摘　　要：以山西方山金晖凯川煤业有限公司5110工作面内错尾巷为研究背景,对锚杆锚索配合金属网的内错尾巷加强支护技术进行了探讨。通过该技术的应用,巷道顶板位移量小于300 mm,两帮移近量小于86 mm,有效控制了巷道围岩的变形,保证了巷道的正常通风,减少了巷道维护的费用,减少了冒顶片帮事故的发生,提高了煤炭的回采效率。Taking the inner staggered tailway in 5110 working face of Fangshan Jinhui Kaichuan Coal Industry Co.,Ltd.of Shanxi as the research background,this paper discussed the strengthening support technology of bolts and cables combined with metal mesh for the inner staggered tailway.Through the application of this technology,the roof displacement of the roadway was less than 300 mm,and the approach distance of the two sides was less than 86 mm,which effectively controlled the deformation of the surrounding rock of the roadway,ensured the normal ventilation of the roadway,reduced the cost of roadway maintenance,reduced the occurrence of roof falling and slab accidents,and improved the efficiency of coal mining.
