基于RRI反演的高频大地电磁测深在深边部矿产勘探中的试验研究

随着我国国民经济的快速发展,对各种矿产资源的需求量越来越大,经过多年对近地表的矿产开采之后,找矿的目标逐渐向矿区深边部发展,本文阐述采用EH-4电导率成像系统的高频大地电磁法,并且利用RRI反演,能够准确快速地探测大深度范围内的矿化异常,对矿区的深边部矿产的赋存状态进行超前地宏观预测,并将野外的成功实例进行分析.

The test research of high frequency MT based on RRI inversion in exploring deep and limbic minerals

With the fast development of the national economy in our country, the requirement of minerals resource is increasing. After mining near-surface minerals for many years, the prospecting object is gradually extending to deep and limbic subsurface. This paper describes the principles of high-frequency MT using the EH-4 electric conductivity imaging system, and to truly and rapidly explore mineralization anomalies in big and deep areas by using RRI inversion. At the same time, we also can macroscopically forecast the existing status of the minerals in deep and limbic subsurface by using the above-mentioned method, and we have analysed field examples successfully.
