Abstract
This paper briefly introduces the basic principle and method of the EH-4 conductivity imaging system. The stability of the system, the ability for vertical electrical layered recognition, the detecting ability for typical electrical structure of the mining area and the usability of the system for complex conditions were tested by the test in the Leigou Mine Area, Mianchi County of Henan province. Through the application of wavelet multi resolution analysis mathematical method, the measured data has been processed by a first-order multi-resolution decomposition, and the data has been separated into first order detailed a-nomaly and approximation of abnormal. By contrasting with the information of the well ZK808 of mining area, it is illustrated that First order detail anomaly contains more noise and static effect and the first-order approximation abnormalities included the more target geological anomaly information, thereby effectively suppressing noise and static effect have been done, and the target geological anomaly information has been highlighted. Using a first order approximation of data, two dimensional joint inversion was done. By contrasting with the results of two-dimensional inversion and the mine area geological data, it is confirmed that the prospecting effect and the prospect of application of the EH-4 conductivity imaging system for exploration of bauxite deposits.关键词
