摘要：Objetive: Recently in the state of Minas Gerais disasters has happened with the iron ore sector, such as what occurred in the city of Mariana in November 2015 and also in the city of Brumadinho in January 2019, both caused by dam rupture. These tragedies, besides having a social impact such as the death of people, also have consequences for the other sectors of the Brazilian economy. Using the input-output matrix inoperability approach, the article aims to analyze such as the interruption of activity in the iron ore extraction sector in the state of Minas Gerais dissipates to the other sectors. The results obtained suggest that in addition to the iron ore extraction sector, the sectors most affected by this inactivity, although in smaller proportions, are the physical capital production sectors, such as machinery, equipment and automobiles, as well as fuel..
