摘要
以晋华宫矿2105巷为研究背景,利用FLAC3D模拟了软弱层对顶板稳定性的影响,采用钻孔摄像实测了顶板松动圈厚度,基于松动圈支护理论设计了复合顶板稳定控制方案。现场应用结果表明,复合顶板支护效果良好。
2105 roadway of Jinhuagong mine is taken as a research subject, the impact of the weak layer on roof stability is studied by FLAC3D, the relaxation zone of the roof is measured by the borehole camera technology, and the composite roof stability control program is designed on the base of the loose circle support theory. The results of application show that the combined roof supported is good.
