Pit slope stability assessment and pedological characteristics of the former open-pit mine Most-Ležáky
- Výzkumný ústav pro hnědé uhlí a.s., Most
The paper addresses problematic aspects of final slope stability in the former brown-coal open-pit mine Most-Ležáky, which is currently being transformed into a pit-lake. An overview of reclamation works which have been done since the closure of the mine up to the present is provided. All the reclamation works were performed in order to provide long-term stability of the final pit slopes. The area surrounding the future pit-lake was split into several sites categorized by geological, hydrogeological, and stability parameters. Then, stability of each site was assessed from the geotechnical point of view. If the stability of the particular site was assessed as unsatisfactory, appropriate slope works and stabilisation measures were recommended. Finally, pedological characteristics of each site are provided.
