ABSTRACT
This case history provides an overview of problems that have been investigated with electrical resistivity tomography (ERT) using 3D distributed arrays and presents the results from some of the surveys. 3D distributed arrays allow the placement of electrodes “around” features of interest either from the surface or in the whole space (underground or borehole deployment) by placing electrodes in x-y-z-planes. The investigations have included delineation of soil stratigraphy and types, tailings storage facility and power dam leakage paths, underground water and air-filled voids, and water flow in a mining environment. The case includes practical survey and planning considerations along with multiple examples of interpretations and results.
