Probabilistic assessments utilise the statistics of past occurrences to attempt a forecast, with suitable confidence levels, of future occurrences in a given spatial volume and time frame. Purely deterministic methods use constitutive equations, equations of state, or equations of motion to extrapolate future behaviour. In this paper, we report on initial work towards deterministic assessments by compiling the statistics of the behaviour of physical variables based on seismic source parameters, and rock mass stress state and condition inferred from seismic velocities for comparison to the occurrence of significant events and/or damage at particular locations in mines. At this stage, we only report on whether patterns and statistics may exist.
