Numerical Models of Quarry Blast Sources: The Effects of the Bench

Abstract

A set of finite difference calculations were performed to modal the effects of a quarry bench on the excitation of seismic signals from a quarry. This work complements other S-CUBED research on the nonlinear behavior of the quarry blast source (spall from the quarry face) and interference effects from ripple-fired explosions. We find that the excitation of seismic phases depends strongly on the location of the explosion source near the quarry face.
