Assessment of seismic effects during mining

The large application of the blasting technique in engineering arises from the fact that one
blasting replaces months of work by machines and people. Wide application of the mining technique is
due to the fact that during blasting the seismic impacts can be controlled and reduced to a minimum
level. Today, blasting is often carried out in the immediate vicinity of various objects, buildings,
factories, and even refineries, hydro facilities and nuclear power plants.
The assessment of blasting effects presented in this study is based on analytical calculations and widely used empirical relationships, with particular emphasis on the estimation of seismic impact through the Sadowski equation. The results for four minefields with explosive charges ranging from 100 kg to 3000 kg provide a comparative overview of how increasing explosive quantity influences
fragmentation, airblast pressure, and ground vibration intensity.
