Water is a precious resource for the Carlota Copper Mine in Globe, AZ, and environmental regulations necessitated zero discharge from mine operations to the nearby Pinto Creek watershed. Construction of new heap leach pads in 2008 dictated the need for a diversion channel to maintain the flow of Powers Gulch without introduction of any leach effluent-Velocities associated with critical and supercritical flow required design of a series of drop structures capable of energy dissipation to control erosion. The use of the ARMORMAX® Anchor Reinforced Vegetation System (ARVS) was the right choice to line the drop structures, based on its high UV stability and unvegetated hydraulic performance. The cost savings over conventional concrete and gabion linings saved significant construction time and costs for the mine owner.
