|EXPRESS™ Optimum Haul Road Design Package
In 1965 Dr Lerches and Dr Grossmann developed a pit optimisation system (the LG) using a mathematical concept called graph theory. This system has become the basis of
many pit optimisers available today (eg. Whittle, MineMap, and others).
Twenty years later, graph search theory was developed to accommodate the massive data sets required by expert systems for automated decision making.
Ten years further on, the Optimum Planit research team, led by Dr Tim Gill (with the aid of industry), developed dynamic graph search theory to accommodate dynamic,
massive data sets. This research is incorporated into the unique software called Express.
Express is the complete Optimum Haul Road Design Package for use within the mining or construction industries.
The Benefits of Express
Express is a true optimiser that calculates the ultimate cost benefit solution to your haul road requirements, from the bottom of the pit to the top. Substantial cost
savings are obtainable and the system provides the optimum road reserve as a CAD file and a gridded pit surface for contouring and volumes.
Express automatically provides an optimum cost based solution or interactively provides the best solution according to your design constraints. For example, you can prevent
the road entering certain parts of the pit or force it to exit at preferred locations and from a preferred direction. The system also allows you to step back through lesser
cost effective solutions thus providing sensitivity analysis on the road design.
Express Haul Road Optimisation
Express reads Whittle 4D/4X input files and runs under the Microsoft Windows operating systems. Online documentation provides easy to follow guidelines on the use of
