|Mirny Diamond Mine|
The Mirny Diamond Mine is located in the city of Mirny, Russia. It is known as the world's largest mine, and also the world's largest man-made hole. It is 1,722 metetrs deep, so deep that all flight above it is forbidden as there have been too many helicopter crashes due to the hole's suction.
The diamond-bearing deposits were 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 the volcanic rock kimberlite, which is usually associated with diamonds. This finding was the second success in the search for kimberlite in Russia, after numerous failed expeditions of the 1940s and 1950s. (The first was Zarnitsa mine, 1954) For this discovery, in 1957 Khabardin was given the Lenin Prize, one of the highest awards in the Soviet Union.
