摘　　要：为查明包头市固阳县矿集区的地层结构以及地下水污染情况,需在矿集区内典型矿山周边开展水文地质钻探工作。本文针对不同找水目标类型,应用高密度电阻率法测量技术,兼顾不同测量装置类型在分辨率、信噪比的优势,选用不同装置类型对矿集区内文圪气铁矿南选矿厂、鸿昌选厂、上十二份子金矿3个典型矿区周边含水地层的电性结构特征及成井模式规律进行了研究分析。研究表明,通过综合分析研究区的水文地质情况,选用不同高密度电法测量装置开展水资源调查是一种有效的技术方法,能够做到有的放矢,减少反演解释过程的多解性,提高了应用单一地球物理方法寻找地下水资源的效率,可为包头市固阳县矿集区找水定井提供技术依据。In order to find out the stratigraphic structure and groundwater pollution in the ore concentration area of Guyang County,Baotou City,it is necessary to carry out hydrogeological drilling around typical mines in the ore concentration area.In this paper,according to different types of groundwater-finding targets and the advantages of different measuring devices in resolution and signal-to-noise ratio,the multielectrode resistivity method was employed to study and analyze the electrical structure characteristics and well forming pattern of groundwater around south concentrator of Wengeqi iron deposit,Hongchang concentrator and Shangshierfenzi gold deposit.The result shows that comprehensive analysis of the hydrogeological conditions of the study area and utilization of different arrays of multielectrode resistivity method seem to be effective technical means for carrying out water resources investigation,which can achieve the target,reduce the multi-solution of geophysical inversion and interpretation,greatly improve the efficiency of searching for groundwater resources by using single geophysical method and provide a technical basis for water exploration and well determination in the ore concentration area of Guyang County,Baotou City.
