高水材料充填支柱在大采高工作面过空巷中的应

为有效解决大采高工作面过空巷期间出现顶板下沉严重、片帮、冒顶、压架、倒架等生产中遇到的难题，确保工作面回采期间安全通过空巷区域，针对成庄矿5314大采高工作面空巷长度长、断面大、且平行于工作面布置等诸多问题，采用理论分析与现场工业性试验相结合的方法，对空巷围岩控制问题进行研究，提出高水材料充填支柱过空巷工艺，并进行现场应用。结果表明：采用高水材料充填支柱对空巷区域进行加强支护，能够有效控制空巷区域围岩有害变形，保障工作面安全、高效、快速通过空巷区域，与木垛、单体液压支柱支护空巷、二次搬家相比，高水材料充填支柱具有显著的经济效益。

Application of High Water Material Filling Pillar in Overpass Alley of Large Mining High Working Face

In order to effectively solve the difficulties encountered in the production of roof sinking, plate helping, roof climbing, pressure frame, and inverted frame during the over-empty lane of the large mining high working face, and ensure the safe passage through the empty lane area during the mining of the working face. In view of the problems of long length, large section and parallel layout of the working face of the 5314 large mining high face of Chengzhuang Mine, the control of surrounding rock in the air lane is studied by combining theoretical analysis with field industrial tests. The process of filling overpass lanes with high water materials is proposed and applied in the field. The results show that the use of high water materials to strengthen the support for the empty lane area can effectively control the harmful deformation of the surrounding rocks in the empty lane area, ensure the safe, efficient and rapid passage of the working face through the empty lane area, and compared with the Muduo and the single hydraulic support. High water materials filling support has significant economic benefits.
