摘要
基于快速掘进施工角度考虑,对现场施工提出了二次锚喷支护技术,现场试验结果表明,该技术可以减少首次锚喷支护作业的工作量,减少迎头支护作业的时间,采用二次支护后,不仅西四轨道平巷掘进速度提高了近30%,也解决了深井巷道的围岩支护难题。
According to rapid excavation, this paper puts forward secondary bolt-shotcrete support to field construction. The resuhs showed that secondary bolt-shotcrete support technology could reduce the workload of first bolt-shotcrete support and the time of driving face support. Secondary bolt-shotcrete support could not only improve 30% of Xisi track driving speed, but also solved the difficult problem of deep roadway.
