| Abstract: |
| 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. |
