Mir Mine additionally referred to as Mirny Mine is a former open pit diamond mine situated in Mirny, Japanese Siberia, Russia. On the time of its closing in 2004, the mine was 525 meters deep and 1,200 meters throughout making it the second largest excavated gap on the planet, after Bingham Canyon Mine. The opening is so massive that airspace above the mine is closed for helicopters due to incidents wherein they had been sucked in by the downward air movement.
Mining started on 1957, in extraordinarily harsh local weather circumstances. The Siberian winter lasted seven months which froze the bottom, making it arduous to mine. Throughout the temporary summer time months, permafrost would develop into mud turning the complete mining operation right into a land of sludge. Buildings needed to be raised on piles, in order that they'd not sink. The primary processing plant needed to be constructed on higher floor, discovered 20 km away from the mine. The winter temperatures had been so low that automotive tires and metal would shatter and oil would freeze. In the course of the winter, staff used jet engines to burn via the layer of permafrost or blasted it with dynamite to get entry to the underlying kimberlite. Your complete mine needed to be lined at evening to forestall the equipment from freezing.
Throughout its peak years of operation, the mine produced 10 million carats of diamond per 12 months, of which a comparatively excessive fraction (20%) had been of gem high quality. This frightened De Beers firm, which at the moment was distributing many of the world's diamonds. The corporate was compelled to purchase bigger and bigger shipments of excessive-high quality Russian diamonds so as to management the market worth. For De Beers, Mir was a puzzling thriller. The mine’s monumental output was not in step with the comparatively small measurement of the mine. By the Nineteen Seventies, when the Mir ought to have been producing smaller and smaller portions of diamonds, the Soviets have been producing an rising amount of gem diamonds. Lastly, in 1976, De Beers requested a tour of the Mir mine to fulfill their curiosity. Permission was granted, however the Russians saved delaying the go to and by the point the staff of delegates reached the Mir mine, their visas had been about to run out, in order that they might solely have 20 minutes on the Mir mine. The go to did little to make clear the thriller of the Mir’s diamond manufacturing.
After the collapse of the us, within the Nineties, the mine was operated by a couple of native firms till 2004 when the mine was completely closed.
