Mine reclamation — the necessary component of a successful mine closeout. It is a task that does not generate profit for the mining company, but it can be one of the most visible examples of a mining company’s commitment to sustainable and environmentally responsible mining. Therefore, it is paramount for mining companies to utilise technologies that allow for a complete, yet economical reclamation pursuit. Computer aided earthmoving systems (CAES) is a convenient tool that can allow mining companies to use large-scale mine equipment to successfully implement and complete massive earth moving projects such as tailings dam reclamation quickly and efficiently. Mine equipment that is no longer being used in active mining activities can be utilised for reclamation purposes, obviously reducing capital and potential operating costs, or saving the mining company millions of dollars in equipment rental fees. In addition, mining companies can self- perform the reclamation work, keeping their workers employed and minimising expensive subcontractor costs. Finally, the CAES system drastically reduces the number of surveyors and grade checkers required to provide grade and design control for the reclamation work. This paper is based on experience reclaiming tailings and mine waste stockpiles using CAES in the western United States. Included in the discussion is a brief overview of the CAES system, its setup and implementation during reclamation, design considerations that enhance the usefulness of the CAES system, and various problems and solutions encountered and solved during its use. In the end it is demonstrated how CAES brings success to mine reclamation.
