The ground moved in a way that no other mining earthquake in Sweden could.
Uppsala University's senior lecturer in seismology, Björn Lund, told SVT in May 2020.
Then LKAB expects full production
New field sites have now been driven in next to the area, about 800 meters destroyed, to access the ore and open production again.
The preparatory work with production drilling and rock reinforcement is in full swing.
- We start with the production shootings with waste rock in April.
We do not know exactly when we will start with production shoots in the ore body, but guaranteed in 2022, says LKAB's mining manager in Kiruna, Joel Kangas, who expects full production in mid-2023.
Must create balance for the mining of the future
The demolished area "Block 22" has affected the entire mine's balance and thus the total production.
Therefore, the balance, the so-called sequencing between the different areas of the mine, must be restored.

The sequencing can be translated to how to mine in the mine - in what part and at what depth.
And it's about how to deal with the stresses in the rock when the ore is taken out underground.
- Everything fits together so we expect a 15-20 percent production loss during this time, says Joel Kangas.
