摘要
在对新集三矿原软岩巷道支护及修复方案存在问题的基础上,提出了巷道排水疏干后适时采用U型棚+围岩注浆加固的巷道修复支护方案,工程应用实践表明:采用该支护方案后围岩变形较小(稳定),达到了预期的目的。
Basis on the problems exsiting in the supporting and renovating plan of original soft rock tunnel of NO. 3 mine in xinji, this article proposes a. sopporting and renovating plan by adopting steel in form of U--shape and injecting serosity into the surronding wall to reinfore at the rignt moment af- ter draining and drying off the water. Applied project practice indicate that the surrouding wall is less deformed after applying this plan and expectant purpose is reached
