摘要: 介绍了玲珑金矿255 m 水平主运输巷道塌陷破坏的成因、加固治理的难点和拱桥法锚注加固技术的要点与实施方案,对该技术的加固力学机制和加固效果进行了系统分析Abstract: Collapsing of main transport opening made the Linglong Gold Mine facing production stop and serious safety trouble. Because the rock surrounding the collapsed opening is extremely broken and loose, reinforcing of the opening is very difficult. This paper introduces a technique which combines the advantages of high pressure grouting and long rock bolting, and uses the principle of arch and bridge to make the collapsed opening stabilized. Reinforcing mechanism and effect of the technique are analyzed.
