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
