Using DC resistivity ring array surveys to resolve conductive structures around tunnels or mine-workings
Michael Albert Mitchell, Douglas W. Oldenburg
2023, Journal of Applied Geophysics (211)
In underground environments, conventional direct current (DC) resistivity surveys with a single linear array of electrodes produce fundamentally non-unique inversions. These non-uniqueness and model resolution issues stem from limitations placed on the location of transmitters (TXs) and receivers (RXs) by the geometry of existing tunnels and boreholes. Poor excitation...
