摘　　要：通过开展瞬变电磁测量及相应的数据处理,建立了黑龙江响水河地区-350～-600 m视电阻率与不同岩性的对应关系,根据该地区岩性视电阻率的差异,划分了4个构造断裂带。根据围岩和矿石视电阻率差异大于两个数量级的关系,判断出矿石分布的空间位置,结合深钻孔实际验证,见矿率达到了75%,大大提高了矿山资源勘探效率。Through the Transient Electromagnetic Measurements（TEM） and the corresponding data processing,the corresponding relationship between the apparent resistivity of-350^-600 m and different lithologies are set up.According to the regional differences in apparent resistivity of lithology,it is divided into four fracture zones.Due to the apparent resistivity difference between rock and ore greater than two orders of magnitude,the spatial location of the ore is determined.With the actual verification of deep drilling,the rate of ore-finding reaches 75% with the efficiency of mining exploration greatly improved.
