Rock bursting is a particular hazard in the underground coal mines of Poland due mainly to the physical-mechanical properties of the rock and the geological-tectonic structure of the Upper Silesian Coal Basin. Mining and geophysical methods of predicting and preventing rock bursts are discussed. These include: seismologic methods, various kinds of shock blasting, torpedoing, and injecting water under high pressure. Thanks to this multidirectional activity, a decrease of rock bursts and their effects has been noted in the postwar years of Polish coal mining. These results were obtained in face of a continually growing potential threat from rock bursts caused by (1) the systematic increase of extraction from rock bursting strata, (2) exploitation at gradually greater depths along with (3) the extension of exploitation into deposits enclosed in different types of pilars and other parts of deposits surrounded by workings. Despite the achievements of science and mining practice in this field, this threat has not yet been fully studied and controlled as it should be. As a result, research on preventing rock bursts is being continually widened. This research has a complex, multistaged and long-range character. Theory, laboratory and field work in the mines are working on a solution to the problem.
