T. 4

Blasting has positive effects and negative impacts causing damage to surrounding civil objects. The intensity of seismic waves’ vibrations is proportional to the weight of the applied explosive. If the vibrations are suffcient in energy, surrounding buildings can be damaged or destroyed. Evaluating the negative effects of the blasting operations and quantifcation 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 seismic waves’ attenuation law in Dubina quarry. The results of the evaluation of seismic effects of blasting verifed in a Dubina quarry are the methodological base for evaluation of the effects of seismic blasting in all quarries in Slovakia.
