摘　　要：鸡笼山金铜多金属矿位于丰山矿田的西南部,处东西向鸡笼山—苗母山复式向斜与北东向坡山—李家湾断裂带的交叉部位。矿山经过多年的开采,部分地段已达到设计开采标高,以往探明的资源储量已大部分开采完毕,矿山处于严重危机状态,迫切需要寻找接替资源。本文结合区域地质、地球物理等方法,在原矿区深部及外围开展了以高精度重力、磁法、激发极化法和可控源音频大地电磁法为组合方式的综合物探找矿实践,以圈定矿区深部及外围成矿有利部位,为后期地质钻探研究工作提供参考。The Jilongshan gold-copper polymetallic ore deposit is located in the southwestern part of the Fengshan ore field, at the intersection of the east-west chicken-mountain-Miaomushan syncline and the northeast-slope-mountain-Lijiawan fault zone. After years of mining, some mines have reached the design and mining elevation. Most of the proven resource reserves have been mined in the past, and the mine is in a state of serious crisis. It is urgent to find replacement resources. In this paper, combined with regional geology, geophysics and other methods, a comprehensive geophysical prospecting practice based on high-precision gravity, magnetic method, induced polarization method and controllable source audio magnetotelluric method is carried out in the deep and peripheral areas of the original mining area to define the mining area. The favorable parts of deep and peripheral metallogenesis provide reference for the later geological drilling research work.
