摘　　要：切眼在顶板破碎区掘进时,若顶板破碎区范围较大会存在较大的支护难度,在对和瑞煤业松软煤层中顶底板岩性分析研究的基础上,决定采用锚网梁索联合支护技术,并用FLAC3D软件进行了模拟分析。结果显示,采用锚网梁索联合支护后,巷道围岩变形量大幅减少,特别是切眼顶板下沉量降幅明显,具有良好的实际应用效果。When the cuttings are dug in the fractured area of the roof slab, there is a large support difficulty if the fractured area of the roof slab is large. After analyzing and researching the lithology of the roof and bottom slab in the loose coal seam of He Rui Coal Industry, it was decided to adopt the joint support technology of anchor network beam and rope, and the simulation analysis was carried out with FLAC3d software. The results show that the deformation of the roadway surrounding rock is significantly reduced after adopting the combined anchor network beam and rope support, especially the reduction of the sinking of the roof slab of the cuttings is obvious, which has a good practical use effect.
