摘要：

This paper reports results from experimental studies of acoustic waves with amplitudes of 1-100 Pa from bulk blasts in opencasts. The wave shape, amplitude, duration, and pulse, and their dependences on the mass of the explosive at epicenter distances of 1-10 km are obtained. It is shown that the vibration amplitudes excited by acoustic waves acting on the frontage of multi-storey buildings are several times larger than those produced by seismic waves.
