Abstract: This thesis observes both the evolution of the seismic response and associated seismic hazard at Goldex Mine’s D1-zone over the time period including August 2018 until December 2020. A variety of evaluation methods have been used to discuss the changes in seismic response, the source mechanisms, and the associated hazards. Data visualization and analysis were performed using mXrap software (Australian Centre for Geomechanics). Ultimately, the hazards of the change in seismic response are associated with significant or large seismic events occurring at times well outside of the normal blasting times. Understanding the role that both mining sequence and production constraints plays in the seismic response is key to understanding relative hazards. The change over time as the extraction ratio of the orebody increases is also considered.
