Induced seismicity in Basel led to suspension of its HDR project. A seismic hazard evaluation was then conducted, which resulted in the cancellation of the project in December 2009. 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.

Beton Event 2020 5, 12, 19, 26 november 2020 Voor het eerst in het bestaan van de Betondag, vindt deze niet plaats in een fysieke hal, maar ontmoeten we elkaar online op het Beton Event 2020.

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. Meet LKAB Minerals UK's Gypsol team at Build it Live South East on 9 - 10 February at the Kent Event Centre, Detling.

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.

We are planning to install geophones that have a wider measurement range," says Mirjana Boskovic. The seismic event reached a moment magnitude of 4.2.

This is the reason LKAB does not measure event magnitude on the Richter Scale but uses a local scale. 2020-10-30 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. 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. 2020-12-21 Analysis of the seismic event in Kiruna on May 18th completed.
