摘　　要：巷道的塌陷破坏是矿山中常见问题之一,不同的地质情况下,采用的治理方法也各不相同。本文分析了玲珑金矿255巷道塌陷机理,采用“拱桥法”注浆加固技术,通过合理选择注浆压力等工艺参数、对注浆加固过程进行优化控制,使玲珑金矿255新、旧巷道治理后已经恢复生产。实践证明,拱桥法注浆加固技术是一种行之有效的巷道加固方法。Tunnel collapse is one of the common phenomena in mine production. The maintenance and repair method is varied with its geological conditions. Based on the research on the collapse mechanics of 255 tunnel in Linglong Gold Mine,the paper proposed a method named“arch bridge method”grouting reinforcement. The new and old 255 tunnel of Linglong Gold Mine have normally come into its operation again after they were maintained by selecting reasonable technological parameters like grouting pressure etc. Practice proves“arch bridge method”is a very effective reinforcement method.
