摘 要: | 由于巷道围岩破碎不稳定,支护的悬吊、组合拱、组合梁等作用不明显,原有的巷道支护方式—锚网喷支护,不能有效的控制围岩和对巷道进行有效的支护,巷道变形严重,通过对巷道围岩进行注浆处理,使巷道围岩相对稳定,从而使原有支护方式对巷道起到有效支护的作用。

Abstract: | Because of roadway surrounding rock crushing is not stability,support of the suspension,the combination of the arch,such as composite effect is not apparent,the original roadway support ways--the anchor net spray support,not effective control of surrounding rock of roadway and effectively support,roadway deformation serious,therefore through the surrounding rock of roadway grouting treatment to keep the roadway surrounding rock relatively stable,so that the original supporting method on the roadway an effective supporting role. |
