| 摘 要： | 古汉山矿东翼通风疏水大巷先后采用了多种支护方式均未取得成功．为了满足掘进巷道的技术要求，解决巷道的变形，通过对巷道支护与围岩相互作用及目前各类巷道支护形式及支护效果分析研究，决定采用锚注支护方案．其实质是采用注浆锚杆兼作注浆管使用，一方面通过注浆改变围岩的物理力学性能，另一方面又为锚杆提供了可靠的着力基础，提高了锚杆的支护效果．断面内注浆锚杆自下而上先注底脚，再注两帮，最后注拱顶锚杆、掘进巷道500m，通过现场施工及施工后的监测，巷道能满足设计要求，取得了较好的支护效果．

| Abstract: | A lot of supporting methods were adopted in the east ventilating and draining entry of Guhanshan Coal Mine, but none of them is succeeded. In order to meet technical needs and minimize the deformation of tunnel, bolt-grouting supporting program was adopted on analysis of interaction between supporting and wall rock. Its essential is that bolt is used as grouting tube. Not only properties of physical and mechanics of rock were changed but also reliable adhesive basis for bolt provided by grouting. Grouting and bolting were conducted from bottom to top of the entry. Five hunderd meters were tunneled successfully and better effects were proved. |
