Vale’s places a priority on optimizing its safety procedures, reinvigorating its pact with society, and providing increased transparency with regards to its dams. All information below refers to Brazil.
For these reasons, we are bringing together here our main initiatives for the management and monitoring of our dams. Explore this page and learn more about our processes and what has been done.

Since the dam collapse at Brumadinho, Vale has committed itself to eliminating dam structures that have been raised using the upstream construction method in line with recent dam legislation that determined that these types of structures are to be decommissioned.

Safety innovations for operations and communities
Vale understands the importance of technology and is therefore investing in new dam monitoring technologies. This is how we are able to provide agility and safety with our initiatives.
Hover the mouse to learn more about these technologies.
Continuous structure monitoring carried out by teams 24 h per day, with all systems centred upon these individuals safely viewing any situation, allowing for a rapid response. The integrated geotechnical monitoring centres (CMGs) are located in Nova Lima and Itabira Minas Gerais, Parauapebas in Pará, and Corumbá in Mato Grosso do Sul;
The aerial survey of dam structures is a great ally in ensuring safety and a rapid response to emergency situations. Information is gathered through means of helicopter passes performed with an electromagnetic sensor attached to the aircraft.
Development of emergency alert systems as part of Emergency Action Plans for Mining Dams – PAEBMs, such as a system for the automatic engagement of dam sirens. Sensors detect movement in structures and are able to engage sirens automatically in case of movement that exceeds established limits. The automatic engagement of sirens is a procedure that provides increased reliability and rapidity in alerting communities of an emergency situation. This process is automatic and does not depend on human intervention.
Doppler Radar and Tiltmeters, which are equipment using in detecting structure collapse. This equipment is already being used as part of the project for automatic engagement of emergency sirens, when necessary, in accordance with resolution 13/2019 from the National Mining Agency (ANM).
Operations using remote equipment in structures presenting a critical emergency level. This allows, for example, upstream tailings dams such as Sul Superior, in Barão de Cocais and B3/B4 in Nova Lima to be safely decommissioned, removing workers from the field and away from areas of risk.
Technologies that improve the gathering of data and safety with regards to decision making involving structures, such as dam surveillance robots, the use of drones for remote inspection, and expansion of automated instruments that use artificial intelligence.
Deep Drive and Helix AR2 are equipment used to measure seismic waves in tailings dams. Deep Drive is able to reach a depth of 100 m and has its own control cabin. It is engaged in case of emergency. Helix AR2 is a robot that aggregates important solutions for dam decommissioning processes.
