Managing the waste rock storage design — can we build a waste rock dump that works? R Barritt et al. 132 Mine Closure 2016, Perth, Australia If a WRD works it can be considered a success from its initiation through to a given time following closure. Where a site considers Zclosure from Day 1, the potential for success for it to work, is higher.
