A model of recent stress fields in the Czech part of the Upper Silesian Coal Basin (USCB) has been interpreted. Stresses causing Variscan structural tectonic pattern on USCB, based on paleostress analysis, have been used for the starting point of the research project. It was taken into account the influence of the Alpine deformation due to Carpathian nappes. There were more stress tensor gauging realized for recent stress strain determination in the region above all using hydrofrac and treated overcoring methods during last ten years. It´s becoming apparent that for information of recent stress fields is usable the interpretation of focal mechanisms of energetic significant mine induced seismic events which were observed here more than ten years.
