| 中文摘要: |
| 井中磁测离深部场源近,能避开浅部干扰,是一种有效的找矿手段,但其控制范围有限;地面磁测采集方便且控制范围大,但老矿区干扰因素多,深部矿体信号弱,不容易解释。文章充分利用地面和井中磁测资料的优点,以二度板状体模型为例,进行井地磁测资料联合反演。通过数值模拟说明了井地联合反演方法的优越性,同时还比较了马奎特法,广义逆法和遗传算法三种不同算法的优缺点,最后将其应用于大冶铁矿实际资料的处理解释,为危机矿山的深部找矿提供了一种有效的方法。 |

| Borehole magnetic measurement has the advantages,such as magnetometer is close to the magnetic sources and can avoid interference from shallow strata,which is an effective method for ore exploration.However,the control scope of borehole magnetic measurement is limited while the surface magnetic survey is convenient to make data acquisition and has larger recovery.Nevertheless,surface magnetic survey is confronted with problems,for instance much interference to geophysical detection in the old mining areas,w... |
