【 摘 要 】

The mining activities developed in the Arie? middle basin affected this region from various points of view: environmental, economic and social. The activities associated to the mining industry, either the exploitation itself, or those associated to mine closures, represent a significant risk source for the environment and for the local population. The gold – silver and copper mining exploitation has permanently changed the relief forms, having profound negative consequences on local and regional level. The Arie? middle basin partially overlaps the Golden Quadrilateral in the Apuseni Mountains, which resulted in the development of 11 tailing dams belonging to four mining exploitations. As to the structural stability of these mining waste deposits, ravines and rills can be observed on slopes, manifesting a progressive trend. Therefore, the risks induced by extreme atmospheric phenomena or by their combination can have significant consequences, triggering technological accidents. The paper also includes a matrix risk assessment performed on the eleven tailings dams included in the investigation area.
