Effect of large-scale blasting on spectrum of seismic waves in a stone quarry

The article discusses the interaction between the groups of explosive charges installed at the free surface of rock exposure along the open pit mine perimeter. The spectrum analysis of the explosion-induced seismic waves shows that peak density frequencies of the seismic waves are governed by the formation of the canonical low-frequency components as a result of successive actuation of explosive charges, and are conditioned by hierarchical block structure of blasted rock masses.
