摘　　要：通过对传统充填隔离墙的对比,针对矿山需构筑的充填隔离墙宽度、高度较大的特点,提出了采用袋装充填尾砂砌筑隔离墙,并用钢管、圆钢、锚杆等作为主要构架材料的固定成形技术。经现场工业试验,在挡墙宽度、高度20m左右时,通过该方法砌筑的挡墙稳定性好,对空区内的充填料浆起到了很好的限制作用,最终实现了高大采空区的分区隔离,为矿柱的回收创造了良好的条件。According to the large width and height of the partition wall required in mine,a new fixing and forming technology was proposed by comparing with the traditional filling partition wall,with bagged tailings as filling partition wall and steel pipe,steel rod and anchor bolt as the main framework materials.The industrial field tests showed that under the wall width and height of about 20 meters,the stability of the partition wall built by this technology was good enough to limit the filling slurry in the goaf.Finally,the separation and isolation of the high and large goaf was realized,which provided good conditions for pillar recovery.
