Jones & Wagener specialises in optimised rehabilitation designs for opencast mines and discard facilities to find the best possible solution to:

• Satisfy minimum material movement that meets the EMPr requirements, and at the same time
• Ensure a sustainable, free-draining, natural post-rehabilitation topography.

We use our in-house developed optimisation software to undertake and optimise the rehabilitation designs.

Specific services include:

• Optimisation of mass movement of material
  › Critical from a cost perspective as the construction and capital costs are directly related to the
  volume of material to be moved to achieve the required topography.
• Optimisation of rehabilitation design
  › Our software tool takes into account parameters such as material cut and fill volumes and
  the maximum allowable slopes to maintain an optimised sloping model topography.
• Predictive mine modelling
  › Develop a realistic post-mining model through mining simulation, before the mining takes place.
  This is an essential tool for undertaking concurrent rehabilitation optimising material placement,
  hence minimising future double handling.
• Long-term erosion modelling
  › Proactively design preventative measures that reduce the likelihood of future erosion
  on rehabilitated topographies.
  › Reduce post-rehabilitation maintenance costs and long-term liabilities.
• Closure cost estimates
  › Conduct assessments to estimate closure costs in accordance with regulatory requirements.
• Strategic placement of materials to meet annual concurrent rehabilitation targets
  › Avoid unnecessary double handling of material and significantly reduce rehabilitation
  construction costs.
