Purpose of Risk Based Design

  • Cater for the inherent variability in rock mass conditions
  • To address uncertainty
  • To apply engineering judgement
  • To enable decisions to made based on the level of risk to the operation
  • Risk = probability x consequence

Probabilistic vs Deterministic

  • Advantages of probabilistic analysis well known
  • Powerful methods of probabilistic analysis developed

Not widely applied in underground mining geotechnical applications

  • Additional effort
  • Acceptable probabilities of failure?
