Numerical models of quarry blast sources: The effects of the bench. Technical report, 1 November 1992-15 April 1993

; ; ;
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.
