摘　　要：大冶铁矿项目属2004年度危机矿山接替资源勘查项目9个试点项目之一。该项目的实施,不但取得了深部找矿的重大突破,解决了接替资源问题,而且也为全国危机矿山深部找矿工作的开展起到了示范作用。以开展的40个钻孔井中磁测的工作资料为基础,分析18个有磁异常钻孔,推断为盲矿异常引起。通过测井工作有效地发现了深部井旁磁源体(矿体)异常,较准确地对矿体(磁源体)进行空间定位预测,为钻探工程布置提供了靶区,取得了较好的深部找矿效果。Daye iron mine project is one of the nine experimental projects for the prospecting of crisis mines in 2004.Through this project,deep concealed ores are exposed and it has become an example for other crisis mines.This paper presents the application of borehole magnetic prospecting conducted in the Daye iron mine.18 anomalies from borehole magnetic prospecting in 40 bores are inferred as deep concealed ores.And the authors predict spatial location and shapes.All these guide the disposals of drillings and obtain good result.The drill hole＇s success according to the explanation result sees this point.
