| 摘 要： | 首先根据围岩强度进行了围岩稳定性分类;提出并实施了以巷道围岩锚注为核心的复合支护方案;实验表明在分别采用聚胺脂、425#水泥进行岩石注浆加固时,岩石强度比其残余强度可以提高0.7-1.1倍、1.3-2.0倍;最后,进行了反底拱支护能力的力学分析。

| Abstract: | The stabilities of surrounding rocks are classified according to their strengths. A united supporting scheme of the grouting bolt is proposed and applied. The experiment shows that the strength of rock grouted by MARITHAN N and 425 cement is enhanced # to 70-110 % and 130-200 % compared with the remain one. The support capability of inverted arch is analyzed . |
