The Kola Superdeep Borehole in Russia is the world's deepest hole dug by man. Here are some interesting facts compiled by us from various sources:
1. Kola Superdeep Borehole is located in Russia. This hole was dug during the Soviet Union in the name of science, so scientists could find out what was down there. Unmitigated, he plunged as far as 12 kilometers underground, deeper than the Mariana Trench. If people drop, it takes about 3.5 minutes to reach the bottom.
2. This hole was dug by Soviet Union scientists, when it was still during the Cold War. In addition to the race to space, superpower countries also seem to be competing to dig into the depths of the Earth, there is even an ambition to reach the core layer of planet Earth. Apart from the Soviet Union, the United States and Germany also have excavation projects
3. The world's deepest pit project began in the 1970s in the Murmanks region of the Arctic circle. For about 20 years, they managed to reach the depths of the Earth up to 12 kilometers.
4. The US was the first to dig in the late 1950s. The American Miscellaneous Society organization launched Project Moonhole. But they are not digging in the ground, but under the Pacific Ocean in Guadalupe, Mexico. In 1990, the German Continental Deep Drilling Program (KTB) was started in Germany, which succeeded in digging up to 9 kilometers underground.
5. Digging the world's deepest hole was not in vain. Found water at that depth which was previously thought to be impossible. About 7 kilometers below, there are microscopic fossils of 24 species. They also accessed ancient rocks about 2.7 billion years old.
6. For about 20 years, Soviet scientists managed to reach the depths of the Earth up to 12 kilometers which has not been defeated until now. The drilling machine used by the Soviet Union was called the Uralmash-4E and the next generation, the Uralmash-15000.
7. Excavations were stopped in 1992 when the temperature down there reached 180 degrees Celsius so that the drilling tools could no longer function.
8. With the collapse of the Soviet Union, no more money was spent on such a project, so three years later or in 1995, all facilities were closed.
9. Initially, the excavation target of the Kola Superdeep Boregole was 15 kilometers deep which was predicted to be completed in 1993, but it was not successful.
10. Now, the Kola Superdeep Borehole, which has a diameter of 23 cm and is covered with metal, is only a tourist destination, among the facilities that have been damaged. Nevertheless, his role in science is still remembered.
