瞬变电磁法在吉林省头道沟煤炭普查中的应用

The application of the transient electromagnetism method to coal census in toudaogou Jilin

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。

It is very common to apply the transient electromagnetism method to coal investigation,while the application of multiple solution is even harder to other methods（such as direct current method,earthquake）.Consequently the application of transient electromagnetism method to coal investigation should begin with the bore tests beside to know the whole area geology situation,and to build theoretical models to excrescent explanation.In this paper,a lot of qualitative and quantitative data are acquired in combination to the disposal to actual test data,then its structural form is explained through analyzing the excrescent characteristic of the specimen,understanding part abnormality,and with the characteristic of coal geological rock strata.
