Mining Over 100 Stopes Per Year? ù The Perilya Broken Hill Approach to Mine Planning

Perilya Broken Hill, from its inception, has budgeted for more than 2.0 million tonnes per year from the Southern Operations. This tonnage was planned to come from in excess of 100 stopes per year in a remnant mining environment with numerous mined voids and consequent mining challenges. To mine an average of two stopes per week requires patience, flexibility and detailed knowledge to best manage the potential risks and hazards. The evolution of the Perilya Broken Hill Mine Planning Process has necessitated the establishment of a process to identify and manage these risks during the planning stage in a reliable but efficient manner. This process is to ensure that vital steps for each stope are not missed, and that each personÆs work can be tracked by other members of the team. This paper outlines the planning process from resource to stope closure.
