| 摘 要： | 锚注支护就是针对节理、裂隙发育,断层破碎带等围岩松散、破碎情况,利用锚杆注浆技术,改变围岩结构,提高其粘结力、内摩擦角和围岩整体性,使巷道支护能充分发挥作用的一种支护方法,通过实践切实解决了巷道掘进过程中的顶板破碎问题,使矿井的掘进支护更趋于合理。通过对其技术的具体总结阐述,使在以后的应用中能够更加广泛,为巷道采用新型的锚杆支护技术做好铺垫。

Application of Bolt Grouting Support in Driving Strata Breaking Zone |
| |
| Abstract: | Bolt grouting support is aimed at soft and breaking surrounding rock of jiont cracked and fault breaking zone,bolt grouting technology was utilized,cohesion,internal-friction and surrounding rock ectirety were improved,it is a good supporting methods for roadway support,through practice,roof breaking problem was solved,driving support of mine becomes rationalization.Through summarizing,new bolt support technology make good foreshadowing for now on. |
