The Kiruna mine is the largest and most modern underground iron ore mine in the world.[1][unreliable source?] The mine is located in Kiruna in Norrbotten County, Lapland, Sweden.[1] The mine is owned by Luossavaara-Kiirunavaara AB (LKAB), a large Swedish mining company. In 2018 the mine produced 26.9 million tonnes of iron ore.[2] The Kiruna mine has an ore body which is 4 km (2.5 mi) long, 80 metres (260 ft) to 120 metres (390 ft) thick and reaching a depth of up to 2 km (1.2 mi). Since mining began at the site in 1898, the mine has produced over 950 million tonnes of ore.[1] As of 2020, the main haulage level is 1,365 m below the ore outcrop at Kiirunavaara that existed prior to mining.[3]

In 2004, it was decided that the present centre of the city would need to be relocated to accommodate mining-related subsidence. The relocation would be made gradually over decades.[4]
On May 18, 2020 an earthquake of approximate 4.9 Mw was triggered in the footwall of the mine.[5] The earthquake was not natural but induced by the mining activity.[5]
