Description
large dumptruck in utah copper mine

copper

* The giant electric shovels in the mine can scoop up as much as 98 tons in a single bite -- about the weight of 50 cars.
* The newest electric shovels each cost more than $20 million and weigh 3.2 million pounds.
* The trucks that haul the ore are larger than many houses and weigh more than a jumbo jet. They stand over 23 feet tall and can carry from 255 to 360 tons of rock.
* The truck driver rides about 18 feet above the ground -- nearly two stories high.
* Each tire on these big trucks costs from $18,000 to $26,000 and lasts just 9 months.
* The crusher in the pit takes in about 140,000 tons of ore every day and grinds it into chunks smaller than the size of a basketball.
* At 1,215 feet tall, the Kennecott smokestack is the highest structure in Utah.
