In mine planning, the Final Open Pit problem consists in finding an optimal design for an open pit mine. It has been studied mostly as a binary optimization problem until a continuous model was introduced in 2011 by Alvarez et al as an alternative to the binary one. In this talk we will show an optimal control version for this problem and taking advantage of this framework, we will present optimality conditions and numerical experiments using the Bocop solver, an open source toolbox for optimal control problems developed by Inria, which uses direct and global methods.

Joint work with Pierre Martinon (Inria, Francia) and Héctor Ramírez (Universidad de Chile, Chile).
