In this mining method production planning PP is carried out based on the defined ultimate pit limit UPL. On the other hand, UPL is defined based on block economic values BEVs.Production planning decisions in the mining industry are affected by geological, geometallurgical, economic and operational information. However, the traditional approach to address this problem often relies on simplified models that ignore the variability and uncertainty of these parameters.

Open pits are different from underground mines and some of the major differences between the two are summarized in Table II. This means that an open pit mine can generally be started in a relatively short time while most underground mines require several years of development prior to production.Determining an optimum long term production schedule is an important part of the planning process of any open pit mine however, the associated optimization problem is demanding and hard to deal with, as it involves large datasets and multiple hard and soft constraints which makes it a large combinatorial optimization problem. In this paper a procedure has been proposed to apply a relatively ...
