Proposals for Reducing Damage Caused by Dams Collapse in Pitinga - Amazonas

Abstract

Mining is an extractive activity that interferes with the economic, environmental and social environment. Thus, its intrinsic characteristic is locational rigidity, environmental transformation and the generation of social and environmental risks. Thus, this study aimed to present in the literature what is the best mitigating measure to be adopted in order to try to reduce the impacts on possible collapses in the Pitinga tailings dams in the Amazon. From this study it can be stated that among the 29 dams located in the State of Amazonas, 8 are from ore tailings and are located in the municipality of Presidente Figueiredo, in the Pitinga region, as regards supposed risks of a disaster, the perceived scenario in Minas Gerais can hardly occur, since the tailings dams have a natural containment because they are built in valleys. However, in order to reduce damage and prevent possible collapse in ore enterprises, it is essential that mitigation measures are used to compensate for environmental damage caused by the practice of ore extraction.
