| 文章以湖北大冶铁矿、山东金岭铁矿、河北迁安铁矿和新疆蒙库铁矿等矿区的典型钻孔为例,对井中磁测在发现井旁盲矿并确定其空间位置、预报井底盲矿及估算见矿深度方面的地质找矿效果以及井—地磁测异常联合反演新技术的应用进行了论述。特别是井—地磁测异常联合反演新技术的应用,大大提高了井中磁测的定位技术和异常解释水平,为老矿山深部找矿提供了新的技术方法。 |
| 英文摘要: |
| Taking Daye iron mine of Hubei, Jinling iron mine of Shandong , Qian’an iron mine of Hebei and Mengku iron mine of Xinjiang as exampls, it is discussed that the geological prospecting effect of borehole magnetic survey in finding the well-blind ore and determining spatial location, forecasting the well-blind ore and estimating its ore-indicating depth, and the use of the new technology, which is joint inversion of surface-borehole magnetic anomalies. Particularly, the use of the new technology greatly improves the positioning technology and the interpretation of abnormality, providing new technical methods to deep exploration of the old mines. |
