Abstract: The DC resistivity method is widely applied in the mine to find abnormal water bearing body, three-dimensional electrical method based on 2D graphics can directly show the 3D geometric model based on the application of pseudo 3D high density resistivity detection, according to the continuity of geological structure between 2D planes, the measurement data can be combined into approximate three-dimensional 3D geological model. We select the accurate diode detection device and use WGMD-4 high density electrical system, and apply smooth constrained least squares inversion method to carry out cyclic iterative processing of detection data. Through comprehensive static correction technique, the slice data body was obtained by three-dimensional visual slicer dicer system and the abnormal low resistivity range is delineated to ensure the accurate judgment of mine abnormal water bearing body.
