The pearl giving mine in Russia is one of the biggest mines in world and is also known as world deepest pearl giving mine. The city situated around it is called”Diamond City”and the air egrets are so intense that a helicopter cant move around it.Otherwise it will engulfs the helicopter.
This mine have given stability to Russia after the second biggest world war.Firstly it was close from open side but now undergrounds tunnels have prepared for this purpose.

Mirny mine is a former open pit diamond mine located in Mirny, Eastern Siberia, Russia. This mine is 525 meters deep which made it 4th Deepest mine in the world with a diameter of 1,200 meter and is the second largest excavated hole in the world, after Bingham Canyon Mine. Now this Diamond mine is inactive, while it was operational it was taking two hours for trucks to drive from the top to the bottom of the mine.
The diamond-bearing deposit was discovered on June 13, 1955 by Soviet geologists Yuri Khabardin, Ekaterina Elagina and Viktor Avdeenko during the large Amakinsky Expedition in Yakut ASSR. They found traces of volcanic rock kimberlite which are usually associated with diamonds. This finding was the first success in the search for kimberlite in Russia, after numerous failed expeditions of the 1940 s and 1950 s. For this discovery, in 1957 Khabardin was given the Lenin Prize, which was one of the highest awards in the Soviet Union.
The development of the mine had started in 1957 in extremely harsh climate conditions. Seven months of winter per year froze the ground, which made it hard to mine in the winter, but turned into sludge in summer. Buildings had to be raised on piles, so that they would not sink in summer, and the main processing plant had to be built on a better ground found 20 km away from the mine.
