深部高应力软岩巷道耦合支护效应研究及应用

Study and Application of Coupling Support Effect in Deep High-stress Soft Rock Roadway

针对深部高应力软岩巷道围岩应力大,围岩变形严重的问题,以铂龙矿80101工作面为工程背景,基于深部软岩巷道变形破坏机理和耦合支护技术,设计了深部软岩巷道卸压支护技术。实践效果良好,有效控制巷道围岩变形,顶板变形量减少205 mm,保证工作的安全开采。

In view of the problem of large stress and serious deformation of surrounding rock in the deep high-stress soft rock roadway,and taking the 80101 working face of Bulong Mine as the engineering background,based on the deformation and failure mechanism of the deep soft rock roadway and the coupling support technology,the pressure relief support technology for the deep soft rock roadway is designed.The practice effect is good,the deformation of surrounding rock in the roadway is effectively controlled,and the deformation of the roof is reduced by 205 mm to ensure the safe mining of the work.
