摘　　要：根据现场3117综采工作面机巷的实际情况,提出了采用现浇混凝土墙作为巷旁充填支护技术,确定了现浇混凝土墙作为巷旁充填支护的技术参数。采用现浇混凝土墙作为巷旁充填支护技术效果较好,沿空留巷顶板变形量较小,从而有利于煤层的安全高效回采。Departures from the practice of the machine roadway of the No. 3117 working-face, then the support technology beside roadway use reinforced concrete wall was introduced, and the parameters of this technology is established. The effect is obvious about the support technology beside roadway use reinforced concrete wall, the roadway roof deformation is small, which is benefit to the safe and high- efficient mining of the coal seam.
