Yesterday we visited Kennecott Utah Copper Mine. It is the largest open pit mine in the world. I though some of you guys would appreciate the equipment they use to move the ore. They call these vehicles "Haulage Trucks". Their tires are 12.5' tall, and cost $25,000 per tire, which means 6 tires cost $150,000. The tires are replaced once per year on all 80 Haulage Trucks.....that is a lot of dinero. They can haul 320 tons of material at one time, and each of the 80 Haulage Trucks travels 50,000 miles per year within the confines of the mine hauling ore. They pretty much run 24/7, and move about 13 miles an hour.
