WebIn this model, the dominant frequency and amplitude of blast-induced seismic waves are mainly influenced by the initial pressure and the adiabatic exponent of explosives in the same medium. The dominant frequency increases with the decreasing initial pressure or the increasing adiabatic exponent. WebDec 1, 2012 · The nature of seismic waves from explosive sources in boreholes has been studied. Seismicity is measured by high-frequency high-amplitude triaxial accelerometers. Amplitude and frequency of blast seismic waves are dependent on initiation mode. Measured direct/reverse ratio of PPV is greater than 4 in 3 and 6 m explosive columns. …
