The long dark in Vorkuta. Part 3.

Vorkuta is a coal‑mining town situated in the northeast of European Russia, just north of the Arctic Circle. With its satellite towns, Vorkuta forms the so‑called Vorkuta Ring or Vorkuta Circle, which includes towns such as Severny, Tsementnozavodsky, Yur‑Shor, Promyshlenny, Vorgashor, Komsomolsky, Mulda, Zapolyarny, Oktyabrsky, Sovetsky and others. Their population was employed in coal mines and other industrial and military facilities. After the collapse of the Soviet Union, many mines were closed due to accidents and high operating costs, and people began to move to other regions. The towns of the Vorkuta ring became partially or completely abandoned, with some demolished. The Severnaya ("Northern") Mine was abandoned after a disaster that occurred in February 2016. A series of methane explosions at a depth of about 780 metres (2,560 ft) below ground caused the deaths of 36 miners and rescuers. The resulting underground fire was extinguished over 65 days by pumping water into the underground workings. The above‑ground part of the mine was mothballed and then dismantling began.
