Jokeri Light Rail will facilitate crosstown traffic in Helsinki metropolitan area
We carried out the largest tunnel blasting contract in our history in the world's biggest underground iron ore mine in 2009 - 2014.
Swedish LKAB is Europe's leading producer of iron ore. Kiruna mine in northern Sweden is the world's largest underground iron ore mine. The mine employs 2 000 employees.
The mining job risks are different than any other in rock engineering. “Even minor power outages or fires may suspend work for a long time,” says Regional Director Kari Korhonen from YIT.
"One of the big challenges of Kiruna contract was a correct resourcing of Sweden's northernmost town. We acquired, for example, new machines and left the old ones as a reserve to speed up work. We completed the work sooner than scheduled and with the highest quality, according to the inspector,” says Kari.
