摘要：In order to analyze the influence of groundwater from the slag heap of the lignite mine of As Pontes (Galicia) on the mining adjacent lake it has proceeded to make a hydrogeological characterization of the slag heap. For this, it was necessary to make different hydraulic tests at different points representing the dump to estimate the hydrodynamic parameters and identification of the different hydrogeological units, which can be described as independent. In this study, we conclude that external covert of dump has homogeneously distributed values of permeability of clavey silt. Therefore, the possible infiltration and possible percolation to deeper positions and later discharge to lake by adjacent slopes is minimized. So, the influence of groundwater discharge is null..
