Abstract

Abstract: Mining tailing dam ruptures are increasingly common events in South America. Due to their high potential degree for avoidance, they are considered to be technological disasters and often have a considerable impact on local populations and communities, as well as affecting the ecosystem. The failure of the Fundão dam in 2015 in the Brazilian State of Minas Gerais (is) considered one of the largest socioenvironmental disasters in the country's history. Different explanations for the causes of the disaster were put forward by various social actors. This article critically analyzes these discourses through the theoretical‐methodological reference of the social theory of discourse, with the aim of understanding the various discursive contexts of the causes of the breach of the dam. The analysis and understanding of these explanatory matrices suggested that different discourses present different epistemological approaches to the causes of the disaster, related to aspects such as sociohistorical, political, ideological, and asymmetric relations of power. The statements had different emphases, being associated with distinct epistemic positions that were often not in convergence. Moreover, certain terms and approaches reinforce or minimize processes of vulnerability experienced by the affected populations. These discourses present consents, dissents, and contradictions and when systematically integrated can improve the planning of risk management and broaden the understanding related to technological disaster occurrence.
