Factors influencing the flooding process of former coal open-pits

Purpose. This study aims to identify the main factors that influence flooding process of remaining gaps open-pits comprising essentially velocity and duration flooding, but also stability in situ dump slopes during after water quality order ensure takeover future function land as soon possible safety objects local communities. Methods. Establishing three categories from a quantitative qualitative point view open pits. Analysis key gaps, terms their contribution reducing or increasing flood reserve different types slopes. Findings. The interdependence cumulative action materializes worsening strength characteristics rocks changing state stress deformations rock mass. Originality. paper provides detailed description interactions between these in-fluence on process, stability, factor safety. Their are highlighted through case conducted at Peșteana mining perimeter level. Practical implications. can cause loss slope process. Unexpected geotechnical phenomena such landslides, liquefaction, suffosis, falls and/or pit lake be hazardous natural anthropic Safety is essential. Therefore, this suggests taking into account most important when evaluating floo-ding possibility gaps. Engineers, researchers, mine planers, authorities, students will have essential information know where special attention needed former open-pits.
