摘　　要：深部软岩巷道具有非线性大变形特征,单一的支护方式难以控制。锚网喷注支护是具有锚网喷支护与注浆加固共同作用的一种耦合主动支护方式,可以改变围岩力学参数,提高围岩强度。文章结合鹤岗矿业集团兴安矿四水平中央石门返修的工程实践,分析了锚网喷注支护的工程特点。经理论分析和工程应用表明,锚网喷注支护显著提高了围岩的强度和承载能力,有效地控制了深部软岩巷道变形问题,是一种有效控制深部软岩巷道变形的支护形式。As nonlinear large deformation occurs in deep soft rock roadway,single supporting mode can hardly work.Bolt and grouting coupling support is an active method to combine bolt support with grouting reinforcement,which can alter mechanical parameters of surrounding rocks so as to enhance strength of surrounding rocks.Based on engineering practices located at the central stone-door in Xing＇an Coal Mine,this paper analyzes the characteristics of bolt and grouting support.According to the academic analysis and practical application,the bolt and grouting support can considerably improve the capacity and strength of surrounding rocks,which is an effective way to control the deformation in deep soft rock roadway.
