The propagation of Seismic Waves in a Deep Mine

In mine environments modeling of elastic seismic wavefields require detailed 3D petrophysical, infrastructure and topographical data to simulate the propagation of seismic wave with a frequencies up to few kilohertz. For engineering purposes, amplitudes and travel times of seismic events are critical parameters that have to be determined at various locations in a mine. These parameters are useful in preparing risk maps or to better understand the process of spatial and temporal stress distributions in a mine. In this talk, the effects of strong elastic contrasts on the propagation of seismic waves will be illustrated using 2D/3D finite difference method.
