摘　　要：简述了高密度电法勘探技术的基本原理以及在应用中应注意的关键技术问题及其处理方法。通过布置在地面的所有电极对地层进行电阻率采集,然后在二维电阻率反演软件中得到二维电阻率断面图。最后运用RViewe反演软件得到电阻率的三维栅栏图。三维反演解释结果客观地反映了采空区的范围以及隐伏水源空间位置,为矿井防治水工程提供了准确信息。通过在某矿的应用实例,说明高密度电法三维成像技术在煤矿采空区探测领域中具有较好的探测效果。It not only describes basic principle of High-density Resistivity Method, but also presents solutions to key technical problems which were met in application. All the electrodes are arranged to data acquisition of ground resistivity, 2D resistivity cross section diagram which obtained in 2D resistivity inversion software, is changed into 3B fence diagram through RViewe inversion software. The 3D diagram objectively reflects the range of the gob and spatial location of buried water, as meanwhile it provides useful accurate information for the Mine Wa-ter Control Project. It shows that High-density Resistivity Method with 3D imaging techniques has better effect on the detection through examples in some coal mine.
