EXAMENSARBETE - DiVA

2020-12-21 Now, just over a month after the biggest seismic event ever registered by LKAB, the investigation has come a long way. In addition to accounting for the causes of the event, the investigation will also provide a basis for future decisions as to, for example, the layout of the mine, i.e., how roads and production areas will be located with respect to factors such as seismicity. Although LKAB has a very delicate system for measuring rock movements, it is impossible for the mining company to predict quakes. - We had no warning about this and it is not possible to say when a seismic event will take place, says Fredrik Björkenwall, acting press officer at LKAB. LKAB KIRUNA SEISMIC EVENT INSPECTIONS AMKVO conducted over 30 flight and walking scans, at a depth of 1,236 meters below the surface, to map the damage throughout kilometers of drifts in Kiruna. “We were able to scan much faster than LKAB expected.

Join us here for tips on training, preparing for events and reviews of kit and food. When a seismic event has occurred and has been registered by the LKAB seismic system a mining engineer firstly completes a preliminary analysis of the event.

2021-01-20 · Seismic events are occurrences in which energy is briefly released in the Earth's crust, resulting in a series of seismic waves which move through the crust. In some cases, the energy can be intense enough that it is felt in the form of an earthquake, while in other seismic events, the energy is so mild that it can only be identified with specialized equipment. LKAB has around 4,000 employees, of which more than 600 are outside of Sweden. There are iron ore mines, processing plants and ore harbors in northern Sweden and Norway, and sales office in Germany. LKAB has subsidiaries for industrial minerals with processing plants in Sweden, Finland, the UK, the Netherlands, Turkey and China. Seismic has always been an intimate boutique festival which is so crucial for that really special niche vibe, but it also plays in our favor in terms of the feasibility of our event taking place in May. We'll be capping at a little less than normal at 2,500 attendees and that's over multiple areas across a 7+ acre property. It doesn’t matter if there are clouds over Abisko, we can take you to Kiruna’s arctic forest or even to coast of Norway!

Your guide will tell you many stories about the northern lights and Vikings and also we will take pictures and videos which we’ll send to you within 3 days after the tour.

If you bring your own camera, we will help you set it up to get the best shots.

For example, it was used to assess the level of damage in LKAB’s Kiruna mine after a seismic event. More than 30 scans were captured covering 1.2 km of underground drives that were not safe to access due to fall of ground.
