| 摘 要： | 随着已知矿产储量的不断减少,在矿山外围及深部采用以矿找矿方法成为延续矿山服务年限的重要手段。在矿山已有坑道内进行相关物探工作具有投入少、见效快等优点。瞬变电磁法(TEM)因其工作装置的灵活性、快速性和有效性逐渐受到重视。文章通过以小线框、大电流的瞬变电磁法在羊拉铜矿已有坑道底板进行勘查工作,结果显示该方法应用于坑道内效果明显,为以矿找矿提供了新的途径。

| Abstract: | Along with the continuous reduction of the known mineral reserves the method of prospecting unknown ore according the known ore has been applied to prospecting in the periphery and to depth of the known ore deposit and become an important mean to extend the service life of mines.Geophysical explora tion in the existing tunnel of mines has the advantages of a little investment and quickly obtaining effect.Transient electromagnetic method (TEM) is flexible,rapid and effective and is gradually has been paid much attention.Small line frame and large current TEM survey is carried out at the existing tunnel floor of Yangla copper deposit and the result shows that it is quite effective and provides a new way for ore propecting. |
