Location – BHPBilliton Nelson Point – Port Hedland. Plant – Stacker number 8. ‘A’ Area stockpile. This fire happened on March 6th. Initial assessment was that the fire was caused by hot work in the head chute, but the fire was caused by iron ore build up under the return side of the belt in launder catchment trays designed to direct the carry-back away from falling straight down.
Launder tray sprays can be ineffective if too much material hits the tray at once and as the clearance is not much, the catchment tray blocks up until material comes into contact with the moving belt.
