Welcome to the Mine Closure Wiki and Closedure Project Pages!

Mine Closure Wiki

Mine Closure Wiki ( is an open internet resource on technologies and approaches used in mine closure. It provides guidance and tools for planning, executing and monitoring of mine closure. Mine Closure Wiki is intended for mining operators, authorities, consultants and researchers to

  • smooth the mine closure planning and permitting processes,
  • ease the selection of technical methods for key closure operations, and
  • to reduce environmental, societal and economic impacts of mine closure.

Mine Closure Wiki

  • provides an overall description of best practices and legislation pertinent to closure,
  • presents systematic evaluations of key methods and technologies of closure,
  • benchmarks national and international case studies of performance of closure technologies in areas of post closure water management, water treatment, wastes and waste facilities, and post closure monitoring, and
  • presents results of research and development studies performed in Closedure.

Mine Closure Wiki was developed by the Closedure Project, funded by Tekes Green Mining programme. The project was carried out from 2013 to July 2015 by the Geological Survey of Finland (GTK) and VTT Technical Research Centre of Finland Ltd.

Structure of the Wiki

Mine Closure Wiki consists of seven sections. “Closedure Project” presents the project behind the Wiki and “Guidelines and templates for contributions” provides details how to write a Wiki article to the Mine Closure Wiki. The other five sections provide guidance on the key themes of mine closure: “Mine Closure process”, “Water management”, “Water treatment”, “Wastes and waste facilities” and “Monitoring”.

Mine Closure Process presents overview of basic principles and best practices of mine closure and mine closure planning, closure objectives, and legal requirements for mine closure. Water management, Water treatment, Wastes and waste facilities and Monitoring sections all include: closure objectives, evaluations of key methods and/or technologies relevant to mine closure, case studies of long-term performance of closure technologies, and R&D studies carried out during Closedure Project. Monitoring provides also check-lists of the available methods for post-closure monitoring of mine sites.

Management of the Wiki

Mine Closure Wiki is updated and managed by the Geological Survey of Finland. Terms and conditions for the use are presented in the Legal Disclaimer of Mine Closure Wiki.
