锚注支护是将锚杆支护和注浆技术有机的结合在一起，共同作用的支护技术，尤其对松软破碎岩体的支护极为有效，使锚杆和注浆的适用范围得到扩展，提高了对软岩的支护效果。锚注支护既加固了围岩，又为锚杆提供了可靠的着力基础，使围岩强度和承载能力得到显著提高，巷道变形量明显降低，在分析锚注支护机理的基础上，分析了锚注支护特点及适用范围，得出巷道锚注支护可改善锚杆、裂隙面及围岩的力学性能，减小围岩塑性区及巷道位移，提高围岩的稳定性的结论。

Bolting-grouting is combined with anchor-supporting and grouting, is an effective measures to support extremely soft seam of coal mine with complex roof. It can enlarge the scope of application of anchor-supporting and grouting and improve supporting effects of soft rock. Not only can bolting-grouting reinforce surrounding rocks but also it can provides a reliable anchor eforts basis. What's more, the surrounding rock strength and carrying capacity could be significantly improved and the amount of roadway deformation could be significantly reduced. Based on the analysis of the mechanism of bolting-grouting, we analyze the characteristic of bolting-grouting and its scope of application. Conclusions can be drawn that bolt-routing supporting can improve mechanic properties of blot, fracture and wallrocks and diminishes wall-rock plastic zone and drift displacement,and increase wallrock stabilly.
