In Soviet times in the territory of our countryA sufficient number of cities have been built, many of which are real ones in terms of their geographic location and engineering solutions used. This is the city of Mirny (Yakutia). The quarry for diamond mining, which is located in its line, is one of the wonders of the modern world, since it amazes even the most experienced specialists with its size.
The name of this substance came fromSouth African city of Kimberley. There, in 1871, a diamond weighing almost 17 grams was found, and as a result, prospectors and adventurers from all over the world poured into that region with an uncontrollable stream. How did our city of Mirny (Yakutia) come into being? Career is the basis of his appearance.
In Moscow, the codedThe radiogram: "Have smoked a tube of the world, an excellent tobacco"! Only a few days later, huge columns of construction equipment were pulled into the wilderness. That's how the city of Mirny (Yakutia) emerged. The quarry had to be developed under extremely difficult conditions. One has only to look at the excavation covered with snow, in order to understand the grandiose scope of the works carried out here!
To break through a few meterspermafrost, it was necessary to use tens of thousands of tons of powerful explosives. Already from the 60s of the last century the deposit began to give stable two kilograms of diamonds, at least 1/5 of them were of excellent quality and could be shipped to jewelry stores after cutting. The remaining stones were intensively used in Soviet industry.
The government of the USSR agreed, but demandedresponse service - to allow deposits in South Africa to let Soviet specialists. A delegation from Africa arrived in Moscow ... and there it was delayed, because the guests were constantly hosting banquets. When the experts finally arrived in the city of Mirny, they had no more than 20 minutes to inspect the quarry itself.
But what they saw all the same struck to the depthssoul. For example, guests simply could not imagine the technology of mining diamonds without using water. However, there is nothing surprising in the Yakut climate conditions for this: in those places almost seven months of the year there is a subzero temperature, and it is not worthwhile joking with permafrost. In a dangerous place is the city of Mirny! The depth of the quarry is such that, if desired, even a miniature sea can be built here.
Helicopters fly over the open pit categoricallyIt is forbidden, since such a flight is a sure death for the car and the crew. The laws of physics simply throw the helicopter to the bottom of the quarry. The high walls of the tube also have shortcomings: there is not a phantom possibility that once precipitation and erosion lead to the formation of a monstrous landslide, which will completely swallow the city of Mirny (Yakutia). A quarry, the photo of which is in the article, can be used for purposes that some may find real fiction. We are talking about the possibility of creating in a titanic pit a unique city of the future.
The head of this project was appointed NicholasLyutomsky. The most difficult thing in the future work is to create a cyclopean concrete structure, which will not only strengthen the quarry walls, but will also propel it, providing additional strength. It will be an incredible tourist attraction, which can only boast the city of Mirny!
The fact is that this area is cooled in winterup to -60 degrees Celsius. Yeah, it's hard to envy those for whom the city of Mirny (Yakutia) is the motherland. The quarry, whose photo is striking, is similarly imaged, but only to a depth of 150 meters. Below - constantly positive temperature. Futuristic city is supposed to be divided into three main tiers. At the bottom, they want to grow agricultural products, on the average it is planned to mark out a full-fledged forest park zone.
The upper part is a zone for permanent residencepeople, in addition to living quarters, there will be offices, entertainment complexes and so on. If the construction plan is fully implemented, then the area of the city will be three million "squares". At the same time, up to 10 thousand people can live here. About 36 thousand citizens have a peaceful city (Yakutia). Quarry, whose depth is half a kilometer, will allow them to rest comfortably, without flying for this to distant lands.
For the lower levels to receive enough light, incenter it is supposed to leave a lighting shaft of giant diameter. In addition to solar panels, the efficiency of which is still rather doubtful (plus the difficulties with installation), some engineers propose a variant with the construction of a nuclear power plant. To date, all this is in the stage of very vague plans. I'd like to hope that the city of Mirny, whose diamond quarry is known all over the world, will become more comfortable for people living in it.
As we said, in the 60's for the year hereUp to two kilograms of diamonds were mined, and a fifth of them were of high quality. A ton of rock accounted for a gram of pure raw materials, and among the stones there were many such that were suitable for jewelry processing. Today, a ton of ore accounts for approximately 0.4 grams of diamonds.
In late December 1980, the largest diamond in the history of the deposit was found here. This giant, weighed 68 grams, received the solemn title "XXVI Congress of the CPSU."
When did Mirny "finish off"?Diamond quarry became dangerous to develop in the 1990s, when the depth of development reached 525 meters. At the same time, the bottom of the foundation pit was flooded. It was Mir that became the largest diamond quarry in our country. The extraction lasted more than 44 years. Until then, the extraction was led by the Sakha company, whose annual profit exceeded $ 600 million. Today, the mine is managed by Alrosa. This corporation is one of the largest diamond producers in the world.
Here is the raw material rich in the Republic of Yakutia:Peaceful career in which shakes the imagination of everyone is one of the sources of national wealth. The diamonds that are mined there go not only for the needs of jewelry companies, but also for the production of a multitude of complex instruments and mechanisms.
