摘要
随着矿井开采深度不断加大,软岩巷道支护问题日益突出。针对某煤矿轨道大巷的变形情况,分析了巷道围岩变形原因,并在原有支护方案的基础上加以总结完善,通过加大巷道支护强度与加强关键部位支护力度,有效控制了围岩变形。
As the depth of mining increases gradually, the supporting for soft rock roadway is more critical. For the deformation of main roadway, the reasons are analyzed and the original supporting scheme is improved. By increasing the supporting strength of the main roadway and other key parts, the surrounding rock deformation is effectively controlled.
