Geotechnical Hazards and Their Potential Effects in Case of Flooding Former Open-pits

Geotechnical Hazards and Their Potential Effects in Case of Flooding Former Open-pits

One of the ways of recovering and rehabilitating degraded mining lands that offer opportunities for sustainable development of a mining area is the managed flooding of the remaining gaps of former open-pits (particularly lignite open-pits) and the creation of lakes that can take different uses. From the conservation of biodiversity to economic and social benefits, the advantages of such a solution are many. A variety of flooding strategies are essentially known, but depending on the geographical, geotechnical, hydrological and hydrogeological conditions characteristic of the region, they must be adapted to the risks that may occur before, during and after the remaining gap has been flooded. The hazards are most often geotechnical in nature and result from the contact between the rocks and the mixture of loose rocks that form the final slopes and the dump. Uh, with water. Geotechnical threats (risks) occur when it is possible to detect a future ground movement. The paper is part of a systematic study carried out under the particular conditions of the remaining gaps in the Rovinari mining basin and is essentially aimed at the identification of the key categories of geotechnical hazards that may occur under the conditions defined, the determination of the triggering factors, the process of generating negative geotechnical phenomena and their impact on the environment
