The group winning blasting is one of the most often applied method ofhigh-energy tremors provoking in underground mines of the Lower Silesian CopperBasin. The simultaneous detonation of dozens mining faces are performed inorder to release of elastic energy which is cumulated in surrounding rock mass.The accuracy of currently used non-electric initiation systems is insufficientto provide a controlled interference of seismic wave generated by blastingworks. As a result, simultaneous detonation of higher number of mining facesdoes not always correlate with improvement of the effectiveness of rockburstprevention. In this paper, the records of seismic waves generated by blastingworks in one of the mining panels from the Polish copper mine were analysed.The evaluation was performed by correlation of selected blasting parameterssuch as the number of fired mining faces and the total amount of detonatedexplosives with parameters of induced seismic wave
