Abstract:
This paper reviews state-of-the-art rehabilitation technologies for damaged landscapes including large-scale mining operations. It is based on a selected case study, which G.U.B. Ingenieur AG planned, conducted, and managed in Germany. Tasks and challenges: • The strong need for rehabilitation of rock and waste dumps and abandoned open pits as part of mine closure operations. • Rock mine drainage (i.e. acid mine drainage) from abandoned coal, uranium and poly-metallic mine sites. The approach: • Development and implementation of multi-barrier systems. • Site specific adoption concerning the real situation (i.e. geological, hydrological, geotechnical, climatic conditions). • The multi-barrier system consists of a combination of natural based layers (1–3, i.e. topsoil, clay, limestone) with technical products (1–2, i.e. geo textiles) and with constructed internal and external drainage systems. • Installation of such multi-barrier systems on the top of rock and waste dumps and on the basis bases of sites, which ensures complete containment for the purpose of stepwise storage of hazardous and radioactive waste and rock material responsible for AMD/RMD processes. • Special focus on ensuring long-term stability.
