摘　　要：哈达门沟金矿位于内蒙古包头市九原区境内,是我国华北地区重要的金矿集区。随着勘查工作的不断深入以及对已发现中浅部矿体的不断开采,矿区深部找矿工作的重要性日益凸显。这里以探查控矿构造为切入点,综合测量矿区内地质结构的电性特征,定位赋矿构造。在连续测量的940剖面线、980剖面线与1020剖面线中,赋矿构造显示出高-低阻、中高-低阻梯度带的特性,结合地震剖面资料及实际勘查工作现状,初步实现了对深部矿体进行探测研究与评价工作。提出了山前断裂带,是与哈达门沟金矿的成矿作用密切相关,其为成矿提供了深部物质与能量来源,并控制着矿体的地表展布形态与深部延伸情况。基于本次地球物理测量工作,为矿区的深部找矿勘查工作提供了借鉴。Hadamengou gold deposit,located in Jiuyuan district,baotou,inner Mongolia,is an important gold concentration area in North China.With the continuous exploration work,deep and surface veins have been discovered and mined,the importance of deep prospecting in mining area is increasingly prominent.Through the method test,the measurement method of CSAMT is determined in this area.Taking the exploration of ore control structure as the breakthrough point,the electrical characteristics of geological structure in the mining area are comprehensively measured,and the ore bearing structure is located.In the continuously measurements on the profiles of 940,980 and 1020,the ore bearing structure shows the characteristics of high low resistance and medium high low resistance gradient zone.The exploration and evaluation of deep orebodies are realized by comprehensive analysis.According to the seismic profile data and the actual exploration status,it is proposed that the piedmont fault zone is closely related to the mineralization of Hadamengou gold deposit.This provides deep material and energy sources for mineralization,and controls the surface distribution form and deep extension of ore bodies.Based on the geophysical survey work,it provides a basis for the deep exploration work in the mining area.
