摘　　要：针对吴集铁矿矿床被约140m厚第四系岩石覆盖,采矿过程中地表不允许塌落,合理选择了阶段空场嗣后充填法采矿,开展了低品位铁矿高浓度全尾砂结构流胶结充填实验研究并成功应用,取得良好的经济和社会效益。Wuji Iron Ore mine is covered fully by rocks of quaternary system, and the subsidence of earth surface during mining operation is not permitted. Therefore, the technology of stowing （filling） after open stope mining is selected. As consolidated fill material, the high-density tailings from beneficiation process of low- grade iron ore are tested with satisfactory result. The successful application of such tailings has achieved good economic and social benefits.
