摘要

The development and application of paste fill,cement slurry aggregate fillrnand shotcrete bulkheads at Mount Isa Mines is described.The progressivernchanges in filling style in the Mount Isa copper mines from a dry fillrnbased cemented rock fill to tailings based paste fill and slurry fills isrnexplained.The development of shotcrete arched bulkheads andrnengineered drainage system is described.Details on how Mount IsarnMines has achieved approximately 30 per cent cost reduction in backfillrnoperations through innovations are given.The development of a rockyrnpaste fill is explained.
