What is the biggest mine in Norway?
Kongsberg Silver Mines
The silver mines of Kongsberg, in Buskerud county in Norway, constitute the largest mining field in Norway, with over 80 different mines. It was the largest pre-industrial working place in Norway, with over 4,000 workers at its peak in the 1770s and supplied over 10% of the gross national product of the Danish–Norwegian union during its 335-year-long history: over 450,000 man-years were expended in the production.
Store Norske Spitsbergen Kulkompani
The company has 360 employees and operates two coal mines. The largest one is located in the Sveagruva settlement, about 60 km south of Longyearbyen. The Svea Nord longwall mine has an annual output of 2 million tonnes of bituminous coal. A third of it is sold for metallurgical purposes. The managing director of Store Norske Spitsbergen Kulkompani is Per Andersson.
