Speaking of the super drilling plan, it is necessary to have a certain amount of knowledge of the netizens have heard, like xiaobian such illiterates seem very strange, but after a general understanding of this plan, it happened that it stopped when it was dug to the 12262nd meter, so some people have to ask, why is this? Why is this happening? Say you've encountered a supernatural event? After all, is it hell? Let's analyze and reveal this problem together!
The title is Kola Chao
deep well! The Kola Ultra-Deep Well is a scientific drilling carried out by the former Soviet Union in the Kola Peninsula in 1970, and the deepest of which, SG-3, reached 12,263 meters in 1989, and to this day, at the depth of the perpendicularity, this drill hole is still the man-made object that reaches the deepest part of the earth.

The main purpose of this well is to conduct scientific research on the surface of the Moho surface. Of course, there are also reasons for the struggle for hegemony between the United States and the Soviet Union, and the United States and the Soviet Union have competed in many fields, hoping to overwhelm their opponents in all aspects.
The Moho interface is the sub-interface between the Earth's crust and mantle, which was discovered in 1909 by the Croatian seismologist Moholovic. He observed that seismic waves (especially P waves) suddenly increased in speed here. Earthquakes are the "B-ultrasound" that scientists understand the earth's interior, but the B-ultrasound is not directly seen clearly and directly.

Drilling began on May 24, 1970--- the 100th anniversary of Lenin's birth, and the first 7,000 meters went smoothly until beyond this depth, when a strato-type rock formation was encountered. Then there's the jam, where the drill drops when lifted. There have been several such accidents, each of which will cause great losses. In June 1979, the Soviets drilled the previous record of 9,583 meters held by the Berthar Rogers ultra-deep well in Oklahoma, USA, and the drilling was suspended at 12,066 meters in 1983. Drilling continued in 1984, and the first devolution had an accident – the drill string broke. Only to start from a depth of 7,000 meters, in 1990 the new side drill reached a depth of 12,262 meters, the drill string fell off again, and the drilling was forced to stop.
Then came the collapse of the Soviet Union, Russia's finances deteriorated, and there was no longer any money to start the project. In 2008 the well was abandoned, equipment was dismantled and ground buildings were damaged. In 2010, according to the assessment of the Dean of the Faculty of Geology of the Kola Science Center of the Russian Academy of Sciences, it would take one hundred million rubles to restore the project.
The Kola ultra-deep well is currently the deepest vertical depth, but its deepest well is not it. Its well depth records were broken in 2008 and 2011 by the Ashokhosin oil well in Qatar (12,289 meters) and the Russian OdoptuOP-11 oil well on Sakhalin Island (12,345 meters), currently ranking third in the world
