摘要:深部软岩巷道具有较大变形特征,单一的支护方式难以控制。锚网喷支护与注浆加固围岩是一种共同作用的耦合主动支护方式,可以改变围岩力学参数,提高围岩强度。该文阐述在深部软岩中施工大断面煤仓时,应用锚网喷与注浆支护技术的原理、工艺及优点、可操作性以及取得的较好的经济效益,从而促进锚网喷与注浆联合支护工艺的推广、应用。%This paper illustrates the theory, methods, advantage, availability and better economical benefit are got by bolt - net - concreteshoting combined with cement slurry injection being used for coal silo construction in deep soft stratum, and resulting in promoting the methods of bolt - net - concreteshoting combined with cement slurry injection to be used widely.
