Moatize Surface Drainage Master Plan
Client name: Vale S.A. - DICC / GELCF (Coal Long Term Planning)
Duration: September 2012 - January 2013
Location: Moatize, Mozambique
Coffey used Virtual Reality to simulate potential surface drainage issues, improving the safety of workers and preventing future interruptions to operations.
Mine faced with surface drainage system issues after intense rainfall
The Moatize mine in Mozambique has faced some operational challenges due to deficiencies presented in its surface drainage system as a result of rainfall in the region which has short rain periods of great intensity.
Virtual Reality used to provide geo-technologies and hydrology expertise
Coffey provided expertise in geotechnologies and hydrology, while using Virtual Reality to simulate the hydraulic behaviour in the mine. We considered various possible scenarios to support the future design of engineering works that would help resolve current challenges, and prevent future ones from occurring.
Methodologies improving the safety of workers and preventing future operational interruptions
This project generated methodologies and technology tools that enabled Vale to more effectively:
- detect current problems and possible drainage system in the mine
- scale and allocate engineering works needed to resolve the drainage problems
- plan the mitigation of operational disturbances due to rain before they occur
- avoid loss of profitability due to last minute major intervention
- reduce risks to workers due to greater geotechnical stability
- involve and engage the various operational areas of the mine in the planning and implementation of the proposed Drainage Master Plan
