| 中文摘要:根据深部软岩条件下煤矿巷道锚杆支护效果不理想的情况，分析认为调整锚杆预紧力的大小是改善支护效果的有效方法。通过在具体支护中对螺纹钢锚杆、淮北预紧力锚杆、高预紧力锚杆进行对比试验，采用高预紧力锚杆支护有效地控制住了深部巷道围岩的变形，同时具有较好的经济效益。 |

| Abstract:The shoring results for coal mine under the soft rock conditions were not perfect. The author thought that adjustment of pre-stress in a efficient method to improve shoring results. Test was made on worm steel anchor, Huaibei pre-stressed anchor and high pre-stress anchor, to compare the shoring results. The high pre-stress anchor shown that it can efficiently control the surrounding rock deformation in tunnel under deep earth. Meanwhile it has good economic benefits. |
