Is the Russian Gate of Hell recording real?

Really, news and newspapers have confirmed that it is human beings exploring the unknown side of the underground world. Here is an introduction to this event:

1. The world’s deepest man-made drilling is located in Kola, northern Russia. peninsula. During the Cold War, the Soviet Union was determined to surpass the Americans in reaching the center of the earth and the moon. Excavation of the world's largest above-ground hole, the Kola Super Deep Drill, began in 1970 and was not completed until 1989. Legend has it that the Russians heard cries and screams from the boreholes and gave up drilling on the Kola Peninsula, fearing they had penetrated the surface and into the bowels of hell.

2. The Kola Super Deep Borehole was a scientific drilling project carried out by the Soviet Union in the Kola Peninsula near the Norwegian border in 1970. The deepest borehole reached 12,262 meters and remains the same to this day. World's deepest drilling record. One of the major discoveries in the Kola ultra-deep borehole was the massive hydrogen deposits, which were so large that the mud dug out of the hole "boiled" with the hydrogen deposits.

3. Theoretically, the process of drilling ultra-deep holes is very simple, just install such a rotary drilling rig at the bottom of a drill pipe. When it reaches the bottom of the hole, its powerful engine will drill through the bottom of the hole, so that the hole will continue to deepen. Fluid is constantly swirling in and out of the hole to cool the drill bit and maintain the stability of the hole. When a drill bit wears out, workers will replace it with another one.
