Resumo: dc.description.abstract | The increase in the water table and the increase in pressure inside the dam massif conditioned the reduction of the Safety Factor and, consequently, indicates a condition of instability. The objective of this article is to evaluate the behavior of the water table in the massif of the tailing dam under the influence of closure. The evaluation consisted of the technical analysis of the instrumentation history for the interpretation of the graphs, performing the transparency between these data and subsidizing the choice of boundary conditions for the flow analyzes carried out by the Slide2D software. The results visualized in the graphs and in the percolation analysis indicate that the water table depleted the traffic after the decommissioning stage of the structure, before the stabilization stages and hydrological and hydrogeological control. The study points out that the decrease in the water table is associated with decommissioning and, above all, tailings management during dam operation. Although a hydrological and hydrogeological control stage was carried out 4 years after decommissioning, this had the objective associated with closing the structure, once the internal conditions were controlled. | pt_BR |
