| 中文摘要: |
| 根据松软岩层中的大型硐室支护的理论,针对和睦山矿区软岩硐室的具体情况,采用柔性初次支护卸压,适度滞后的强力二次支护的方案,并描述了其支护机理.通过对工程硐室的现场实测结果进行统计,证明方案支护效果显著. |
| 英文摘要: |
| Based on the support and reinforcement technology of large chambers and in view of the situation of the soft Rock chamber in Hemushan Mine,the support technique that the firstly support is flexible to relief the earth pressure and the moderate postponerment of the secondary support is rigid is employed.The mechanism is described.It is proved by the monitoring of Soft Rock Chamber that the applied effects are remarkable. |
