Designed primarily for those investigating the use of cover systems on mine sites, this document offers a "best practice" summary to assist mine operators, designers, and regulators to address the role cover systems play over the life of the mine, from early conceptualization to long-term performance monitoring. A conceptual model illuminates how cover system designs might affect contaminant and acidity loading. The model attempts to determine when the varying roles of cover system design (e.g., control of net percolation or oxygen ingress) might influence loadings. Acknowledgment of these unique relationships provides an opportunity to optimize cost-effective management of metal loading and acid rock drainage. The cover system design tool walks users through relevant climatic factors to optimize cover system design alternatives and meet desired performance design criteria. http://www.inap.com.au/wp-content/uploads/2018/05/global-cover-system-design.pdf
