Blasting operations generate seismic waves with different maximum velocity amplitudes and wide spectrum of frequencies. The intensity of seismic waves’ vibrations is proportional to the weight of the applied explosive. If the vibrations are sufficient in energy, surrounding buildings can be damaged or destroyed. Evaluating the negative effects of the blasting operations and quantification of the seismic safety is nowadays very actual and a challenging problem. The article presents the results of the analysis as well as an evaluation method of seismic safety of the objects during blasting work held by the law of decrease of the seismic wave amplitudes in Maglovec quarry. The results of the evaluation of seismic effects of blasting verified in a Maglovec quarry are the methodological base for evaluation of the effects of seismic blasting in all quarries in Slovakia.
