摘要
随着我国煤炭事业的快速发展,在软岩巷道中已经广泛使用锚杆锚索联合支护技术。在软弱易碎的巷道中应用高强度锚杆、锚索方法进行支护,能够有效分散顶板隔离层对锚索的压力,防止软岩的变形导致的锚索破坏,使锚杆充分发挥软岩的加固作用,有效地预防锚索断裂所引起的顶板塌陷事故。
The paper introduces the application of high -strength bolting -and-cable anchor supporting technol‐ogy in roadway with soft and broken rock ,which can effectively improve the reinforcement of bolting in soft rock and prevent the roof collapse caused by the broken cable anchor by dispersing the pressure of roof isolated layer on cable anchor and preventing the failure of cable anchor caused by soft rock deformation .
