 Since the resettlement of Spitsbergen in the early 20th century, coal mining has been the dominant commercial activity.Store Norske Spitsbergen Kulkompani, a subsidiary of the Norwegian Ministry of Trade and Industry, operates Svea Nord in Sveagruva and Mine 7 in Longyearbyen.The former produced 3.4 million tonnes in 2008, while the latter sends 35% of its output to Longyearbyen Power Station.
