- Discussion on countermeasure of ecological protection for tunnel entrance construction and blasting technique for weak surrounding rock 生态保护进洞对策与软弱围岩爆破技术的探讨
- weak surrounding rock 软弱围岩
- If the surrounding rock is soft and is later worn away, the walls remain and form ridges called dikes. 如果围岩柔软,日后又被剥蚀掉,这种岩壁就下来形成山脊,称为岩墙。
- It is possible to use Gurit without damaging the surrounding rock. 使用古力特炸药将完全可能不造成对围岩的破坏。
- It is found that the main problems are the uncoupled strength and the uncoupled regidity between the support and the surrounding rock in the soft rock. 文中认为目前煤矿软岩巷道支护存在的主要问题是支护体与围岩之间的强度或刚度的不耦合问题。
- It was shown that there was alternation of strong and weak strength-softening region in the surrounding rock of deep roadways. 研究结果表明：深部巷道围岩中存在围岩强度强、弱软化区域交替出现的现象；
- The surrounding rock of 9300 drift is of plastic soft type. Because of great ground pressure, rock movement and long action duration, the support facilities were destroyed. 9300平巷由于围岩为塑性软岩体,地压、位移大,且持续时间长,因而巷道支架破坏严重。
- Based on the measured results and field survey, the cause of the failure and deformation of the surrounding rock around soft rock laneway in MaLuPing mine are discussed. 根据现场调查和实测结果,分析了马路坪矿软岩巷道围岩变形和破坏的主要原因。
