Paper Title:
Research on the Influence of Electrode Trends and Noise Suppression by Inversion Correction Method in Deep Mine Resources Prospecting by CSAMT
  Abstract

The mine prospecting has been entered into the key stage of “overcoming depth and finding blind” in our country at present. This article simulates the relationships between temperature, concentration and electrode potential by Nernst equation. And then, the characteristics of electrode trends and the influences to the deep mine resources prospecting using CSAMT are discussed. Finally, trends suppression by inversion correction method is studied combined LOTEM data. The results show that trends are produced in the electrode potential by the change of temperature and concentration. Trend noises display in two manners, relatively linear and nonlinear, and the spectrum of trends mainly focuses on or near the zero frequency. Positive trends lift the resistivity values of deep low resistivity object, and negative trends lower the resistivity values of deep high resistivity object, so the trends lead to wrong explanation results. Finally, the inversion correction method combined with LOTEM data can remove the trends successfully and is very important to the solution of mine crisis in our country.
