Description	Destress blasting is a very important proactive measure in areas of rockburst hazard in many mining regions. However, among the hard coal mining industry in particular, it is still not a popular choice. Destress blasting is used as a standard proactive technique in areas of high rockburst risk in longwall mining in the Czech part of the Upper Silesian Coal Basin (UCSB). Destress blasting is carried out in rigid competent rocks adjacent to coal seams at depths of 700 to 1000 m below the surface. Groups of boreholes (from 2 to 10) are fired with explosive charges of 500 to 4500 kg during longwall mining of thick coal seams (thickness from 4 to 6 m) ahead of the longwall face. The main goals of destress blasting are the softening of the competent rock layers for better caving, reduction of strain energy storage and rock mass stress release. Induced rockburst can be provoked in favourable conditions and such cases from locations in the USCB are described in the paper.
