ABSTRACT: Full-waveform signals of mine-induced seismic events recorded in a hard-rock mine were processed in order to study attenuation effects, source parameters and scaling laws for such events. Attenuation along the source-sensor path had a significant effect on the recorded signals. Quality factor of S waves (Qs) varied in the range 20-500, the peak being observed in the 50-150 range. The relationships between seismic moment and source radius on one hand and peak velocity parameter and seismic moment on the other were compatible with those expected from theoretical shear failure models. This strongly indicates a self-similar behavior of seismic sources.
