2021-02-24 · After being struck by a seismic event in May 2020, LKAB called in remote sensing specialist AMKVO who utilised drone autonomy and mapping solution Hovermap, to safely and quickly map damaged areas

At 06:00 Monday morning, LKAB reported that the quake caused rocks to crash into the mine and that there was still seismic activity at the site. Aftonbladet reports that there were work going on at the site at 08:00 monday morning, to get the water pumps running in the mine and prevent the water level from reaching the power plant.

Large-scale mining for ore in underground mines can lead to seismic activities. This means quaking or tremors occur in the bedrock. LKAB monitors the activity in its mines in Kiruna and Malmberget, and works to reduce these tremors. Seismic events occur when the natural tension in the bedrock changes.

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.

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.

Since 2008, significant work was done at LKAB to better understand their induced seismicity. It has been identified that the majority of seismic events in the mine

2020-10-30 · The seismic event triggered rock bursts across kilometers of drifts. Armed with accurate 3D datasets, LKAB engineers were able to start planning remediation work within weeks of the event. Therefore, in this case, we have used the national seismic system. We are planning to install geophones that have a wider measurement range," says Mirjana Boskovic.
