Abstract:
In deep and high stress mining environments, blasting routinely induces and triggers dynamic rock mass failure. This complex interdependence is challenging to understand, particularly using traditional seismic source parameters and techniques adapted from earthquake seismology. Distance time (DT) parameters are mining specific, designed to quantitatively differentiate between Type A (induced) and Type B (triggered) seismic events in mines. Isolating triggered from induced events enables early and reliable identification of high-risk (Type B) mechanisms throughout the rock mass, a critical component in the development of effective and comprehensive seismic risk management plans. Data from Vale’s Coleman Mine demonstrates how these parameters can be used to evaluate seismic source mechanisms, improve or independently corroborate traditional analysis results, and produce novel seismic source mechanism and risk maps.

Keywords: mine seismicity, seismic analysis, seismic source mechanism, seismic risk
