Impact of High Fill Loads on Geomembrane Liners
The highest geomembrane lined fill structures in the world to present day are heap leach pads at more than 150 m in granular fill load height. A few geomembrane lined tailings dams and several mine waste rock piles with geomembrane lined interior water seepage dam barriers are planned to reach 200 m to 420 m in fill load heights, respectively. The most effective state of practice liner system to withstand high fill loads and maintain a low permeability seepage barrier is a composite clayey soil or bentonite geosynthetic clay liner in direct contact with a flexible geomembrane liner and with an overlying drain system to maintain low hydraulic heads on the composite liner. This paper discusses the impact of high loads on composite liner systems by focusing on the more robust loading experiences gained from heap leach pads compared to landfills, where ore materials are nearly twice the density of solid waste landfill materials.
