Geoelectrical imaging in the interpretation of geological conditions affecting quarry operations
(2010) In Bulletin of Engineering Geology and the Environment 69(3). p.465-486- Abstract
- Determination of the subsurface geology is very important for the rock quarry industry. This is primarily done by drilling and mapping. However, in Sweden, the bedrock is often completely covered by Quaternary sediments, making the prediction quite difficult. This study shows that electrical resistivity imaging together with induced polarization proved to be very efficient in detecting fracture frequency, major fracture zones and variations in rock mass quality, all of which can affect the aggregate quality. These techniques can also determine the thickness of the overburden. Furthermore, by doing 2D-parallel data sampling, a 3D inversion of the dataset is possible, which greatly enhances the visualization of the subsurface. Implementation... (More)
