电法勘探是一种以研究地下探测目标体与周围介质之间的电性差异的地球物理探测方法，通常采用的二维电法勘探只能得到一条垂直于测线的视电阻率剖面，如果不能确定测线位置正好在异常体的正上方，这时就难给出较准确的结论。三维电阻率法采集数据量大，可获得三维电性数据体，而且可方便地根据需要实现水平及垂直切片，有着二维电法探测不能比拟的优点，实现对目标体的准确定位及全面透视。通过对构建的三维地质模型体进行数值模拟和物理模拟，表明双巷并行三维电法对地质异常体可以进行有效的探查并获得良好的探测效果。

The electric method is a kind of geophysical prospecting to study electrical property contrast between underground target and surrounding media. The commonly used 2D electric prospecting can only get an apparent resistivity section perpendicular to the pros-pecting line. If doubtful about the prospecting line is right above anomalous body, thus difficult to draw accurate conclusions. While the 3D resistivity method acquires large amount of data, can derive 3D electric data volume and horizontal, vertical slices conveniently as required. In comparison to 2D method, the 3D method has unmatched advantages, can realize target exact positioning and overall per-spective. Through numerical and physical simulations for 3D geological model established, indicated that the dual roadways 3D parallel electric method can carry out geological anomalous body prospecting with excellent effects.
