Abstract
Karviná region, part of the Upper Silesian Basin (Czech Republic and Poland), where intensive mining induced seismic events have been documented for a long time, is the area with underground exploitation of black coal. This exploitation manifests also as negative effects on the surface, mainly deformations of surface, changes of hydrogeological conditions and induced vibrations. Experimental investigation documents intensive vibrations that for more intensive mining induced seismic events exceed the value of 10 mm/s. One example from interpretation using time-frequency map of measured digital signal is included.
