摘　　要：下告铁矿一直采用分段空场法进行回采,矿房回采不规范,使得矿石回收率较低,矿柱矿量和上、下盘残矿矿量较多。为了提高矿石回收率,满足矿山生产要求,分析了其地质概况和开采现状,确定采用3个区段3步骤回采方案进行矿柱的回收,取得了较好的应用效果。The open stope mining method is adopted in Xiagao iron mine, due to the mmmg memou of chambier is not standard, the ore recovery rate is very low and the residual amount of pillars and hang- ing wall and footwall are large. In order to enhance the ore recovery rate, meet the requirement of mine production, the geological situation and mining status of mining area are analyzed, besides that, the three sections and three steps stoping scheme is determined to recycling the pillars and good application effects are obtained.
