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. 

Situation

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.

Solution

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.

Result

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
