385:, the largest diamond producing company in Russia, and employed 3,600 workers. It had long been anticipated that the recovery of diamonds by conventional surface mining would end. Therefore, in the 1970s, construction of a network of tunnels for underground diamond recovery began. By 1999, the project operated exclusively as an underground mine. In order to stabilize the abandoned surface main pit, its bottom was covered by a rubble layer 45 m (148 ft) thick. After underground operations began, the project had a mine life estimate of 27 years, based on a drilling exploration program to a depth of 1,220 m (4,000 ft). Production ceased in 2001, and the Mir mine closed in 2004.

The yield decreased to about 2 carats (0.40 g) per tonne and the production rate slowed to 2,000,000 carats (400 kg; 880 lb) per year near the pit bottom. The largest diamond of the mine was found on 23 December 1980; it weighed 342.5 carats (68.50 g) and was named "

The winter temperatures were so low that car tires and steel would shatter and oil would freeze. During the winter, workers used jet engines to thaw and dig out the permafrost or blasted it with dynamite to get access to the underlying

The development of the mine started in 1957, in extremely harsh climate conditions. Seven months of winter per year froze the ground, making it hard to mine. During the brief summer months, the ground turned to slush. Buildings had to be raised on piles, so that they would not sink from their warmth

In the 1960s, the mine was producing 10,000,000 carats (2,000 kg; 4,400 lb) of diamond per year, of which a relatively high fraction (20%) were of gem quality. The upper layers of the mine (down to 340 m (1,120 ft)) had very high diamond contents of four carats (0.80 g) per
