Red Dog Mine Alaska: Baugrundverbesserung im Permafrost

(PresseBox) (Alaska, USA, )
Im Nordwesten des US-Bundesstaats Alaska, rund 170 km nördlich des Polarkreises und knapp 1.000 km nordwestlich von Anchorage, liegt die Red Dog Mine, eine der größten Zinkminen der Welt. Seit Ende der 1980er Jahre wird die Mine im Tagebau betrieben und liefert rund 10 % der Zinkproduktion weltweit.

Aufgrund der Lage in der Polarkreis-Region befindet sich die gesamte Mine in einem geologischen Permafrost-Bereich, wodurch der Boden ab einer bestimmten Tiefe dauerhaft und vollständig gefroren ist – mit Ausnahme einer aktiven Zone nahe der Oberfläche, die im Sommer auftaut und im Winter wieder gefriert.
