The Biggest Holes Ever Made By Humans
7. Diavik Diamond Mine
This diamond mine, located in Canada’s remote Northwest Territories is actually a pretty recent hole! Work only began on this thing in 2003, and it is one of the world’s preeminent sources of gem diamonds. Since mining operations began, it has produced over 100 million carats of diamonds!!
6. Berkeley Pit
Located in Butte, Montana, this copper mine is now filled with heavily acidic water. Opened in 1955, this mine was used to get copper out of the Earth. Ironically it closed on Earth day in 1982. In the 80’s Berkeley Pit was 1700 feet deep and 900 feet wide. Approximately 320 million tons of ore and over 700 million tons of waste rock were mined from the pit.
5. Mir Mine
This is a diamond mine, and one of the largest excavations in history. This mine in Russia is the 2nd largest man made hole in the world. Located in outside of Mirny, a small town in Eastern Siberia, this place is 1,722 feet (525 meters) deep, and 3,900 feet (1.25 kilometers) across.
4. IceCube Neutrino Observatory
There are many different ways to make holes in the Earth as you know, or will soon learn. But for the University of Wisconsin, they wanted to do a study of the Earth from a different perspective. They decided to go to Antarctica and drill a massive hole into the very ice caps of the Earth to see what’s down there. Thus, the IceCube Neutrino Observatory was made.
3. Kimberley Diamond Mine
Also known as the Big Hole, the Kimberly diamond mine in South Africa, is home to the world’s largest diamond mine! It is so large it is visible by space and has produced some of the world’s largest diamonds.
2. Bingham County Mine
Also known as the Kennecott Copper Mine in Utah, this mine definitely takes the cake. This copper mine has been in use for over a century, and it’s still open to this day. It’s the biggest copper mine in the world and provides about 25% of the country’s copper needs.
1. Kola Superdeep Borehole
Have you ever wondered what’s at the center of the Earth? Fact is, no one really knows which is why the Kola Superdeep Borehole is so important. While the Bingham County Mine may be the largest manmade hole in the world, the Kola Superdeep Borehole is the deepest hole in the world!
