| Abstract: | Based on the theory of wavelet transform and multi-scale decomposition of magnetic anomalies are analyzed. The theoretical model and practical analysis indicated that the wavelet and multi-scale analysis are usefule to establish the decomposed anomalies correlated to certain geological sources. The same method is utilized to process the actual data of a coal field. The processing result extrudes the anomalies of the fritted rock and compresses the irregular interference, which provides a more precice geological explanation. |
