Some of the present metallic ores mines are located in areas formed by a heterogeneous fractured massif where groundwater flows preferentially through fractures. Underground mining in these zones can cause impacts in streams, lakes and change the natural water balance of the watersheds, leading to conflicts between traditional uses of water and the mining activity. Quantification of these impacts is crucial for the sustainability of the operation time. In this work we develop a 3D integrated hydrogeological numerical model of a mining construction and operation in a fractured media.
