瞬变电磁法在煤田矿区水害防治中的应用

摘要

Coal bed water is always a serious hazard in coal production,while the transient electromagnetic exploration is currently very important mine water prevention geophysical method.In the actual production practice,because of the transient electromagnetic method has a cost⁃saving,high precision,easy to operate features,which are widely used.In this paper,the transient electromagnetic method have a brief introduction of the principle and data processing interpretation,in combination with the actual production process of a mining are⁃a of exploration data,the transient electromagnetic method in detection of coal mine containing water is analyzed,found that the method can identify abnormal water area,especially in the composite seismic exploration data,the abnormal water area dividing precision is im⁃proved,the use of the method to detect abnormal water area accumulate experience in the future production process,as well as the meth⁃od of the prevention and control of water disasters applications in coalfield provide the beneficial reference.%煤层水一直是煤矿生产的重大隐患，而瞬变电磁勘探是目前煤矿防治水工作中的比较重要的物探方法。在实际生产实践中，由于瞬变电磁法具有节约成本、精度高、易操作等特点得到广泛应用。介绍了瞬变电磁方法原理及资料处理解释，结合在实际生产过程某矿区的勘探资料，对瞬变电磁法在探测煤田矿区含导水情况进行了分析，发现该方法能较好识别富水异常区，尤其在综合地震勘探资料后提高了划分富水异常区精度，不仅为将来生产过程中运用该方法探测含导水情况积累了经验，也为该方法在煤田防治水害方面的应用提供有益的参考。
