摘要
介绍了3D井地磁测联合反演技术及其必要性,并将其应用于大冶铁矿某矿区,获得了较好的效果。该方法适用于我国的各个矿区,充分利用了井中及地面磁测资料的优势、先验信息及解释人员的经验,克服了单一资料反演的缺陷,能够准确地判断地下地质(矿)体的空间形态、位置。
There are certain limitations inversing with surface or borehole magnetic data alone,which lead to multiplicity for the inverse results.Nowadays,the surface-borehole joint inversion is seldom studied at home and abroad.Through demonstrating the principle and necessity of 3D joint inversion,and the application in Daye iron mine,we proved the favorable effect in mineral exploration.This method,which takes full advantage of the surface,borehole magnetic data as well as the experience of interpretation workers is applicable to all mines in China.At the same time,the method overcomes the disadvantages of inversing by surface or borehole magnetic data alone,and can determine the spatial shape and location of the geological bodies accurately.The latter results verify the effectiveness of the method.
