3.2 Characterization of the Malmberget Mine. In the Malmberget Mine, many studies have been carried out aimed at characterizing the rock mass [3, 4]. Debras [3] tried to characterize the rock mass hosting the Printzsköld orebody, and offered a comprehensive petrologic and geologic description. Wänstedt, [4]

The Malmberget mine (Swedish: Malmbergsgruvan) is one of the largest iron ore mines in Sweden. The mine is located in Malmberget in Norrbotten County, Lapland. The mine which is owned by Luossavaara-Kiirunavaara AB (LKAB) has an annual production capacity of over 5 million tonnes of iron ore.

The mine comprises a total of 20 orebodies of which about 10 are in active production today. The mine is located in the municipality of Gällivare; see Figure 1 (Martinsson and Hansson 2004). Over the years, extraction from these orebodies has created varying subsidence problems Malmberget has a long and shared history with nearby Gällivare. The first mining for iron took place in 1735 and the area has since been heavily connected with the iron mines.

Malmberget mine

The mine which is owned by Luossavaara-Kiirunavaara AB (LKAB) has an annual production capacity of over 5 million tonnes of iron ore. LKAB’s Malmberget (ore mountain) iron ore mine, located at Gällivare, 75km from Kiruna, contains 20 orebodies spread over an underground area of about 5 by 2.5km, of which 10 orebodies are currently being mined. Mining began in 1892 and since then over 350Mt of ore have been won. Every day, 365 days a year, iron ore equivalent to around six Eiffel Towers (in terms of the amount of steel) is mined in LKAB's mines. The mining takes place in the underground mines in Kiruna and Malmberget, and at the Gruvberget and Leveäniemi surface mines in Svappavaara.

Today’s mining is between 800 and 1200-m depth and distributed over an area approximately 2.5 km × 5 km in size (NS × EW). Malmberget, you see, is being swallowed by a giant crater. As the mining industry grows, an ever-widening pit some three miles deep and almost half a mile across metastasizes across the landscape. The ground is literally crumbling under Malmberget. Viewed from Google Earth, the dark pit that is the mine resembles a massive lake.
