Mine planning engineers perform production schedule optimization to determine the time sequence in which ore blocks should be extracted to maximize value. For mines transitioning from a surface mining method to an underground extraction method (transition mines), the production schedule optimization is complex with no applicable solutions. We present two …

In mining, deposits are divided into blocks, forming the basis for open-pit mine planning, covering production and haulage route planning. Current studies often stage optimization and lack the consideration of road capacity, leading to suboptimal solutions. A novel approach integrates production scheduling and haulage route planning through a bilevel …

Optimizing the short-term production schedules independently at each mine fails to capture the benefit of generating schedules for all the mines collaboratively resulting in sub-optimal schedules. In short-term production scheduling, there are fewer blocks and thus fewer binary decision variables as compared to the long-term production scheduling.
