摘要
针对某矿10110运输顺槽面临的顶板破碎、顶板淋水等支护困难,分析了传统工字钢架棚支护在实践应用中的缺陷,设计采用新型防水锚固剂、高强度锚杆、金属网、钢筋梯子梁、小孔径预应力锚索的新型支护方案,取得了良好的围岩控制效果。
Aiming at the difficulties of roof breakage and roof watering in 10110 conveyance chute of a mine,this paper analyses the defects of traditional I-steel roof frame in practical application,designs a new support scheme with new waterproof anchorage agent,high strength anchor,metal mesh,steel ladder beam,anchor-cable of small aperture prestressing.And good control effect of surrounding rock has been achieved.
