摘要
老矿山深部、外围找矿是当前"以矿找矿"为重要方式。文章以福建某铅锌矿为例,通过坑道内开展小线框、大电流的瞬变电磁法获取电阻率异常,利用坑内钻进行验证,取得了良好的找矿效果,为老矿山勘探提供了新的有效的物探方法。
The periphery and to depth of the old mines are the key points for ore prospecting breakthrough at present and in the future.A Pb-Zn mine in Fujian province is an example where TEM（Transient Electromagnetic Method）with small coils and big current is carried out in the tunnels to achieve resistivity anomaly.The anomly is checked by tunnel drilling with good results thus TEM is an effective method for ore prospecting in the old mines.
