Optimal control approaches for Open Pit planning

Abstract : This work tackles the Open Pit planning problem in an optimal control framework. We study the optimality conditions for the so-called continuous formulation using Pontryagin's Maximum Principle, and introduce a new, semicontinuous formulation that can handle the optimization of a 2D mine profile. Numerical simulations are provided for several test cases, including global optimization for the 1D Final Open Pit, and first results for the 2D Sequential Open Pit. Results indicate a good consistency between the different approaches, and with the theoretical optimality conditions.
