Open-pit mine planning has in the last decade been tackled in earnest with integer programming techniques. In particular the problem of planning the exploitation of an ore body over time, so as to maximize the net present value of the mine over its lifetime, is well suited to integer programming models and methods, which now represent the state of the art. In this talk, the models that have been developed to address this problem and some of the techniques used for its efficient solution will be reviewed. Study of fundamental mathematical structures motivated by open-pit mine production scheduling models will be touched on, and extensions of models and methods to handle challenges such as uncertainty in the ore body and the use of a stockpile to extend the life of the mine, will be discussed.
