Tallest elevator in a mine

The world's tallest elevator in a mine shaft is at AngloGold Ashanti's Mponeng Gold Mine in South Africa, which in three minutes drops an astonishing 2,283 m (7,490 ft) in a single descent – more than 4.5 times further than those in the world's tallest building, the Burj Khalifa. A second elevator then takes miners even lower, to 3,597 m (11,800 ft). Each day the lift ferries 4,000 workers down to the mine – 120 workers at a time in three-level steel cages, at speeds of up to 40 mph. It first operated in 1986.
