| 摘 要： | 针对规划区瓦斯治理底板岩巷石门在高应力软岩巷道掘进过程中遇到的支护问题,提出采用中空注浆锚杆支护体系对巷道围岩进行控制。现场应用结果表明,该支护方式可以增加围岩自身承载能力,有效控制围岩变形,取得较好应用效果,为矿井高地应力软岩巷道支护提供有益参考。

Application of Hollow Grouting Bolt in Soft Rock Roadway with High Stress |
| |
| Abstract: | In view of the supporting problems encountered in the process of tunneling of soft rock roadway with high stress,the hollow grouting bolt supporting system is proposed to control the surrounding rock of the roadway.The field application results show that the supporting method can increase the bearing capacity of the surrounding rock,effectively control the deformation of the surrounding rock,and achieve good application results,which provides a useful reference for supporting soft rock roadway with high ground stress. |
