Rockburst in Ostrava-Karvina Coalfield

Original language description

More than 450 rockbursts, many of them with fatal consequences, have been monitored in Ostrava-Karviná Coalfield since the start of the last century. Right from the start of their appearance, miners have made efforts to avoid them or at least to reduce their consequences. Many researchers and geomechanical experts have explored the rockburst mechanism, its regularities and natural relations. Nevertheless, there are many things about rock mass properties and rock mass behavior that we do not know yet. Together with gaining valuable knowledge, the development of rockburst protection methods was achieved. The development of prognosis and prevention methods as well as a contemporary system for their application in the coal mines in Ostrava-Karviná Coalfield is described in the contribution. It considers the history of rockburst cognition, reflecting new experience and consequently new opinions on the mechanism of different types of rockburst in the specific geological conditions in the Upper Silesian Coal Basin. Geomechanical methods comprising destress drilling, destress blasting and seams watering as well as geophysical methods of rockburst prediction and prevention are presented. All are supplemented by examples of the application of protection methods in coal mines where there is a risk of rockburst. Opinions on the effectiveness and usability of individual methods of rockburst prevention based on practical experience are stated in conclusion.
