The Kiruna mine is the largest and most modern underground iron ore mine in the world. The mine is located in Kiruna in Norrbotten County, Lapland, Sweden. The mine which is owned by Luossavaara-Kiirunavaara AB (LKAB), a large Swedish mining company, has an annual production capacity of over 26 million tonnes of iron ore. In 2008 the mine produced 27.5 million tonnes of iron ore. The Kiruna mine has an ore body which is 4 kilometres (2.5 mi) long, 80 metres (260 ft) to 120 metres (390 ft) thick and reaching a depth of up to 2 kilometres (1.2 mi). Since mining began at the site in 1898, the mine has produced over 950 million tonnes of ore.
In 2004, it was decided that the present centre of the municipality would have to be relocated to counter mining-related subsidence. The relocation will be made gradually over decades.
