摘要
东大洼铁矿位于大庙—黑山一带铁矿成矿带上,区内地表浅部矿体分布范围已基本确定。为了在2000m以下寻找具有一定规模的深部铁矿体,利用高精度磁法面积性测量圈定了区内矿体的分布范围;通过磁法精测剖面的2.5D人机交互反演,推断深部仍有隐伏铁矿体存在,为东大洼铁矿区寻找深部第二找矿空间提交新增矿石储量提供了可靠的地球物理依据。
Dongdawa iron ore deposit is located in the iron ore belt in the area of domiao-heishan,The distribution range of shallow iron ore bodies in the area has been basically determined. In order to f ind a certain scale of deep iron ore body below 2000 m , The distribution range of ore bodies in the area is determined by using the high-precision magnetic method, By using the 2.5-d human-computer interactive inversion of the magnetic precision prof ile, it is concluded that there are still hidden iron ore bodies in the deep part.,It provides a reliable geophysical basis for the new ore quantity submitted in the second deep prospecting space.
