Mine Closure Wiki - Databank for Mine Closure

摘要

Mine closure is an essential part in the development of eco-efficient, sustainable mining. When mines close they leave behind open spaces (ground workings) and piles of mineral waste materials which may deteriorate the environment in the long-term, if not closed properly. Extensive knowledge on suitable closure technologies and related research methods as well as on site-specific factors affecting selection of proper closure technologies are required for successful closure. To reach the best results, planning of mine closure should be started as early as possible - ideally during the feasibility study phase, before any mining operations begin.To provide guidance on mine closure and to reduce negative environmental, societal and economic impacts of closure, Geological Survey of Finland (GTK) and Technical Research Centre of Finland (VTT) developed Mine Closure Wiki - a wiki-based technology resource on mine closure. The objective of the Wiki is to promote the selection of technical methods for the closure and to facilitate smoother closure planning and permitting.The Mine Closure Wiki includes the best practices and legislation pertinent to closure, systematic evaluations of the key closure methods and technologies, and benchmarked case studies on the performance of closure technologies. The Wiki is an open internet resource intended as an every-day tool for mining operators, authorities, consultants and researchers for planning, permitting, executing, and monitoring of mine closure. The Mine Closure Wiki was published in October 2015.
