Interpretace napětí na základě řešení ohniskových mechanismů
Ptáček, Jiří ; Mořkovská, E.
Knowledge of stress strain fields and their development is the fundamental for all mine working and for its right planning most importantly in the rock burst risk regions. A model of recent stress fields in the Czech part of the Upper Silesian Coal Basin has been interpreted. Stresses causing Variscan structural tectonic pattern in USCB based on paleostress analyse have been took for starting point of research. It was took account the influence of Alpine deformation due to Carpathian nappes. There were more stress tensor gauging realised for recent stress state 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.
