摘要
基于煤层开采深度的增大,井下巷道和工作面上覆岩层的水土压力和采动压力逐渐增大,巷道围岩趋向于破坏失稳,巷道所处位置复杂的水文地质条件对巷道的支护措施提出更高的要求,利用耦合支护技术提高深部巷道开采过程中巷道围岩的承载能力,改善围岩的应力条件。经实践证明,耦合支护技术可以明显提高巷道安全性,具有一定实用意义。
Based on the increase of coal seam mining depth,the water and soil pressure and mining pressure on the overlying rock layer of underground roadway and working surface gradually increase,and the surrounding rock of the roadway tends to be destabilized,and the complex hydrogeological conditions of the location of the roadway put forward higher requirements for the support measures of the roadway.The use of coupling support technology can greatly improve the bearing capacity of the roadway surrounding rock in the process of deep roadway mining,and improve the stress conditions of the surrounding rock.
