摘　　要：根据前期对阿舍勒铜矿床成矿规律的了解,结合钻探、化探及地质资料综合分析,可知矿区主要矿体Ⅰ号矿体北部呈隐伏状,并具有继续北延、深度逐渐加大的趋势,为深、边部找矿提供了良好的试验地点。本文介绍了激发极化法与可控源音频大地电磁法(CSAMT)在探测深部硫多金属矿体中的优势及其工作方法;在试验区进行激电中梯、可控源音频大地电磁法(CSAMT)组合勘探,测量结果充分验证了Ⅰ号矿体的北延趋势,可控源音频大地电磁法二维反演剖面较好的反应了Ⅰ号矿体"U"字型空间展布特征。Based on the metallogenic regularity of the Ashele copper ore deposit in combination with drilling, geochemical and geological data, the authors found that the northern part of No. I ore body （the major ore body） is in the concealment state and tends to extend northward accompanied by increasing depth. This discovery has provided a favorable test place for deep and edge prospecting work. This paper deals with the advantages of the IP and CSAMT methods in the exploration of deep sulfide polymetallic ore bodies and the practical working procedures. The combinational exploration composed of IP central gradient array amd CSAMT was carried out in the test area, and the result has fully verified the northward extension tendency of No. I ore body. The two- dimensional inversion profile can fairly well reflect U-shaped spatial distribution of No. I ore body.
