The deepest hole in the Earth: digging for 24 consecutive years 12km, and more than 6300km to reach the center of the Earth

At that depth, the rock which was hardened had the same characteristics . like plastic.

In western Russia, there is a rusty metal piece lying on the ground. Few people know that this is the lid of the world's deepest artificial pit. The Russians sealed this cover to the ground, locked a pipe 12 km deep into the world with the world.

Kola Superdeep Borehole - Kola Superdeep Borehole.

Specifically, how deep is 12km? It is deeper than the deepest point in the ocean, and is the deepest hole one has ever measured. Its name is Kola Superdeep Borehole , and it is dug for scientific purposes. No deep "plot" below this hole!

The study area is now abandoned.

When scientists from the Soviet Union dug this hole in 1970, they planned to learn about the components that make up the Earth's crust."Because there is a fact, we know less about what lies below our feet than on the other side of the Solar System," Hanh Green, the YouTube SciShow host, said of the Super Deep Hole digging project. of Russia.

The Russian stamp bears the shape of Kola.

For 24 years, scientists have tried to dig as deep as possible, but in 1994 (the time the project stopped), they only dug 12,262 meters, equivalent to 0.2% of the distance to the center. Earth. However, this is still the deepest pit record that people have ever dug.

To dig, they invented a special drill that only rotated at the drill bit, had a lubricant pipeline, a high-pressure mud to make the drilling more smooth. And when drilling that hole, scientists have also invented new tools to be able to research and exploit information from the deep excavated hole.

Drill bits are used.

Under the utmost depth, they found the whole country! Different from the kind of water we have on the surface of the Earth, this water comes from oxygen and hydrogen that is squeezed out of the minerals below, because of the enormous pressure in the Earth's interior. extremely small of 24 extinct single-celled living creatures.

12km is very deep, but we still can't go through the Earth's crust.

When they reached a depth of 12km, they reached the stone with a life of 2.7 billion years. But also at that depth, the temperature reached 180 degrees Celsius, making further drilling impossible. The project had to stop. Researchers describe rocks at this depth that resemble plastic, but not the usual rock on the surface.

12km is very deep, but we still can't go through the Earth's crust! The mantle (mantle) part starts from a depth of 35km. But 12km is indeed very impressive compared to the technology of 1994. Surely in the near future, we will go deeper!
