软岩巷道支护技术是巷道支护过程中遇到的难题之一,巷道开挖引起应力重新分布、巷道变形,特别是在“三软”(顶板软、底板软、煤层软)条件下巷道变形尤为严重,仅靠锚网支护很难达到预期效果。通过对软岩条件下新奥法施工工艺研究,实践证明在清水营煤矿+965m水平车场使用新奥法施工技术,有效地降低了巷道维修成本,增加了巷道施工的安全性。
Soft rock roadway support technology is one of the problems encountered in the roadway support process, roadway excavation caused by stress redistribution, roadway deformation, especially in the “three soft” (roof soft, floor soft, soft seam) conditions Under the deformation of the roadway is particularly serious, it is difficult to achieve the desired effect alone anchor network support. Through the research on the construction technology of New Austrian Method under soft rock conditions, practice has proved that using the new Austrian construction technology in Qingshuiying Coal Mine + 965m level yard effectively reduces the cost of roadway maintenance and increases the safety of roadway construction.
