Toquepala: DYWIDAG Strand Anchors stabilize Anchor Wall in the World’s fifth largest Copper Mine

The Toquepala open pit mine in the Tacna region of southern Peru is the world’s fifth largest copper mine that also produces molybdenum, silver, gold and zinc.

The owner, Southern Copper Corporation, is building a new copper concentrator in order to double its copper production from 60,000t to 120,000t per day.


Within the scope of the capacity expansion project, earth work had to be carried out. During the work, a massive anchor wall had to be built and tied back with permanent DYWIDAG Strand Anchors.

The strand anchors were installed in 7 layers, grouted and tensioned. To anchor the wall, DSI-DYWIDAG Construcción Peru produced and supplied more than 1,000m of permanent Type 7-0.6" and 9-0.6", 40m and 45m long DYWIDAG Strand Anchors.
