The quantity of land affected in the extraction of lignite in opencast mines is vast. Former mining activities leave behind numerous mine voids, which will mostly remain as artificial lakes. Overburden dumps are stretched over large areas. These areas present themselves as often uninhabitable and difficult areas for construction without further site investigation and understanding mostly remain as artificial lakes from rising groundwater and flooding.
GUB AG is one of the consulting partners of the LMBV Ltd., the mining company which is the owner and responsible for the affected areas, it was their responsibility to come up with a solution to resolve the complex geotechnical problems and ensure the area becomes safe and parameters assessed such that decisions can be made on how to stabilise the area for the future.
