Mine Closure

Prior to the mid-1980s, the issue of mine closure had a low priority for most governments (and hence for most mining companies), as evidenced by the large numbers of abandoned mines that exist in virtually every major mining country. Very few countries had in place mineral policies and legislation that provide for comprehensive mine closure (Clark and Cook Clark 2000). This has now changed and most countries where mining takes place, now have mine closure regulations. The basic components of a comprehensive mine closure policy and associated legislation, as further detailed in this chapter, include: a comprehensive mine closure financing arrangement; (2) specific provisions for abandonment and post-closure activities; (3) specific provisions for rehabilitation; (4) inclusion of mine closure planning in the Environmental and Social Impact Assessment; and (5) monitoring and enforcement procedures to ensure compliance.
Mine closure

The current approach of mine closure planning is highly technical-managerial involving stage-by-stage requirements which are mostly guided by legislation and principles of risk prevention and litigation avoidance. The factors shaping the design, implementation, and monitoring of mine closure strategies are international in dimension. This is a positive development because global mining companies leverage themselves against each other in developing stringent standards of performance for themselves. However, the focus has been on new and future mines which neatly fit the formulations of a ‘planning-before-commencing’ approach that assumes a blank-slate as a starting point for the mine closure process, envisioning a post-mining future.

In starting any mining operation, a plan for mine closure is one of the important aspects that need to be addressed. An abandoned or poorly closed mine is a liability to the governments, communities and the mineral companies (Bell et al., 2006). Adequate mine closure is vital in achieving mine sustainability. If the closure is not properly planned or not implemented according to the rules and guidelines, there can be pollution and hazards which can be continued for many more years or generations. Therefore, the overall objective of mine closure planning is to reduce the long-term environmental, social and economic impacts after termination of mining.
Cover systems and landforms for rehabilitation of mine waste storage facilities: Practical insights
Published in CIM Journal, 2021
One of the principal drivers of the features and geometric layout of a MWSF final landform design should be the planned end land use. This should be determined through meaningful consultation with stakeholders, particularly local communities, at the start of the mine closure planning process. Initiating mine closure planning prior to the start of operations can save considerable costs at closure (Finucane & Pershke, 2009). Landform design requires a multidisciplinary approach that includes all pertinent stakeholders and technical specialists in the design process. More complex landform designs could require as many as 12 specialists, including a traditional land use specialist, reclamation specialist, vegetation ecologist, wildlife biologist, wetland biologist, hydrologist, hydrogeologist, geochemist, soil scientist, geotechnical engineer, mine planner, and landscape architect (Landform Design Institute, 2021).
