| 摘 要： | 浅部传统支护强度难以满足深部巷道高应力要求。本文分析了薛村矿三水平变电所深部软岩巷道围岩变形破坏特征及影响因素,运用FLAC3D软件模拟了传统锚网索支护与锚网索喷+注浆加固支护两种支护方式。巷道围岩收敛变形监测表明,运用锚网索喷与注浆加固相结合的支护方式能够有效控制深部软岩巷道围岩收敛变形。

Study on Supporting Technology of Deep High Stress Soft Rock Roadway |
| |
| Abstract: | The traditional support system can't adapt to high stress of deep roadways.This paper analyses the damage characteristics and influencing factors of the surrounding rock deformation in three-level substation,Xuecun Colliery,and simulates two kinds of support such as traditional bolt-mesh-cable support and cable anchor+grouting reinforcement support by using FLAC3D software. Monitoring shows that support combined cable anchor with grouting reinforcement can effectively control surrounding deformation in deep soft rock roadway. |
