Hole 12km deep underground in Russia: mysterious rumors about the road “to hell”

0  comments

Dubbed the “Hell’s Well,” it has long been abandoned, yet remains the deepest hole in the world and is known for its mysterious rumors and myths.

Like every other mysterious site, the Kola borehole (12,226 km deep and 23 cm wide) has a terrifying legend, dubbed the “Well of Hell”.

According to this legend, when the drill reached a depth of 12km, the researchers discovered a temperature above 1,000 degrees Celsius.

The researchers then put down a heat-resistant microphone and recorded the alleged screams of the tortured down there. For this reason, it was rumored that the drill touched “Hell”.

Of course, the aforementioned story quickly proved dumb. Because no microphone can withstand the temperature of 1,000 degrees Celsius. Along with that, the drilling has stopped at a depth of 12,262 meters, say the temperature is only about 200 degrees Celsius.

Despite this, David Guberman, the head of the drilling facility, admitted there was a bizarre incident at this site in 1995.

Why was it created?

The Kola borehole is located on the Kola peninsula, in the Murmansk region of Russia. This hole was created as part of the USSR Superdeep Bored Project. Twelve such super-deep drilled holes have been drilled, including Ural Superdeep (6 km) and Yen-Yakhin (8.25 km).

The aim of the project is to examine the Earth’s crust in undiscovered depths. Unlike other boreholes, drilled to search for oil or gas fields, the Kola hole was created purely for a scientific purpose: to study the inner composition of the Earth’s crust.

Drilling continued from 1978 to 1992. The drilling site was meticulously selected by scientists. The Kola peninsula is the upper part of the Baltic shield – a giant crust of granite and minerals that erupted from below about 3 billion years ago.

This is one of the oldest shields on Earth. That’s why research is so important (and revolutionary).

Down to the center of the Earth

The drill hole divided into many branches when deep below the Earth.

During the first four years, everything went smoothly, with the drill reaching a depth of 7 km. Then, an additional drill was installed with the final drilling device weighing 200 tons.

From the original drill hole, more drilled holes were drilled apart and the drilled lines began to curve more, because the drill had to go around the hard bedrock.

By 1983, the depth had exceeded 12 km, but in 1984, an incident happened – the spindle was broken and the drilling had to be restarted from 7,000m again.

By 1990, the depth had reached 12,262m, but the drill broke again – and this was the last time. After that, the drilling into the Earth’s center stopped. Since then, the Kola drill hole is still the deepest hole in the world.

In 1995, five years after the drilling stopped, an unknown explosion occurred here. David Guberman even said he couldn’t understand what happened. The drill hole has become a mystery later on.

Meanwhile, research on the Kola bore has reversed all previous conceptions about the composition of the Earth’s crust. It has contributed significantly to the study of the Moho disruption zone – the boundary between the Earth’s crust and the mantle.

However, the Kola study doesn’t yield any readily available answers – it just raises more questions. The most obvious finding was that below 4 km, the temperature began to rise dramatically, reaching more than 220 C at a depth of 12 km.

Currently, the facility where the Kola borehole is located is abandoned and dismantled by the locals. The 23 cm wide bore is now sealed with a metal cap, while the Kola borehole science dissolves in 2008.
