摘要
井下巷道掘进后顶板空顶面积大,在无超前支护作用下补打顶板支护时顶板出现冒落破碎的现象,威胁着支护安全。对此,通过技术研究,设计了一套可移动式超前临时支护装置。经实际应用,153208巷采用该装置后能有效地控制顶板破碎现象,取得了显著的成效。
The roof of underground roadway has a large vacant roof area and the roof collapses and breaks unsteadily when the roof support is supplemented without advance support,which threatens the safety of support.A movable temporary advance support device has been designed through technical research.Through practical application,the roof breakage can be effectively controlled in 153208 roadway by using this device,and remarkable results have been achieved.
