摘      要：Mining-induced seismicity occurs in numerous underground mines worldwide where extraction is conducted at great depths or in areas characterised by complex tectonic *** is accompanied by rock bursts,which result in the loss of working functionality and the possibility of accidents among *** issue of a constant and reliable seismic hazard evaluation is of key signifcance for both the safety of miners and the stability of *** on its improvement is directed at developing new interpretive solutions and *** nature of the presented solution is the complex interpretation of seismological data that characterise rock mass seismicity and of underground measurement results in the form of a map presenting the longitudinal wave propagation velocity distribution in the rock surrounding the mined coal *** solution was tested in hard coal mines located in the Upper Silesian Coal *** mines are equipped with a modern seismological system enabling the constant monitoring of seismicity together with hazard level evaluation as well as with seismic apparatus for conducting periodic measurements of the seismic wave propagation velocity before the mining *** seismic hazard evaluation criteria were determined based on the obtained results,involving the anomaly of the Gutenberg–Richter law“bvalue and the maximum longitudinal seismic wave propagation velocity in the roof *** obtained experience and the result validation of this new comprehensive hazard evaluation method confrm its practical usefulness and indicate the directions of improvement for the solution in question.
