Base Metals Mine, Northern Australia
Okane provided landform and cover designs for existing waste rock dumps in a high seasonal rainfall climate.
Hydrological assessments were undertaken to provide input variables for landform modelling, cover system design, and drainage. Various options for plateau and embankment drainage systems were considered. The drainage design considered erosion protection during extreme rainfall events and sediments during cover system construction. The ultimate drainage system was designed to become maintenance free and simulates natural systems.
