Abstract

Seismically active geologic faults are the source of high hazards in mines, with the potential to generate very large and unexpected seismic events with extensive damage and production loss.
Several methods have been implemented to assess the seismic potential of faults. However, most methods only consider homogeneous fault planes, which leads to a unique value for hazard estimation and failure to consider the existing fault plane heterogeneities and the stochastic nature of seismicity.
This thesis develops a method to explicitly account for heterogeneities of modelled faults, generating a stochastic estimation of fault seismic potential when affected by mine induced stresses.
