摘　　要：为克服常规高密度激电法在有色金属勘探上深度不足以及常规激电测深效率低的缺点,引入不改变电极数,增加电极距的布置方式,通过特殊的采集方式得到可靠的原始数据。以西藏堆龙德庆县某矽卡岩型铜多金属矿床为例,为更好的确定该矿区岩体界线和蚀变带在空间上的分布,采用大极距高密度激电测深法对激电中梯异常区进行纵向评价,从而代替激电测深,达到浅部矿找矿的目的。应用结果表明,该方法在勘查有色金属矿效果显著,能够满足有色金属矿的勘探要求。In order to slove the problems of the small depth of the normal high-density induced polarization technique and the low efficiency of IP sounding,use the arrangement mode with long distance between electrodes. Use the special acquisition geometry can take the reliable data. Example for a mine located at Duilongdeqing Tibet. In order to find the boundary,use the induced polarization technique whith long distance between electrode. The results showed that： this method can meet the requirement of the non ferrous prospecting,we can use this method for non ferrous prospecting.
