Original title: When the Soviet Union dug through the earth, why did it stop digging to 12265 meters? 50 years later, the truth comes to light. Earth It is the mother of human civilization. Since the birth of human beings, the earth has silently provided shelter, water and food under the feet of human beings. Until now, Mankind has a history of three million years. Today, human beings can go to space to land on the moon and go down to a 10,000-meter-deep trench for scientific research, thus realizing the desire of "going up to the sky and down to the sea". But,dth drilling hammer, Even though human technology is very advanced, Knowledge of the Earth beneath our feet is still scarce. During the Cold War between the United States and the Soviet Union in the last century, the two superpowers competed in various fields, including scientific and technological exploration. Among,dth hammer bit, America To study the secrets of the depths of the earth, Undertook a plan that sounds incredible: Dig through the earth! Soviet Union After learning about it, The same plan was carried out, And in When the United States could not dig to 500 meters, the Soviet Union dug to a depth of more than 10,000 meters. But what makes later generations wonder is why the Soviet Union dug through the earth. Expand the full text 12265 rice Just stop? The truth about the plan did not come to light until 50 years later. Excessive input In fact, the original idea of the Soviet Union to set up this plan is the same as other "arms race" projects, mining drill bit ,mining dth bit, except that In order to surpass the United States in a certain field and prove the superiority of its own system. Therefore, although we know that a project that simply "digs holes" is likely to have no return. The Soviets decided to try, at least to dig deeper than the Americans. At that time The Soviet Union's excavation plan was chosen The Kola Peninsula, This place Located in the northwestern tip of Russia, most of its area is within the Arctic Circle. But in order to make the technicians feel at ease to stay here and "dig holes", the Soviet Union arranged very generous benefits for the project personnel, each of whom had a villa in the Black Sea Resort, and also delivered a large number of supplies on time. Encouraged by this policy, the progress of the project is indeed very fast, and more than 10,000 meters have been dug in just a few years. Can't see the return But, When the Soviet Union dug more than 10000 meters, the excavation work encountered difficulties: The tunnel here is already a high temperature environment deep in the earth. The drill bit of the drilling rig will burn down in a few minutes. If we continue to dig, the cost will be higher and higher. But what is the actual value of this project? No one can answer. Because The cost of the project is so high that these excellent technicians only need to dig holes. Actually, also It is a waste. After consideration, therefore, The relevant leaders of the Soviet Union stopped the digging project. The Soviet record for digging a hole was only 12265 meters. Mysterious legend After the Soviet Union ended the project, there were many mysterious legends: Some people say that the Soviet Union stopped digging because it heard "voices from hell". This statement has aroused the interest of a large number of people, and they are very curious about what the Soviet Union's project has achieved. Is there really a "hell" in the depths of the earth that modern science does not know? However, according to the former Soviet documents disclosed by Russia 50 years later, The idea of "hell" is just an urban legend. The truth is, Soviet technicians did hear mysterious sounds from the depths of the earth. But it was later found out that It's just the wind from an underground cave somewhere in the tunnel. However, human exploration of the earth will never stop here, and people will inevitably use more advanced technology to explore the earth under their feet in the future. To understand the earth is actually to understand human beings themselves.
