To develop a medium-term stochastic optimization framework for open-pit mining complexes that simultaneously incorporates explicit loading equipment constraints and processing plant uncertainty.
Integrated explicit tracking of shovel movements over a 12-month horizon to match extraction schedules with operational loading capacities.
Utilized high-order simulation to generate probability distributions for processing plant responses based on geometallurgical material properties and operating modes.
Implemented a metaheuristic search algorithm guided by an online machine learning model to rank and evaluate scheduling moves efficiently on a gold mining complex dataset.
Generated operationally realistic extraction sequences adhering to physical shovel movement constraints.
Achieved higher total metal production and increased net cashflow compared to conventional regression-based processing models.
