Successful mine closure or reclamation processes have various definitions in jurisdictions around the world. Setting criteria for a successful mine closure is required to measure progress towards achieving the objectives of closure. The majority of existing guidelines are based on processes – Read more... about A comparative study of regulatory approaches to mine closure with a special emphasis on the current situation in the former Soviet Union

Mine closure, the idea. Where did it begin and how did we develop our current understanding of the associated technical, environmental and social challenges? This paper will present three histories of mine closure, developed using different methods and leading to somewhat different conclusions.

The first history examines societal factors that contributed to the early ideas about mine closure. It uses the normal methods of historical research, specifically review of primary and secondary written sources, and focuses on how both competing resource uses and the development of environmental movements led to early mine closure legislation.

The second history addresses scientific and technical developments related to mine closure. It uses a method known as bibliometric mapping. Over 4,000 technical references related to mine closure were collected and analysed by a series of text-mining, statistical and graphical techniques. The results show the growth in the field as a whole from the 1960s to the present day, and also the shifts in emphasis from reclamation to more holistic closure, from the major element composition of affected waters to various minor and trace elements, and from bio-physical and chemical effects to socio-economic concerns.

The third history reviews the development of mine closure practices over the last twenty years. It draws on concept mapping exercises completed by mine closure experts in 1998 and again in 2006. It shows the transition from isolated specialties to a mature discipline, complete with higher level management processes, continuing growth in technical fields, and new interests in stakeholder and sustainability issues.

Even these three approaches together do not constitute a complete history. But perhaps they will enrich our understanding of how the idea of mine closure has changed and continues to change over time and in different parts of the mining industry.
