锚网索联合技术在大变形软岩顶底板煤巷支护工作中的应用

Application of Bolt-mesh-anchor Joint Technology in Large Deformation Soft Rock Floor Roadway Support Work

锚杆支护所产生的挟持作用使浅部围岩形成拱形支护体,提高围岩整体的刚度和自身承载力。底角锚杆有效的控制了底鼓变形,锚索提高了岩层稳定性,钢带和金属网有效的阻止了浅部围岩朝深处发展。锚网索联合技术有效的提高了煤巷的安全支护工作。

The hostage role of bolting support made the shallow rock form the arch support body, improved the overall stiffness and self carrying capacity of the surrounding rock. Corner bolt effectively control the kick drum deformation, the rock anchor improved the stability of rock, and the strip and metal mesh effectively prevented the development of shallow rock toward the deep rock. Bolt-mesh-anchor joint technology effectively improved the safe support work of coal roadway.
