World’s Biggest Diamond Mine

Mar 18 2011

What a huge man–The mine is 525m (1,722ft) deep and has a diameter of 1,200m (3,900ft). This massive diamond mine is located in Mirna, Eastern Siberia, Russia.

The mine is so big that the airspace above the mine is closed for helicopters because of a few incidents in which they were sucked in by the downward air flow. To get a sense of perspective, check out the following photo to see the difference in size..

This giant truck, BELAZ (200-220 ton payload ) (see Figure 1), looks like small spot on next picture (see Figure 2). The truck in the picture, one of the biggest in the world, is just a small point in comparison to the diamond mine.

The town is strictly off limits to outsiders; without a special permit and the authorities regard any foreigners are supervised with considerable suspicion. A full report by the BBC. here.

History:

The mine 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 1940s and 1950s. 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 into permafrost, which was hard in 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. The winter temperatures were so low that car tires and steel would shatter and oil would freeze. During the winter, the workers used jet engines to defreeze and dig out the permafrost or blasted it with dynamite to get access to the underlying kimberlite. The entire mine had to be covered at night to prevent the machinery from freezing.
