The seismic event of May 18th has made history, not only among those who experienced the dramatic subsidence first-hand; it has also echoed throughout the mining world. "I have received many comments from colleagues in Sweden, Finland, Australia, France and South Africa. LKAB measures and reports vibrations on the ground for seismic events in millimetres per second. The value shown is called Peak Particle Velocity, and is the greatest value that occurs regardless of the direction of the vibrations. The seismic event occurred at 3.11 a.m. on May 18th. The event had a magnitude 3.3 on the local magnitude scale and occurred at a level of -1,146 metres (from zeroing point) in the mine's foot-wall.

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.

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.

Company; Join 2020-05-19 · Swedish state-owned iron-ore producer LKAB has confirmed that all production at its Kiruna mine has stopped following a seismic event on Monday, the company said on Tuesday May 19.

All the parameters of the seismic events in the LKAB database are calculated by IMS (Institute of Mine Seismology, www.imseismology.org). The waveforms were used for re-processing of the seismic events and reﬁned estimation of the seismic source parameters (hypocenter location, local 2020-05-24 Abstract: BEMIS (Bayesian estimation of mining-induced seismicity) is a fully automatic, near real-time, robust and self-learning seismic processing solution for mining-induced seismic events. A prototype solution is tested in parallel with IMS’s routine manual processing in LKAB’s underground mines in Malmberget and Kiruna, providing four times more accurate earthquake locations based on Seismic events Öppna undermeny.

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.

Induced seismicity refers to typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the Earth's crust.Most induced seismicity is of a low magnitude.A few sites regularly have larger quakes, such as The Geysers geothermal plant in California which averaged two M4 events and 15 M3 events every year from 2004 to 2009. 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 … LKAB has begun working to secure sustainable mining operations even after 2030. LKAB has a niche position thanks to its geology, cutting-edge technology and partnership with customers. Our culture is characterized by safety, inclusion and good development opportunities.

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. LKAB has decided on a new group structure. The aim of the reorganization is to place greater focus on iron ore production and to secure sustainable long-term mining operations. At the same time, changes are being made to LKAB's group management. “LKAB faces a new situation. As a consequence of a changed market and falling world-market prices, we must now equip our Gruvjätten LKAB redovisar en stark delårsrapport för första kvartalet där det rekordhöga rörelseresultatet är mest utmärkande.

How does the seismic system work? - LKAB

The majority of such events near LKAB mines – sometimes several hundred to a thousand a day – are so minor that they cannot be felt and are only measurable with sensitive instruments. 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. 2020-12-21 · Swedish mining giant LKAB suffered a significant seismic event at their Kiruna iron ore mine. Before they were able to restart operations, they needed to gain a complete understanding of the damage. AMKVO, a Swedish remote-sensing company, was called in to map the damage with Hovermap. Although LKAB has a very delicate system for measuring rock movements, it is impossible for the mining company to predict quakes.
