| 摘 要： | 对255旧运巷进行"拱桥法"锚注加固支护后,加固区段的锚杆在破碎岩体中具有悬吊机制和组合作用,同时注浆对岩体的充填与粘结的综合作用,使巷道围岩共同形成了一个封闭环拱桥形式的承载结构,从而有力地控制了岩体的移动变形。计算结果表明,对旧巷进行"拱桥法"锚注加固支护后,处于低应力区的旧运巷围岩移动量仅为0.36mm,巷道周围岩体没有新的破坏区产生,充分证明该加固设计方案的合理性和施工手段的有效性。

| Abstract: | After the grouting and bolting of subsiding area of 255 main transport-roadway in linglong gold mine, rock-mass compound a solid system in terms of hybrid effect in order to decrease displacement and damage. The displacement only adds up to 0.36mm in lower stress area and there is no damaged. Those approve that the reinforce project are effective. |
