TOP-10: The deepest places of the Earth
Now we approximately know the inner structure of our planet. The outer solid shell of the Earth is called the bark. It is less than 1% of the planet's mass and has a thickness of 5 to 70 kilometers. Next is the mantle (outer and inner), and then the core (outer and inner).
How close do you think the human being can fall to the core? Theoretically, we can in the future make devices capable of withstanding enormous loads and temperatures in order to get as close as possible to the core, but in practice we still have not got to the sites that are under the bark.
Let's see what the most The deepest places on the planet we know.

The depth of 370 meters
] This is a coal mine, which is located in Elsdorf in Germany. It is considered the deepest open mine in the world. Its depth is about 370 meters, and the area is about 33.9 square kilometers. Near the quarry is an artificial hill, which was formed from a material selected from the quarry.
The hill has its own name Sophienhöhe and is the world's largest artificial hill. Its height is 301 meters.

The Wellingdine Well
The Cave of Cruber
] The Kidd mine
Depth 3048 meters
The deepest mine in the world is the Mpongor mine in South Africa, its depth is 4000 meters, but the mine, called Kidd Mine in Ontario, Canada, which is 3048 meters deep, is closer to The core of the Earth, than the mine of the Hopper, because our planet does not have an ideal shape Due to the rotation of the Earth in the equatorial part, the diameter is slightly larger than at the poles, the difference being about 140 kilometers, so the person standing on the equator is removed an average of 70 kilometers from the core further than the person standing on the pole .
The Kidd mine was discovered in 1964 as an open cut and gradually expanded underground. Now it is the largest copper mine in the world. It employs 2,200 workers and produces millions of tons of ore per year.

The Challenger's Abyss
The depth of 10994 meters
The first five of the deepest sea depressions in the world include depressions located in the Pacific Ocean, and the most famous of them is the Mariana Trench, with a maximum depth of 10,994 meters (Challenger's Abyss).
The cavity originated from the Mariana Islands, finding The depression is 1500 km long, they have a standard V-shaped profile.The bottom of the hollow is flat, with a width of 1 to 5 km.
The water pressure at the bottom of the Challenger Abyss is 108600 Pa, this is 1100 times higher than the atmospheric Pressure on the surface of the Earth.The people twice sank to the bottom of the Mariana Trench. The first dive was carried out in 1960 by the researcher Jacques Picard and the US Navy, Don Walsh. Their bathyscaphe "Trieste" had a wall thickness of 127 millimeters to resist the monstrous pressure. The second time at the bottom of the hollow was the famous director James Cameron in 2012. He immersed himself in the Challenger's Abyss on a single-seater Deepsea Challenger deep-sea vehicle. During the dive, he took filming in 3D format.
The Kola Superdeep Borehole
The depth of 12262 meters
The length of the field of view of the Earth's surface,
This is the deepest man-made place on Earth, it is located in the Murmansk region near the city of Zapolyarny.
The work on the beginning of drilling was timed to coincide with the centenary of the birth of VI Lenin in 1970 In contrast to others, this well was drilled The site was chosen especially where the thickness of the earth's crust is supposedly the most thin.
Drilling was going on up to 7000 meters in normal mode, the drill passed through a uniform granite layer of the lithospheric plate. Less dense, crumbling, jammed equipment. It was necessary to change the angles of drilling a little.
After 13 years in 1983, drillers reached the level of 12066 meters and stopped. But after the resumption of drilling, there was a break in the drill string. Drilling had to start anew from a depth of 7000 meters. By 1990, the bury crossed the mark of 12262 meters and the accident was repeated. Then, for financial reasons, the project had to be frozen, and in 2008 the project "Kola Superdeep Well" was finally abandoned.
I really want to believe that Russian science will turn its face to this project. He has many perspectives. The lion's part of the work has already been accomplished, and in order to revive the project several million rubles are required, the amount of lifting is for a country with high scientific ambitions.
