Bathymetry Surveys of Post-Mining Pit Lakes Formed after Exploitation of Lignite

Abstract

Flooding of post-mining voids is one of the most common methods of post-mining areas reclamation. The article presents selected post-mining lakes investigated within the research project “Risk assessment of final pits during flooding” (RAFF), co-financed by the Research Fund of Coal and Steel and the Polish Ministry of Education and Science. The main objectives of the project are focused on the development of comprehensive models that can be used for risk assessment purposes. The innovative outcomes of the project will help to elaborate methodologies and guidelines to improve the safety and security of the flooding of post-mining open pits as well as sustainable management of the environment. In this paper, the results of bathymetry surveys carried out on pit lake Lubstów belonging to the PAK Konin Lignite Mine SA are presented.
