Abstract

The work will initially be about a study about the disaster of the rupture of the Samarco mining dam, located in Bento Rodrigues, municipality of Mariana. The accident will be explored in order to highlight the main factors that led to the rupture of the dam. Using articles and reports already published, will be studied and explained the set of factors that caused the accident. In a second stage, the incident will be addressed in order to highlight all the environmental impacts as well as the socioeconomic impacts in the region. This study should also serve for the collection of corrective and mitigating actions, developed later. In the third stage, the focus will be to survey possible actions to prevent the rupture of the dam, or at least minimize its socio-environmental impacts, in the event of disruption. In addition, a set of actions will be presented that are intended to minimize the impacts caused after the accident, and possible predictions of reestablishment of the local fauna and flora.
