| 摘 要： | 利用井中磁异常矢量分布特征能确定引起该异常磁源的走向.其作用不仅可以判断磁性体相对于钻孔的位置,而且可以进行定量和半定量计算,以及经旋转一角度采用地面方法作反演解释,计算矿体头部或尾部距已知钻孔的距离、深度,设计下一钻孔的深度、顶角、方位角.这种方法简便易行,应用在大冶铁矿的矿山深部找矿效果很好.

| Abstract: | Vector characteristics of magnetic anomaly measured in drill holes can be used to determine the strike of magnetic source that results in the magnetic anomaly.It can be used not only to infer position of the magnetic body relative to the drill hole but also to make quantitative-semi-quantitative calculation and inverse interpretation and calculation of the distance and depth from head or tail of ore bodies to the known drill hole at surface by rotating an angle so as to design drilling depth,dip angle and orientation of the next drill hole.It is simple and easy and has been applied to iron ore exploration at depth of Daye iron mine with good results. |
