We can’t dig to the centre of the earth because the core of the earth is very very hot. Moreover, the earth is huge. The earth’s radius is 6,371 km. But scientists have tried to dig deep into the earth. Here are some of the deepest holes on earth.
1. Kola Superdeep Borehole, Russia
The Kola Superdeep Borehole is the result of a Soviet Union’s scientific drilling project. The Project began on 24th May 1949 using a drilling machine named Uralmash-4E and later the Uralmash-15000 series. They dug to the depth of 12,262 meters. It is the deepest artificial point on the earth, as of August 2019. The borehole has a 23-centimetre diameter.
2. The Bingham Canyon Mine
This mine is an open-pit mining operation extracting a large amount of porphyry copper deposit. The mine lies in the southwest of Salt Lake City, Utah, in the Oquirrh Mountains. This is the largest man-made mine in the world. It has produced the highest amount of copper compared to other mines in the world.
3. The Kimberley Diamond Mine
Also known as the big hole, Kimberley Diamond Mine lies in South-Africa. It is 700 feet deep and 1,519 feet across. It is the world’s largest diamond mine. The mine produced more than 6,000 pounds of the diamond before it closed in 1914.
4. Diavik Diamond Mine
The Diavik Diamond Mine lies in Canada’s remote Northwest territories. It is famous for diamond mining. The gross production of a diamond from this mine was 6-7 million carats. The white gem-quality diamond is mostly found in this mine.
5. IceCube Neutrino Observatory
It is located in Amundsen–Scott South Pole Station, Antarctica. The Ice Cube Neutrino Observatory (or simply Ice Cube) is a neutrino observatory. It is constructed at the Amundsen–Scott South Pole Station in Antarctica. Thousands of sensors are located under the Antarctic ice. The scientists have drilled a hole more than 8,000 feet deep for the construction of the observatory, which searches for subatomic particles called neutrinos. The answers collected from the research could shed new light on the nature of dark matter and other puzzling areas of physics.
