  1. Dozer Safety On Stockpiles

  2. Purpose • To increase the level of understanding around the risks associated with operating dozers on stockpiles with discharge feeders, and to share learning's and controls available to help minimise these risks.

  3. Outcome • Increased awareness around the operating risks • Share learning's from two recent incidents • Share some of the available controls to minimise these risks

  4. Stockpile and Feeder Design - Stockpile Cross Section Live Zone Dead Zone Conveyor Discharge Feeders

  5. Stockpile and Feeder Design - Stockpile Cross Section Live Area of Feeder Cones Live Zone Dead Zone Conveyor Discharge Feeders

  6. Principal Operating Risks and Hazards • Falling into feeder

  7. Principal Operating Risks and Hazards (cont.) • Domed out or rat holed feeder

  8. Principal Operating Risks and Hazards (cont.) • Slumping

  9. Principal Operating Risks and Hazards (cont.) • Engulfment

  10. Safety Statistics

  11. Dozer Incident – 19th March 2006 • 15:45 : Operator travels between feeder 7 and 8, Stops dozer due to limited visibility. After 3 to 5 minutes of being stopped, dozer falls into feeder cone. • 15:50: Emergency signal received, Dispatch unable to verify with TRD 326, Supervisor asked to investigate

  12. Dozer Incident – 19th March 2006 (cont.) • 16:00 : Supervisor unable to locate Dozer, decision is made to stop the systems ( trippers and feeders). • 16:10 : Mine rescue group informed. • 16:20 : Excavation commences on Feeder 1 • 18:00 : Upper Portion of Ripper exposed in Feeder 8

  13. Dozer Incident – 19th March 2006 (cont.) • 20:42 : The rear window of the bulldozer is cleaned by rescue teams, who discover by way of signals that the operator is alive. • 20:45 : Operator leaves the cabin of bulldozer 326 walking unaided.

  14. Dozer Incident – 19th March 2006 (cont.) • Cabin of dozer where operator was trapped, it is believed that the air conditioning fan continued to circulate air from engine bay through cabin throughout event • Operator remained calm throughout event • No additional oxygen supplies used, • Recovered dozer

  15. Learnings From These Events • Comunication/Emergency • system needs to work in all conditions • Operators need to be able to understand the risk in order to control it • Challenge our operations to rigorously apply the hierarchy of controls

  16. Hierarchy of Controls • Eliminate– Dozerless stockpiles • Separate – Remote Control Dozers • Re-design – Stacker/Reclaimer systems, Load out bins • Substitution – Low profile blades to improve visibility, Establish stockpile trigger points. Eg. >400Kt – Isolate feeders/trippers before pushing in • Administration – training to increase awareness, GPS to locate feeders, Feeder indicating lights • PPE – Oxygen in cabins, self rescuers, Strengthened glass, ROPS,
