in supporting design, based on the anchor mechanics characteristics, anchor cable coordinate anchoring mechanism, determine the optimization of the deep roadway roof bolt, anchor cable anchorage parameters for field test,to verify the control effect of surrounding rock at the same time ,the quantity of roof and floor and two nearer, anchor, anchor cable force for on-site monitoring. The coordination of anchoring bolts-cables technology, anchor rod, anchor cable collaborative supporting role into full play,integrity of roadway is greatly increased, effectively control the deformation of surrounding rock.
