Huge diamond mines can create tornadoes that suck down helicopters

The world's most expensive Mir diamond mine in eastern Siberia can create a vortex strong enough to suck helicopters flying across the depths.

When On Earth, with a depth of 540m and a diameter of nearly 1.6 km, the pit near Mirny town in eastern Siberia looks like a meteor hit.Mir diamond mine is worth 17 billion USD, including the diamond that has been mined from the mine plus the remaining reserves.(Photo: Alrosa).

Although the opencast mine, which was located 8046 km east of Moscow, stopped operating in 2004, it was replaced by a series of underground tunnels that produced more than 6 million carats of rough diamonds in 2014. (Photo: Alrosa ).

The space above the mine was blocked by fears that the swirling gas caused by it could pull the helicopter down.However, no plane crash has been recorded here.Mir mine is owned by Alrosa in Russia, which produces about a quarter of the world's diamonds.(Photo: Alrosa).

In 2010, AB Elise, a construction company, announced plans to build a large domed city on an abandoned mine.The company said it would use solar energy to power 100,000 people.However, underground mining activities will have to be stopped before the plan becomes a reality.(Photo: Alrosa).

At the heyday, an average of two million carats of rough diamonds was declared differently from the Mir mine each year, worth at least $ 26 million.(Photo: Alrosa).

Olonkho is the largest diamond mined from Mir mine, weighing 130.85 carats, as big as a golf ball, worth about 323,000 USD.This mine was discovered in 1955 by three Soviet geologists, Ekaterina Elagina, Uri Khabardin and Viktor Avdeenko.(Photo: Alrosa).

Ore mine is located in the region with the harshest weather in the world.Winter can last 7 months and the temperature often drops to -40 degrees C, forming a thick layer of ice on the surface.Weather makes mining difficult.(Photo: Reddit).

When mining begins, miners use jet engines to create craters on permafrost, then use explosives to dig through the surface rock and disintegrate kimberlite ore.Three geologists were awarded the highest Lenin award by the Soviet government for their contributions.The Mir mine provided an important source of revenue for the Soviet Union to build and rebuild the country after World War II.(Photo: 56th Parallel).
