Coal Mining R&D Projects GA105/08/1625 GA ČR - Czech Science Foundation (CSF) CEZ AV0Z30860518 - UGN-S (2005-2011) Annotation Knowledge of stress strain fields and their development is the fudamental for all mine working and for its right planing most importantly in the rock burst risk regions. A model of stresses causing Variscan structural tectonic pattern in the Czech part of Upper Silesian Coal Basin (USCB) based on paleostress analyse have been interpreted. It was compiled used many of tectonic measurements of planar and linear elements and comparison with the knowledge of dynamic development of Variscan body in a larger framework of Moravo Silesian zone. It was took account the influence of Alpine deformation due to Karpatian nappes. There were more stress tensor gauging realised 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 focus mechanisms of energetic significant seismic events, which were observed here more than ten years.
