Abstract:
Responsible Life Cycle Management (LCM) of mines has received much attention in the South African legislation. However, there is currently a mis-alignment between the mining industry and the various government authorities pertaining to the issue of mine closure or end-of-life management. The main reasons for this are unclear and unformulated approaches to rehabilitation with a subsequent legacy of unsuccessful mine closures that have wrongly been issued by the government from a sustainability perspective; this has posed an excessive economical burden for the mining industry. In this paper, a Mine Closure Model (MCM) based on project management principles, including risk management and concurrent engineering, is proposed to manage the closure process and assist the governing body with the effective evaluation of closures and the issuance of certificates. Mine closure or rehabilitation objectives can be achieved whilst managing the resources (of industry) optimally and aligning the closure process to meet the end requirements of stakeholder groups.
