![]() ![]() The concepts of electrical resistivity variation with rock mass fracture intensity, and aperture were used to obtained experimental data. The method was applied in an experimental test to investigate ER response with varying fracture intensity I f and aperture size Aper width in an experimental set-up at Kwame Nkrumah University of Science and Technology (KNUST, Kumasi, Ghana, geotechnical laboratory. The Electrical Resistivity (ER) method is one of such methods. Geophysical methods have been used to detect contrast in subsurface material. Fracture geometric characteristics (FGC) such as fracture intensity, fracture network connectivity and aperture distribution are crucial features controlling the hydraulic and geotechnical properties of rock formations. ![]()
