Scientific monitoring of the redevelopment of brown coal mines in eastern Germany

Considerable research work has been undertaken in conjunction with the reinstatement and recultivation of former opencast brown coal mining areas. This manual sets out the key scientific factors considered and results obtained, and thus provides an overview of current know-how in the field of the sustainable redevelopment of mines.

 

Summary

The decline of open cast brown coal mining in eastern Germany has generated the need for the fundamental reinstatement of entire landscapes over large areas. Requirements to be fulfilled are as follows:

  • The restoration of an area of nearly 1,000 km2 to a useable condition, and the ecologically and economically appropriate re-incorporation of this land into the region concerned;
  • The securing of residual surface mining excavations, including over 1,000 km of working faces;
  • The rectification of a water deficit of some 13 billion cubic metres and the restoration of an essentially self-regulating water balance;
  • The stabilisation or removal of ecological contamination from soils and groundwater.

This manual sets out the main substance and results obtained from the large number of research projects which have been devoted to the problems arising in this area, and thus provides an overview of current know-how in the field of the sustainable redevelopment of mines.

Subject areas covered include the following:

  • Geotechnics, including the issue of the stability of land
  • Water management in relation to groundwater, residual mine working lakes and their fish population
  • Soil quality and issues of agricultural or silvicultural recultivation
  • Issues of nature conservation in the post-mining landscape
  • Management of contamination associated with mining operations
  • Monitoring and control systems for the various redevelopment measures undertaken
  • Socio-economic issues associated with recultivation
