4 world's deepest artificial works

There are gigantic buildings that do not bring us close to the sky like the Egyptian pyramid or St. Peter's church but built in the exact opposite direction, which is digging underground.

Listed the deepest artificial works in the world

1. Ancient city of Derinkuyu

Talking about the complexity and beauty of architecture, we have to talk about the ancient city of Derinkuyu.

About 60 meters long in Turkey 's Cappadocia land, this labyrinth contains 20,000 citizens - including houses, wineries and schools.

Cappadocia is located in soft magma rock so it is possible that people here have dug underground caves as a residence right from 700 BC.

The underground city map consists of 5 floors, one at the end of each floor.(Photo: Supplied)

2. Kimberley Mine, South Africa

People have also dug deeper tunnels into the earth's crust, of course, much more effort. In the early 1870s and 1914, 50,000 workers in Kimberley, South Africa , screened 22 million tons of land while digging for diamonds.

Today it is known as "Big Hole ", the largest digging tunnel in the world.The mouth is 463 m wide, 240 m deep underground.(Photo: Richard L. Jones)

After the exploitation is completed, this huge deep pit has been filled with water and no different from natural lakes.(Photo source: Wikipedia)

3. Woodingdean well, England

Although smaller than the above excavations, Woodingdean well is near Brighton, England is the deepest artificial scar that cuts across the surface of the Earth.

It was 390 meters deep, equal to the height of the Empire State Tower , but less than a meter wide.

4. Mine of TauTona and Mponeng, South Africa

With today's development technology, we reach new depths. Along with giant machines powered by compressed air and electricity, the two mines of TauTona and Mponeng in South Africa broke the rock, down 4 km deep in the ground. It takes about an hour to take the elevator down to the bottom of the cellar, where the surrounding rocks have temperatures up to 59 degrees C. Therefore, a giant cooling plant is required to cool the tunnel air. The atmosphere below is hotter than anywhere on Earth.

Surprisingly, in high temperature conditions, low levels of oxygen in these attractive deep pools give people clues about extraterrestrial life , because the environment in other planets is similar. self like this.

We can search for objects from the vast universe out there in deep underground mines, because they have a separate environment, free from radiation.

Humans can trace fragile traces of dark matter - the mysterious form of matter believed to contribute to the mass of the universe.(Photo: New York Times)
