夏日哈木铜镍矿区瞬变电磁法有效性试验

The method effective experiment of transient electromagnetic in xiarihamu nickle copper

为了使新的物探方法技术更好地服务于祁漫塔格地区的找矿工作,在综合考虑矿床类型、方法技术优缺点等因素的基础上,在夏日哈木铜镍矿区选择有利成矿地段开展物性测量以及地—井、地面瞬变电磁方法有效性实验。实验结果表明该地区岩(矿)体具有"低阻、高极化、高密度、强磁"的特征,具备开展物探重、磁、电勘探的物性前提,地—井、地面瞬变电磁法测量结果异常明显,与实际钻孔资料和地质剖面吻合较好。瞬变电磁法有效性试验成果显著,达到了预期效果,为后期在祁漫塔格地区开展铜镍矿调查提供了实用、有效的方法技术支撑。

In order to make the new technology of geophysical to better service for prospecting in Qimantage area. Based on integrated consideration about the deposit type, method and technology advantages and disadvantages and so on, we select Xiarihamu copper nick?el mine as experiment area .the methods including physical measurement, downhole TEM and ground TEM, The results show that the rock ( ore) with“low resistivity, high polarization, high density, strong magnetic”, it?s also indicate that this area has the prerequisites for gravity, magnetic and electrical exploration. The downhole and ground TEM method experiments results are in good agreement with the actual drilling data and geological profile. Transient electromagnetic method validity test achieved the desired effect. It supplies an effective and practical geophysical method for copper nickel mine prospecting in Qimantage in future.
