摘　　要：程潮矿业新选矿厂雨排水隧道施工过程中,隧道出口段发生了垮冒,垮冒的松散体将隧道封堵,增加了后续施工难度。根据具体情况,经分析研究,决定垮冒段采用插杆法施工。方案实施后,顺利通过垮冒段,取得预期效果。During the construction of the rain drainage tunnel in new preparation plant of Chengchao Mining,a collapse was occurred at the exit section of the tunnel,the collapsed loosen mass blocked the tunnel and the late construction difficulty was increased.According the ascertain conditions,after the analysis and study,the construction with the rod insertion method was applied to the collapsed section of the tunnel.After the construction plan was conducted,the collapsed section was successfully passed through and the expected effect was obtained.
