摘要
介绍了井中瞬变电磁方法原理及资料解释原则。以江西相山CUSD3钻孔为例,通过对井中瞬变电磁实测资料分析,大致推断了钴孔周边铅锌矿化中心的方位,表明该方法在探测火山岩良导电体中具有较好的应用效果。结合岩心编录结果,认为该方法具有较高的探测精度,能够识别钻孔附近岩性界面、构造破碎等铀成矿、控矿要素,可辅助进一步的铀矿勘查工作。
This article introduced the theory and interpretation principles of BHTEM. A case study was made in deep borehole of CUSD3 for Uranium Science in Xiangshan. With field data analysis we inferred the orientation of the Lead-zinc mineralization center near the borehole, which shew BHTEM had an advantage in detecting good conductors in volcanic area. Combined with CUSD3, BHTEM is considered a useful method which has high detect accuracy, and can find out key uranium mineralization and ore-controlling factors, such as rock interface and faults near the hole, which will be very helpful to further exploration of uranium deposits.
