The RAFF project aims to research issues related to pit lakes, which is one of the most common uses of post exploitation voids. The main achievements in the projectare connected with the creation of comprehensive models that can be used for risk assessment purposes. Innovative outcomes of the project will contribute to methodologies and guidelines to improve the safety, security, and environment aspects of flooded open pit mines. The project will carry out in-situ investigation, laboratory tests, and numerical and physical modelling to achieve the objectives.
Risk Assessment of Final pits during Flooding (RAFF) project is the first project funded by RFCS (Research Funding for Coal and Steel) that deals with geotechnical risks linked to the flooding of opencast lignite mines in Europe. In order to guarantee the best safety conditions of the flooding processes, the associated risks of flooded final pits instability is being evaluated. A methodology is being developed to ensure that pit lakes are monitored over the long term.
The main objectives of the RAFF project are to identify risk factors for the post exploitation pit lakes, develop a methodology for evaluating the geotechnical state of created reservoirs and the hydro-geochemical changes in the water of these lakes during and after the process of flooding.
The RAFF project is coordinated by the “Poltegor-Institute” Opencast Mining Institute. It was launched in June 2019 and will end in June 2022. There are twelve European partners involved in this project.
Identification of problems and threats in the final pits.
In this WP, previously flooded open pits will be chosen for gathering information about crucial factors that influence pit lakes during the flooding process. The specific objectives are...
Geotechnical characterisation and modelling of reservoir slopes.
