Since the catastrophic failure of the Brumadinho tailings dam in 2019. The Brazilian government requested that a detailed report on the stability of all tailings dams be provided. In the review of the reports and constant observation of the tailings dams, fissures were found in one tailings dam. This alarmed everyone and it was requested that an investigation be carried out to find the possible causes of the cracking and based on this to propose a reinforcement to stabilise the cracked area of the tailings dam. The objective of this work is to carry out an investigation to identify possible causes of fissuring in a tailings dam and to propose a reinforcement to stabilise the fissured area if it does not comply with the minimum safety factors required by the Brazilian government (safety factor (FoS) > 1.5 for a static state). From the present investigation, it was observed that the tailings dam has factors of safety (FoS) between 1.0 and 1.2 for the static state. Therefore, a reinforcement was proposed with the objective of increasing the stability of the dam, with which a factor of safety (FoS) >1.5 was obtained. In this research work, it was identified that there were some deficiencies during the construction process of the tailings dam and there are information gaps to perform a more detailed geotechnical characterization, so it is necessary to perform an additional geotechnical campaign.
