小波多尺度分析在煤田火烧区磁法探测中的应用

Application of wavelet multi-scale analysis in magnetic prospecting of the burnt coal area

根据小波多尺度分析原理,分解磁异常。理论模型及实例分析表明,小波多尺度分析对分解后的磁异常,可按需要区分不同地质意义,突出目标地质体,抑制干扰,划分煤田的火烧区烧变岩边界。

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.
