A framework for assessing hazards related to pit lakes: application on European case studies

Abstract The number of abandoned mines is continuously increasing in the world. sustainable exploitation these a top priority globally. Pit lakes created mining sites provide benefits and present risks for region. This paper presents methodology to assess natural hazards related pit lakes. proposed framework based on well-established internationally accepted risk management standards allows assessment long-term stability Potential ground movements, water pollution, fire are presented, their impact evaluated feedback international experience. was applied 13 European former coal lignite mines. A Most lake carried out, using qualitative weighted probabilistic approach that considers overall individual effect identified hazards. Results showed main potential slope stability, flooding.
