... Abstract Coal exploitation in the Upper Silesian Coal Basin is associated with rockburst hazard. This hazard is minimalized by active rockburst prevention, where torpedo blastings in roof-rocks take very important place. The estimation of the torpedo blasting effectiveness becomes significant...

... ABSTRACT The exploitation of deposits is a limited activity in time and soon or later every mine exploiting the given deposit will come to a phase of liquidation, which is accompanied by termination of pumping out the mine waters. This is shown by a rise of the groundwater table in the region...
