在煤田开采过程中,矿井水害一直威胁着煤矿的开发和安全。要减少和杜绝水害关键在于找到水源,瞬变电磁法是目前寻找水源的最好方法之一。本文阐述了瞬变电磁法的发展概况、原理方法、特点及应用领域。最后通过应用实例,介绍瞬变电磁法在矿井水文地质勘探中的应用效果。
Mine water hazards have been a threat to the development and safety of coal mines during coalfield mining. The key to reducing and eliminating water damage lies in finding sources of water. TEM is one of the best ways to find water sources. This article describes the development of transient electromagnetic method, the principle and method, characteristics and application areas. Finally, the application of transient electromagnetic method in mine hydrogeological exploration is introduced.
