During 9 years in this position, and recently at the Innovation and Technical Support Team, I had
the opportunity to contribute to Vale’s business development by:
- Implementing a method and system to measure elastic parameters in rock masses
continuously, despite of the presence of discontinuities.
- Implementing a test facility that permitted to select and assess the effectiveness of a
radiation source intended to geophysical logging in high density fractured iron formations,
which became a standard method at Vale’s Iron Ore Exploration Department.
- Developing a method that made possible to measure gamma density inside drilling rods,
eliminating the environmental risk of radioactive source stuck in boreholes and increased
gamma-gamma data recovery from around 48% to above 80% improving the geological
knowledge of Vale’s deposits and the density database to support geotechnical projects
and resources estimation.
- Providing technical directives for the implementation of two local seismological networks
capable of separate natural from operational seismic events in a local scale, allowing the
implementation of predictive models to analyze the impact of such occurrences on
geotechnical structures.
- Designing of a toolset to correlates multi physical properties of rock material from blast
holes with geomechanical classes to design blasting operations accordingly, mitigating
excessive particulate emission, back-break and crusher oversize problems.
- Implementation of disruptive exploration technology such as thermal pulsed neutrons log,
plasma drilling and integrated petrophysical/multi spectral analysis.
