Deepest Open-Pit Mine In The World - The Bingham Canyon Mine
Published June 22, 2016
No pit is deeper than the Bingham Canyon Mine, also known as the Kennecott Copper Mine.The copper mine in Utah, USA, was opened in 1906 and has been in production ever since. The mine is an open-pit mine, which means it consists of an open hole in the ground instead of underground tunnels. And with 1,2 km (3,900 ft) to the bottom, it is the deepest open-pit mine in the world. The mine got a bit shallower in 2013 when 65-70 million m3 (2.3-2.5 billion ft3) of soil and rocks came loose from one side of the mine and slid to the bottom (the largest non-volcanic landslide ever recorded in North America). Thanks to warning signals from a safety system, no one was injured. The two bottom photos show Bingham Canyon Mine before and after the slide.
