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.
