Feasibility study of inhomogeneity detection by means of microseismic and electric resistivity measurements in crystaline rocks
Abstract
The aim of the presented study was an analysis of possibilities for detection of inhomogeneities, in particular the type of cracks and cracks in crystalline rocks by in-situ geophysical measurement. An overview of the resolution and detection capabilities of selected geophysical methods was done.
In the case of seismic measurement, it is mainly the relationship between the used measurement methodology, the seismic source and the properties of non-homogeneous environments that can be detected. In the case of electrical resistivity tomography, the study focuses on the use of a resistor network model and its use for the detection of cracks and crack systems in crystalline rocks.
This is an original and new approach to addressing this issue. This approach is based on computer modeling and a new computing process, developed at the Faculty of Science, Charles University.
