瞬变电磁法在煤炭勘查工作中应用已经很普遍,但多解性使其应用比其他方法(如直流电法、地震)在认识上更显困难。因此瞬变电磁法在煤炭勘查工作中应用要从孔旁实验入手,了解全区地质概况,为异常解释建立理论模型,结合实测数据处理,获得大量的定性、定量数据,通过图件上的异常特征分析、局部异常的认识,结合煤系地层的物性特征分析解释其构造形态。
Transient electromagnetic method has been widely used in coal exploration work, but its multiple solutions make it more difficult to understand its application than other methods (such as DC method and earthquake). Therefore, the application of transient electromagnetic method in coal exploration should start with hole-hole experiments, understand the geology of the whole area, establish a theoretical model for abnormal interpretation, and combine with the measured data processing to obtain a large amount of qualitative and quantitative data. Feature analysis, understanding of local anomalies, combined with the physical characteristics of coal measures stratigraphic interpretation of its structural morphology.
