Abstract Basic thinking of the second order difference section is described in this paper. In the application of the highdensity resistivity method to exploring concealed karst and underground rivers in a certain tailing sand bank, quite abundant geological information was obtained by introducing the second ore difference section, and hence fairly satisfactory geological results were attained.
