Swiss-Swedish engineering giant ABB has delivered two mine hoists to Boliden Garpenberg for its Skr3.9bn ($588.74m) mine expansion programme.
Both the production hoist and man hoist include mechanical, control and drive systems however, the production hoist has additional shaft equipment and can generate 416t of ore an hour at a speed of 17m a second.
The hoists will be operated from a control centre through an 800xA control system, which can be connected with all equipment and systems to automate the production and administration of the entire mine.
ABB underground mining global market segment head Andreas Malmport said: "I am very pleased with the outcome of our projects at Boliden in Garpenberg. The main benefits for the customer are increased productivity, higher energy efficiency and improved safety."
In addition to hoists, ABB has also delivered the mill drives and the automation system for the concentrator plant of the
Garpenberg project, which is currently one of the biggest construction sites in Sweden with more than 700 people involved with the project.
Garpenberg Mine started operations in the early 13th century and is Sweden’s oldest functioning mine. It contains zinc, copper, lead, gold and silver.
Boliden acquired the mine in 1957 and in 2011 revealed plans to spend $588.74m to double the annual production capacity from 1.4 million tonnes to 2.5 million tonnes per annum, by the end of 2015.
