ABSTRACT
The paper outlines through multiple analyzes the fundamental parameters influencing important changes in slope safety of tailings retention structures associated with thermoelectric plants. Essential element leading to variation of stability factor is the position of the seepage curve level, as a result of numerical previous calculations, which may bear discussion about the influence of the values obtained. It was also analyzed the influence of operating regulation of the entire hydraulic scheme. Study conclusion points out that beach length, height reserve (clearance) and drainage systems in operation ensure the tailings dam safety. Any change in these conditions could lead the structure to its limit equilibrium state.

Keywords: tailings dam, hydraulic disposal, seepage curve, operating regulation, slope stability
