摘　　要：在铁矿开采过程中,经常会遇到断层破碎带、软弱夹层及含水异常体等不可直接预测的不良地质构造,不及时预测及治理将影响安全生产。在诸多的预测方法中物探技术以其无损、准确、高效、快捷而得到认可。其中,矿井瞬变电磁对存在视电阻率差异的岩性响应明显,其探测结果能准确区别岩性电性变化界面,在很多煤矿防治水工程中得到了印证。本文在简单介绍矿井瞬变电磁基本原理及精细探测技术的基础上,结合大牛铁矿实际地质情况,通过具体的探测实例的尝试,阐述了矿井瞬变电磁精细探测技术在铁矿防治水中的作用。In the iron ore mining process,often encounter fault belt,soft interlayer and abnormal water-bearing body can not be directly predictive of adverse geological structure,not timely prediction and management will affect the safety in production.In many prediction methods,the geophysical technology has the advantages of nondestructive,accurate,efficient,fast and get recognition.Among them,the mine transient electromagnetic resistivity difference of existence of the lithology response significantly,the detection result can accurately distinguish the lithology changes of electric interface,in a lot of mine water control project has been confirmed.The paper introduces the mine transient electromagnetic principle and fine exploration technology based on combination of the actual geological condition,big iron mine,through specific probe instance attempts,elaborated mine transient electromagnetic fine exploration technology in iron ore mine water prevention and control effect.
