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。

In view of the large range of loose rock mass destruction in deep roadway, the bolting system often has the problem of large area breakage and overall migration, so as to balance the stress in the whole section of roadway, and the principle of coupling and coordination between bolt support system and surrounding rock , Determine the specific parameters, give full play to the role of active support system. The research results have some guidance and reference significance to the deep roadway support.
