摘要
涡北煤矿南翼一采区轨道上山原支护采用传统的锚网喷支护,支护效果不理想,造成围岩大面积破坏,巷修工作量大,直接影响矿井的正常生产和经济效益,结合现场实际,在原支护基础上采用锚网带喷支护,以满足巷道变形的要求,取得了较好的支护效果。
In Guobei Coal Mine, it was not ideal that the support of the inclined roadway through the first mining area of South Wing employed the original anchor net supporting shotcrete which has caused large area of surrounding rock damage. At the same time, the workload of roadway repair was big, which influenced the normal production and economic benefits directly. So combined with the actual, we adopted anchor net steel belt shotcrete support to fulfill the requirements of the roadway deformation which has achieved good supporting effect.
