摘　　要：老矿山资源危机迫切需要经济有效的找矿手段,在矿区外围寻找新矿段,增加开采储量。甚低频电磁法(VLF-EM)是可以选择的对象。在具备甚低频电磁法应用的地质、地球物理前提下,通过对所测数据进行技术处理,并且结合矿区地质研究控矿规律及矿体赋存规律,从而有效地圈定掩盖区异常地质体及其产状和展布方向,预测矿体空间赋存部位,为深部找矿提供依据。In order to find out new ore bodies and increase exploitation reserves, a economic exploration means is strongly needed in old mines. VLF-EM (very low-frequency electromagnetism) is a suitable mean to resolve problems. By means of exploration data processing, combined with the laws of exploration, it is confirmed that VLF-EM method can disclose the occurrence of abnormity body and confirm the place and distribution of ore bodies in the appropriate geology and geophysics regions suitable to use VLF-EM. VLF-EM method can be a guideline for the deep ore exploration.
