Abstract

Until now, the layer sequence "rock-coal-rock" and faults in coal seams in underground hard coal mines have been detected by seismic waves and geoelectric measurements. To determine the geometrical and petrophysical parameters of bedrock and coal, the data recorded using seismic and geoelectric methods have been inverted independently. In consequence, the inversion of partly inaccurate data necessarily resulted in a certain degree of ambiguity.
