| Abstract: | Resistivity tomography, an advanced technique reconstructing resistivity image from a series of potential survey of electrode
arrays is quite different from the non-linear inversion of wave problems. The main problem in the resistivity reconstruction
is how to solve the Poisson’s equation of direct current fields in voluminous media and to complete the inversion iteration
efficiently. A mathematical idea of cascade algorithm proposed by Shima (1992), as an example, is introduced briefly in this
paper. The emergence of water flood in tunnels in Wennan Coal Mine, Shandong Province, gave us chances to carry out hydrogeological
exploration twice using resistivity tomography in 1995–1996. Three profiles with a total length of 5832 m and a maximum depth
of 120 m in tomograms are completed. The series of resulting tomograms distinctly reveal the distributions of stratigraphic
structure, mined-out areas, fracture zones, crack belts and piping water-loss zones. These results from tomograms are verified
by drill records and then successfully adopted in the followed hydrogeological engineering in the coal mine. Finally, the
authors discussed the technical method and existing problems in resistivity tomography.
