Observations on the Ore Pass Systems at Brunswick Mine

CIM MEMO 2008
Kamran Esmaieli, Richard Harrisson,
Abstract Brunswick Mine employs an ore and waste pass system for material transfer. This paper reviews the evolution and performance ore pass systems over the years at the mine. In particular it addresses the influence of structure, stress and materials handling on the longevity of the employed ore passes. This is made possible by a comprehensive back analysis of several case studies. Finally, the practice at Brunswick is compared with other mining operations.
