Study goals
The objective of the study is to develop and validate a specific Risk Breakdown Structure (RBS) for mineral tailings dams, aiming to standardize the identification and communication of dam risks in the context of tailings dam safety.
Relevance / originality
The originality of the study lies in adapting RBS, a tool consolidated in engineering projects, to the specific context of mineral tailings dams. The topic gains relevance in light of recurring breaches and gaps in traditional risk classification practices.
Methodology / approach
The methodology adopted was qualitative, conducted in three stages: technical review to support the study, preliminary identification of risks through exploratory document analysis, and development of the RBS through a panel of experts using the brainstorming technique.
Main results
RBS consolidated 56 risks distributed across three areas and nine categories. Geotechnical risks stood out, such as instability, liquefaction, overtopping, and internal erosion. Social, environmental, and economic risks were also identified, which are often overlooked in traditional assessments.
Theoretical / methodological contributions
Theoretically, the study broadens the field of risk management by adapting RBS to tailings dams. Methodologically, it demonstrates the applicability of the framework as a basis for future analysis, empirical validation, and integration with multi-criteria prioritization and decision-making methods.
Social / management contributions
The study supports management by clearly structuring risks, strengthening preventive decisions. Socially, it contributes to reducing disasters, protecting vulnerable communities, and minimizing environmental damage, aligning with international standards and social demands for greater safety and transparency.
