LKAB last reported a seismic event occurred at Kiruna on April 19, saying its preliminary magnitude was 1.77 according to the local scale. Kiruna's ore is mined at a depth of more than 1,000m and The seismic event occurred at 3.11 a.m.

In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests.

Criteria were developed (Table 2) during the study to select suitable seismic events out of 46 already studied seismic events having occurred in block 33/34 of the LKAB Kiirunavaara Mine between 2008 and 2013 (Nordström et al. 2017) for further back analysis to evaluate the performance merits of the short-term seismic hazard parameters (indicators) used in mines and their potential seismic source parameters from the LKAB database.

LKAB constantly monitors seismic activity. It does this with hundreds of instruments called geophones that detect shock waves in the bedrock. Using their readings, both the strength and exact location of an event can be calculated. This is the reason LKAB does not measure event magnitude on the Richter Scale but uses a local scale.

Brief information via sms and e-mail is forwarded to the responsible and affected individuals internally within LKAB and externally to for example the municipality and the County Administrative Board. LKAB constantly monitors seismic activity.

On 17 May 2020, the LKAB Kiruna Mine experienced a seismic event that resulted in a significant fall of ground, deep within the site. The mine was immediately closed and mine managers began determining how best to assess the damage.

“Bio-oil is an important step in the transformation process for a fossil-free future, even though LKAB’s goal is to transition to entirely carbon-free alternatives in the longer term. We are pleased to have in place the first iron ore products produced using entirely fossil-free fuel, which can then be processed further into steel,” says Christian Fredriksson, a specialist in combustion. 2021-04-19 · In 2020, LKAB hauled over 34 million t on the Ore Railway, mainly iron ore from the mines in the orefields, to the ports in Luleå and Narvik for onward shipment to customers. The mining company now wishes to increase production further and, with such great volumes, even a few percentage points in capacity increase can have a significant impact.

Please check out our events overview for the latest updates. Join us for our next event! As LKAB’s underground iron ore mines get ever deeper, seismic activity is increasing. This is managed with considerable technical effort, well-developed procedures and an increasingly safety-aware staff. Consequently, the number of accidents has also decreased in recent years. LKAB’s vision for the systematic safety work is no accidents.
