Hazard Map Factors: Hazard Map Factors:

• MS densityMS density– Rock mass damage

• Active planesActive planes– Presence of active MS planes

• Seismic event magnitudeSeismic event magnitude– Peak particle velocity

Hazard Map BenefitsHazard Map Benefits• StrategyStrategy

– Hazard maps to track changing rock mass conditions• Location of critical infrastructure and future mine planning• Support upgrading and rehabilitation (where and when)

• SafetySafety– Enhance worker safety by identifying potentially

hazardous areas

• Operating CostsOperating Costs– Support upgrading and rehabilitation– Ore pass and ventilation raise location – hazard maps

– Prevent production delays or ore sterilization

• TrainingTraining– Understanding mine specific problems and transferring

knowledge– Reduce on-site training cycle for new personnel – 3D

common earth model

• Due diligenceDue diligence – State-of-the-art monitoring process– Seismic and MS data collection and evaluation
