摘　　要：针对深部巷道围岩松散破坏范围大、锚杆支护系统往往出现大面积破断及整体外移问题,以均衡巷道全断面受力、锚杆支护系统与围岩间的耦合协调让压为原则,确定了具体参数,充分发挥了系统主动支护作用。研究成果对深部巷道支护具有一定的指导和借鉴意义。Aiming at deep large range of loose surrounding rock, bolt support system tend to be large breakage and the problem of off shoring as a whole, to balance the whole section stress of roadway, and bolt support system with coupling coordination let pressure equalization of surrounding rock for the principle, determine the specific parameters, give full play to the system active supporting resistance. Research results have certain guidance and reference significance for deep roadway support.
