perm hazard map project
PERM: Hazard Map Project
  • MS density
    • Rock mass damage
  • Active planes
    • Presence of active MS planes
  • Seismic event magnitude
    • Peak particle velocity

Hazard Map Factors:

Outcome:

Operational real-time system at Creighton Mine

hazard map benefits
Hazard Map Benefits
  • Strategy
    • Hazard maps to track changing rock mass conditions
      • Location of critical infrastructure and future mine planning
      • Support upgrading and rehabilitation (where and when)
  • Safety
    • Enhance worker safety by identifying potentially hazardous areas
  • Operating Costs
    • Support upgrading and rehabilitation
    • Ore pass and ventilation raise location– hazard maps
    • Prevent production delays or ore sterilization
  • Training
    • Understanding mine specific problems and transferring knowledge
    • Reduce on-site training cycle for new personnel – 3D common earth model
  • Due diligence– State-of-the-art monitoring process
    • Seismic and MS data collection and evaluation

Partners

  • The research work would not have been possible without the support of the CVRD Inco Limited particularly the former INCO Technology Centre and Creighton Mine.
  • Special thanks are directed to:
    • Mr. Brian Maynard, Manager Creighton Mine
    • Mr. Farid Malek and Steve Audette, Creighton Mine ground control.
    • Mr. Denis O’Donnell and Dr. Denis Thibodeau, long-term ground control supporters.
  • Additional support was provided through the following agencies:
    • NOHFCO, CFI, OIT, OR&DCF
