常用多金属矿CSAMT反演方法研究与对比

Research and comparison of CSAMT inversion methods for commonly used polymetallic ore deposits

在矿山地质勘探工作中,反演方法的选择事关重要,而针对多金属矿的地质条件,应选用不同的方法。本文主要探讨了CSAMT方法下的Bostick反演、奥克姆(Occam)反演、快速松弛(RRI)反演、共轭梯度(NLCG)反演的应用。分别简述了这四种反演方法的原理以及区别。讨论四种反演的优点缺点并且结合实例探勘对比了这四种方法对多金属矿的反演效果。

In mine geological exploration,the selection of inversion method is very important,and different methods should be selected for the geological conditions of polymetallic ore.This paper mainly discusses the application of Bostick inversion,Occam inversion,RRI inversion and NLCG inversion under CSAMT.The principles and differences of the four inversion methods are briefly described.The advantages and disadvantages of the four inversion methods are discussed,and the inversion effects of the four inversion methods for polymetallic ore deposits are compared with examples.
