Abstract
The authors report measurement data on seismic waves in bulk blasting at quarries by using new high-precise electronic and pyrotechnic blasting systems. It is proved that both systems are efficient, intensity of seismic waves is much lower in large-scale bulk blasting. The authors implemented numerical modeling of seismic wave propagation under a short-delay bulk blast at a quarry. Influence of the blast delay parameters and their precision on the maximum level of seismic vibrations has been studied, and their optimal ranges have been established.
