Abstract: Rock burst events with focus area outside of the coal seam are desrcibed. Such rock bursts are in the Ostrava-Karviná Coal Basin usually induced by mining in stratigraphic lower seams with overlying 100 m thick solid roof zone developed without any workable coal seam. The process of rock massif failure in such conditions is described Deformation and failure connected with restoring new equilibrium condition could be manifested then by destruction even in mine workings located in considerable distance from rock burst focus zone.
