摘要
如何通过改进矿井瞬变电磁法反演方法来提高解释精度一直以来都是瞬变电磁研究领域的重要课题。在分析总结目前矿井瞬变电磁法反演方法的基础上,将其分为定性近似反演、基于目标函数迭代反演和联合反演3类,并探讨了不同方法的特点、优势、局限性及改进方法。通过对矿井瞬变电磁法反演发展趋势的分析,提出发展全空间反演理论和方法、进行多方法尤其是非线性方法的联合反演以及多维反演是实现井下精细探测和定量解释的主要发展方向。
How to improve the accuracy of data interpretation by improving the mine transient electromagnetic inversion methodshas always been an important issue for the study of mine transient electromagnetic method. The mine transient electromagneticinversion methods are classified into qualitative approximate inversion method, the iterative inversion method based on theobjective function and joint inversion method, and a general review of their characteristics and limitations are discussed. Byanalyzing the development tendency of mine transient electromagnetic inversion, we can come to a conclusion that improving thetheory and method of total space inversion, studying on joint inversion especially in nonlinear way as well as multi-dimensionalinversion would be the trend of detailed detection and quantitative interpretation.
