摘　　要：在某磁铁矿勘查过程中,为了对矿层产生的磁异常进行计算并开展深部磁性盲矿层进行预测,在工作区开展了勘探线剖面图收集、钻孔对比、勘探线精测剖面、钻孔岩心磁参数测试计算,并进行2.5D人机交互反演工作。如果有较大的剩余异常,则在深部有盲矿层的可能性大,反之,则无。In the processing of a magnetite prospecting, we have made a prediction in deep magnetic blind ore for the calculation of residual magnetic anomaly. This paper conducts prospecting line profile map collection, including borehole contrast, prospecting line precision measurement profile, drill core magnetic parameters tests and calculates, as is a development to 2. 5D interactive inversion. If it has a larger residual anomaly, it will be of a big possibility of blind ore.
