Direct stockpile scheduling: Mathematical formulation

Abstract: In a mining context, production scheduling's main objective is to determine the best mining sequence of blocks to achieve the largest net present value and to maximize ore reserve exploitation. Stockpiling and blending procedures may represent very helpful alternatives for mine planning to ensure the ore quality and amount required by the processing plant. In order to satisfy industrial requirements of grades and tones, reducing stockpile fluctuations may represent a very important tool especially for medium a… Show more

“…DBS also attempts to consider the operational constraints at the time of the definition of the final pit, which can be considered an advance in comparison to the traditional algorithms and may provide more practical results. For instance, Benndorf and Dimitrakopoulos (2013) developed a stochastic integer programming formulation accounting for practical mining, deviation from production targets and other aspects, Richmond (2018) proposed an open pit optimization algorithm that accounts for commodity price cycles and uncertainty, and Souza et al (2018b) proposed a formulation for scheduling taking into account stockpiling, cost and blending constraints.…”
