Bästa kvartalet på fyra år för seismiska jätten TGS

Today, it’s the world’s largest underground iron ore mine, producing around 27 million tonnes of iron ore a year. The seismic event triggered rock bursts across kilometers of drifts. 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.

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. 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.

Quake damages Kiruna mine but no injuries - Radio Sweden

2 days ago 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. 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. LKAB constantly monitors seismic activity. It does this with hundreds of instruments called geophones that detect shock waves in the bedrock.
