瞬变电磁法在煤炭勘查工作中应用已经很普遍,特别是在煤矿采空区及积水采空区勘探中应用效果更加明显。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。

The transient electromagnetic method is widely applied in the coal exploration work,especially in coal mined-out area and mined-out area with water exploration.It should make experiment in the side of the drill holes to master the geological data of the whole area,establish theory model for anomaly interpretation.Through the measured data processing acquire a mass of qualitative and quantitative data.Through the anomaly character analysis and part anomalies in the maps,combining with characteristics of coal measure strata,interpreted its structural form.
