The Cuiabá Mine: Very Deep Gold Mining with Ground Support Products by DSI Underground
The Cuiabá Gold Mine in the federal state of Minas Gerais in Brazil has a long history. The first site development by the Dias and Gomes families dates back to the year 1740. In 1985, large scale extraction started with 1.2 thousand tons per day of mined mineral.
The mine has been undergoing expansion since 2005, and the drifts of the mine located in the mountains attained the sea level at a depth of 1,019m in 2008. From 2011 to 2015, more than a million ounces of gold were mined at the Cuiabá Mine.
DSI Underground Brazil has co-operated with the owner AngloGold Ashanti since 2009.
The DSI Underground team is supporting the operator with training sessions and offers support in the application of the ground support products produced and supplied by DSI Underground. As the mine extracts gold in increasingly deeper layers, DSI Underground also supports the owner with specific tests for new products and technologies.
Furthermore, DSI Underground supplies the mine with the products and systems necessary for stabilizing the drifts. 3m long 22mm Ø rock bolts are used for stabilization. The products manufactured and supplied by DSI Underground also include 28 x 300mm FASLOC® Resin Cartridges.
