摘要
阐述矿井瞬变电磁法的物性前提、方法理论及基本原理。简单讲述了引发矿井水害的直接因素。为排除此类安全隐患,利用矿井瞬变电磁法对掘进巷道进行超前探测。通过实例研究论证矿井瞬变电磁法对于地质异常预报工作具有较好的应用效果,可查明矿区隐伏地质灾害,在煤矿生产过程中起到了关键性的安全指导作用。
This paper states the mine transient electromagnetic method including physical premise,theory and basic principle. It simply tells the story of the direct factors leading to mine water disasters. To rule out such security hidden danger,the mine transient electromagnetic method is used in roadway advanced detecting. Having found out the concealed geological disasters in mining area,the mine transient electromagnetic method has played a key role in the process of coal mine production safety for good applications effect in abnormal geological forecast.
