Bingham Canyon Copper Mine Highwall Failure

If you're part of the mining industry, then undoubtedly you've seen these photos this week. These photos are from Bingham Canyon mine, which is a major copper mine in the US, and represents about 6% of Rio Tinto's profit.

This wall failure had been predicted back in February, and there was no-one in the pit at the time of the incident. Estimates place the size of the failure at several tens of million cubic yards.

All photos by Ravell Call, Deseret News. For additional photos, see the link.

Stacker Fire

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.

Truck names

The blog had a comment this week:

their called haul trucks or (tonka trucks is a nickname we use).

A few people have commented on what I call the trucks. I call them rear dumpers to separate out what kind of haul trucks they are. Rear dumpers, belly dumpers, side tippers and moxys are all 'haul trucks', but are just individual types of haul trucks.
