Kadykchan

Kadykchan (Russian: Кадыкчан) is an urban locality (an urban-type settlement) in Susumansky District of Magadan Oblast, Russia, located in the basin of the Ayan-Yuryakh River, 65 kilometers (40 mi) northwest of Susuman. Population: 0 (2010 Census preliminary results);^[1] 875 (2002 Census);^[2] 5,794 (1989 Census).^[3]

Its economy was based on coal-mining but it declined after the end of the Soviet Union.

Kadykchan (in Evenki language it means a small gorge, ravine) was built by the hands of GULAG's prisoners during World War II. Later it accommodated miners of a few local coal mines which supplied Arkagalinskaya electric power station. The depth of mines was about 400 meters (1,300 ft) what at some point along with the dropped demand for coal after the dissolution of the Soviet Union made the mining pointless. Moreover, there was an explosion at the mine when six people were killed in 1996, which lead to a decision to close the mines altogether. As of 2010, the settlement is completely depopulated.^[1]
