Structural and stress analysis in mining practice in the Upper Silesian Coal Basin

Autor: Ostrava Poruba, Petr Waclawik, Radomír Grygar

The irregular distribution of stress in rock mass is a decisive factor for the origin of rock bursts. Besides, a sound knowledge of stress distribution is very important in the excavation of mine workings. Stress state is affected both by natural str
