电磁法在有色金属矿产勘查中的研究进展

Research progress of electromagnetic method in non-ferrous metal mineral exploration

电磁法勘查是指相关工作人员通过观测到的电磁场响应,结合该地地质类型,推断地下阻断率空间分布特征,进而完善有色金属勘查工作的过程。目前,电磁法技术的类别按照接收信号组成分可分为时间域电磁法和频率域电磁法,二者可勘测深至数十公里的深度。本文简述电磁法的技术类别及勘查理论,介绍电磁法在有色金属矿产勘查中的应用情况,展望电磁法的未来前景,为后续研究工作提供借鉴和参考。

Electromagnetic exploration refers to the process in which relevant personnel infer the spatial distribution characteristics of underground blockage rate based on the observed electromagnetic field response,combined with the geological type of the area,in order to improve the exploration of non-ferrous metals.At present,the types of electromagnetic technology can be divided into time domain electromagnetic method and frequency domain electromagnetic method according to the composition of the received signal,both of which can survey depths up to tens of kilometers.The article briefly describes the technical categories and exploration theories of electromagnetic methods,introduces the application of electromagnetic methods in the exploration of non-ferrous metal minerals,and looks forward to the future prospects of electromagnetic methods,providing reference and guidance for subsequent research work.
