The National Mining Agency (ANM) has consolidated the data regarding the Stability Condition Declaration (DCE) submission campaign for the first semester of 2026. The analysis of the document allows observing the current stage of regulatory compliance of mining structures in the country and the technical attention points that impact the operational continuity of the sector.
Consolidation of stability data
According to the report, out of the 458 structures with a legal obligation to submit the declaration, 416 presented the stability certificate within the required parameters. However, the technical balance of this cycle indicates that 42 dams are currently in an embargoed situation.
This interdiction stems from two distinct scenarios observed in the report:
- Non-Attestation of Stability (18 structures): Situations where regular technical inspections identified that safety factors do not meet current regulatory criteria.
- Omission of Submission (24 structures): The lack of declaration filing within the regulatory deadline generates, by force of the norm, the presumption of instability, resulting in the immediate impediment of the structure’s operation.
Geographic Distribution and Technical Variables
The spatial analysis of the results shows a concentration of structures without a stability certificate in the state of Minas Gerais, which accounts for 50% of the recorded cases (21 structures). Geologically, this scenario is linked to areas with a high density of dams using construction methods under regulatory restriction, such as upstream raising, requiring more complex decharacterization plans.
States such as Amapa and Mato Grosso also present indices requiring attention.
Classification into Emergency Levels
The report details the classification of structures that did not obtain attested stability, correlating them to their respective Emergency Levels (NE):
- 34 structures at Emergency Level 1 (NE1): Identification of anomalies that require scheduled repairs, without compromising immediate integrity.
- 7 structures at Emergency Level 2 (NE2): Cases where corrective interventions were not sufficient to resolve the detected anomalies.
- 1 structure at Emergency Level 3 (NE3): Critical condition requiring total readiness and real-time monitoring.
Implications for Mineral Operations
From an asset management perspective, the embargo resulting from the non-submission or denial of the DCE interrupts the operational flow, preventing the disposal of tailings and, consequently, affecting the productivity of processing units.
