时间域瞬变电磁在玄武岩盖层区煤田勘探中的应用

Application of the time domain transient electromagnetic method in basalt covers coal exploration

玄武岩盖层下固体矿产的勘探工作,一直没有取得良好的效果,通过普通物探手段难以穿透由玄武岩盖层所引起的高阻层,随着物探技术方法的不断革新,时间域瞬变电磁法(TDEM)可以有效的穿透中厚、巨厚玄武岩高阻层,且对盖层下隐伏矿体的地质情况,有较清晰的揭露,达到了良好的效果。

The exploration work of solid mineral under the basalt cover has not achieved good results, through the common geophysical prospecting methods are dififcult to penetrate the basalt cover layer caused by the high resistance layer, with the innovation of new geophysical exploration methods, time domain transient electromagnetic method （TDEM） can effectively penetrate mega-thick basalt, has a clear open to concealed ore body geology under the cover , and achieved good effect.
