Design of landform elements for mine reclamation Pollard, J. A.; McKenna, Gord


Landform design is the multidisciplinary process that builds mining landforms, landscapes, and regions to meet agreed upon land use goals and objectives. Such work starts even before mining begins, carries on through mine development and operation, and continues through closure and beyond to guide post-mining stewardship of the land. It allows mining companies, regulators, and local communities to progressively reclaim the land with confidence, managing costs, risks, and liabilities, to create beneficial landscapes. Landform elements are specific physical subcomponents of a mining landform that are designed to allow the landform to meet the overall landform-scale design goals and objectives. They are typically large enough to be featured on a detailed design drawing and be built with normal mine reclamation equipment; they are usually in the 10 to 100m scale. Some elements are exquisitely designed while some are simply field-fit. Examples of landform elements include swales, mounds, outlets, watershed berms, vegetation patches, meandering toe creeks, islands, and wildlife enhancements such as snags and rockpiles. All provide efficient and practical solutions to complex mine reclamation problems. The paper provides a list of 97 landform elements for mine reclamation for common mining landforms including waste dumps, tailings facilities, and end pit lakes.
