Långban Mine
Mine workings reached depths of up to about 365 m. Exploration divers have reached about 160 m; regular dive levels are at about 21, 40, 55, 75 and 90 m. NGDF gives the mine as about 370 m deep and explored to 100-115 m (undated).
Historic mine workings at Långban in Värmland, flooded since closure in 1972 and dived since 2005 by a members-only club working with the Värmland Museum. Dive levels run from about 21 m to 90 m in cold, very clear water.
Långban in Filipstad municipality was mined from the 16th century, commercially from the mid-17th century, until it closed in 1972. When the pumps stopped, the workings flooded from surrounding lakes. Shafts reached as deep as about 365 m once dynamite came into use.
Diving began in 2005, when divers and the Värmland Museum together founded Långbans Dyksällskap (the Långban Diving Society). Divers originally entered through Storgruvan; the entry now is a purpose-built platform in Kollegiegruvan with benches, lighting and a whiteboard for dive plans, plus small underwater habitats at shallow stops.
The club has about 100 active members logging roughly 1,500 dives a year. Dive levels lie at about 21, 40, 55, 75 and 90 m, and exploration teams have reached about 160 m in the Loka shaft. Project divers keep the mine maps updated and document new sections with 3D photogrammetry.
