Detection of old mines in Nízký Jeseník Mts. by using of electrical resistivity tomography: comparison of methods
Abstract
The electrical resistivity tomography (ERT) belongs to the methods widely used in geology and geomorphology research (e.g. investigation of landslides and debris flows structure). At present, these methods are often used as a tool for detection of sub-surface cavities in karst and pseudo-karst terrains. Analogically, the ERT could be useful instrument applied during the detection of old mines. There were two underground mines in sedimentary rocks investigated by methods of Wenner-Schlumberger and dipole-dipole. The results were compared with each other and with the real position of the quarries.
