摘　　要：光爆锚喷支护在岩层破碎巷道中的应用取得了理想的效果。相对于钢棚支护,这种支护方式更能保持巷道围岩的完整性和稳定性,并能适应围岩的变形,有利于二次维护。另外采用光爆锚喷支护能降低工人的劳动强度,提高单进水平,进而增加经济效益。Smooth blasting and combined support with shotcrete and bolting were applied in the broken rock roadway. The ideal result was obtained. As opposed to steel shelf support, this sup- port maintains the integrity and stability of surrounding rocks, and adapts to the deformation of rocks, it is conducive for the second maintenance. In addition, using smooth blasting and combined support with shotcrete and bolting can reduce the labor intensity, improve the single footage level and increase the ecomomic efficiecy.
