摘要
陈四楼矿-720 m辅助水平回风大巷为典型的深部厚松散层破碎围岩巷道,该巷道在原有支护方案下支护失效。针对辅助水平回风大巷的支护难题,研究分析了其变形机理及破坏特征,在原支护方案的基础上,对支护参数进行优化设计,并利用FLAC3D对巷道支护方案进行模拟对比分析。
The-720 m level auxiliary horizontal alleys roadway is a typical deep thick loose crushed surrounding rock roadway in Chensilou coal mine,the original supporting scheme is failure. In view of the support problem in Chensilou coal-720 m level auxiliary horizontal alleys roadway,focuses on analyzing the characteristics of deformation and failure,compare the simulation analysis for roadway support scheme with FLAC3 D. On the basis of the original support scheme,optimize the supporting parameters.
