MINE CLOSURE AND POST-MINING MANAGEMENT

By Christophe DIDIER
President of the Mine Closure Commission:

"Taking part in the mine closure commission has been a wonderful experience.
I would like to warmly thank each member for his generous and precious involvement in the commission process, from a technical but also and probably above all, from a human point of view.

An Optimisation Approach to Materials Handling in Surface Mines

In the surface mining industry the equipment selection problem involves choosing a fleet of trucks and loaders that have the capacity to move the materials speci ed in the mine plan. The optimisation problem is to select these fleets such that the overall cost of materials handling is minimised.

A new algorithm for the open-pit mine scheduling problem

By the Autors:

    For the purpose of production scheduling, open pit mines are discretized into threedimensional arrays known as block models. Production scheduling consists in deciding which blocks should be extracted, when they should be extracted and how each extracted block should be processed. Blocks which are on top should be extracted fi rst, and capacity constraints limit the production each time period.
