## Economy

The Mir mine is located within the town. It is an open pit mine, which, with the depth of 525 meters (1,722 ft) and a diameter of 1.25 kilometers (0.78 mi) is reckoned to be the second largest in the world. Production was stopped in 2004, and the mine was permanently closed in 2011, due to reduced recovery and the costs of working in the far northern climate.

### Transportation

The town is served by the Mirny Airport. Safety concerns have been raised about aircraft operations near to the open diamond mine; helicopters are forbidden to pass over the abandoned workings.

## Education

The Mirny Polytechnic Institute, a branch of the North-Eastern Federal University, operates in the town.
