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