Hydraulic performance of liners in tailings management and heap leach facilities

摘要

The use of lining systems to manage the risks from leachate in tailings management and heap leach facilities is common practice. However the relative hydraulic performance of such lining systems is often misunderstood with consequent design and environmental risk implications. This paper examines the hydraulic performance of different lining systems and the longevity of such systems during the life of mine. A series of tools are described and discussed to illustrate the performance assessment processs.
