ABSTRACT: Geomembranes are among the alternatives for materials used in cover systems to control acid mine drainage (AMD) upon closure of mining waste disposal sites. An ongoing investigation has highlighted the paucity of information in the literature on covers with geomembrane components for mining waste applications (i.e., tailings and waste rock). The main outcomes from this investigation have been aggregated to identify factors that control the performance of geomembranes in mining waste cover applications and to generate a summary of recommended practices in terms of geomembrane installation, mechanical and thermal stability, transport characteristics (primarily water and air/oxygen), degradation, and overall long-term performance. This article presents and discusses the main results from this evaluation and addresses the main concerns for the closure and reclamation of reactive mining waste disposal sites in particular using geomembranes.

RÉSUMÉ: Les géomembranes sont parmi les matériaux employés dans les systèmes de recouvrement afin de contrôler la génération de drainage minier ac Une étude actuellement en cours a montré dans les couvertures pour la restauration des parcs à résidus et des haldes à stériles. Les principaux résultats de cette étude ont été utilisés afin performance des géomembranes dans les recouvrements et proposer une synthèse des de stabilité mécanique et thermique, de dégradation et de performance à long terme. Cet article présente et discute les principaux résultats de cette étude et aborde les principaux défis liés à la fermeture et à la restauration des aires
