摘　　要：介绍了高阶段深孔空场嗣后充填采矿方法在李楼铁矿的应用,同时开展井下大型采场开采过程中稳定性研究,确定采场结构尺寸宽、高不变,将矿房或矿柱分2～3部分进行回采,达到预期效果,取得良好的经济效益.The application of the long hole open stope filling later method of high phase in the Lilou iron ore is introdueted. At the same time , the stability of mining process of the large underground stope is researched at length. Accroding to the research findings, the width and height of the stope structure are unchanged. The ore room or pillar is divided into 2 -3 sections, and they are recoveried respectively so as to achieve the desired effect and obtain good economic benefits.
