Nearly 3 tons of diamonds have been dug up from one of the deepest holes in the planet!

Within 43 years, about 50,000 miners exploited 2.7 tons of diamonds in the Big Hole, South Africa.

From the deepest hole in the planet .

As of 2007, Kola Superdeep Borehole (Kola Superdeep Borehole) is the deepest point that people ever dig in the world. The deepest point at Kola Superdeep Borehole is 12,262 meters.

This was the result of nearly 19 years that Soviet scientists made in the underground underground exploration project launched by the Soviet government in 1962, deployed in 1970.

The expected depth that Soviet scientists plan to implement is 15,000 meters. However, due to technical limitations at that time, the hole stopped at a depth of 12,262 meters.

Later, from 2007 onwards, with advanced conditions of science, people continued to drill deeper boreholes to serve the demand of oil and mineral exploitation.

Here are the deepest artificial pits in the world, depending on the different uses of people (such as scientific research, exploration, exploitation .).

Big Hole is one of the deepest diamond mines in the world in the city of Kimberley (South Africa). By 1914, Big Hole was 214 meters deep and 463 meters wide.

Only in the period from July 1871 to 1914, about 50,000 miners dug more than 2.7 tons of diamonds in Big Hole.

Kennecott Copper Mine, the largest copper mine in the world - Kennecott Copper Mine

For over 100 years, Kennecott Copper is the largest copper mine in the world in the Oquirrh Mountains in the southwest of Salt Lake City, Utah, USA.

With the volume of 19 million tons of copper already exploited, the Kennecott Copper copper mine is considered the largest copper mining site in human history.

This copper mine began operating in 1906. The mine is 970 meters deep, 4,000 meters wide, covering an area of ​​770 hectares.

Observatory under the Antarctic ice - IceCube Neutrino

IceCube Neutrino Observatory is the first exploration project in the world designed to observe the universe from deep inside the Antarctic ice.

A total of 60 modules are "suspended" at depths from 1,400 meters to more than 2,400 meters below the cold ice in Antarctica.

This work was built by about 300 physicists from 12 countries in nearly 10 years.

Scientists hope, this observatory will help provide information to explore events such as exploding stars, gamma-ray bursts and cataclysmic phenomena involving black holes and neutron stars.

Sakhalin-I Odoptu OP-11 is the deepest well on the planet

After Kola Superdeep Borehole holds the record for the deepest artificial drilling hole on the planet by 2007, in August 2012, the Sakhalin-I oil well Odoptu OP-11 was dug out of the northern Sakhalin Island, by the Russian. The Pacific has set a new record at a depth of 12,376 meters.

To invest in this rig, Russia has spent billions of dollars to exploit crude oil and gas.
