    • A continuous framework for open pit mine planning 
      Álvarez Daziano, Felipe; Amaya Arriagada, Jorge; Griewank, Andreas; Strogies, Nikolai (Springer-Verlag, 2011)
      This paper proposes a new mathematical framework for the open pit mine planning problem, based on continuous functional analysis. The main challenge for engineers is to determine a sequence of nested profiles maximizing ...
    • A framework for adaptive open-pit mining planning under geological uncertainty 
      Lagos, Tomás; Armstrong, Margaret; Homem-de-Mello, Tito; Lagos, Guido; Sauré Valenzuela, Denis (Springer, 2020)
      Mine planning optimization aims at maximizing the profit obtained from extracting valuable ore. Beyond its theoretical complexity-the open-pit mining problem with capacity constraints reduces to a knapsack problem with ...
    • Aggregation heuristic for the open-pit block scheduling problem 
      Jélvez, Enrique; Morales, Nelson; Nancel Penard, Pierre; Peypouquet, Juan; Reyes, Patricio (Elsevier, 2016)
      In order to establish a production plan, an open-pit mine is partitioned into a three-dimensional array of blocks. The order in which blocks are extracted and processed has a dramatic impact on the economic value of the ...
    • Antithetic random fields applied to mine planning under uncertainty 
      Nelis, Gonzalo; Ortiz, Julian; Morales, Nelson (Elsevier Ltd, 2018)
      Traditional practice in mine planning often relies on estimation techniques that fail to account for the intrinsicuncertainty of geology and grades, which may have significant consequences in the mine operation. Dealing ...
    • Application of optimized models through direct block scheduling in traditional mine planning 
      Campos, P. H. A; Arroyo, C. E.; Morales, N. (Southern African INST. Mining Metallurgy, 2018-04)
      Many papers have been published by the scientific community on the development of techniques that use direct block scheduling (DBS) to solve open pit production scheduling problems, and have compared the results obtained ...
    • Feasibility and cost minimisation for a lithium extraction problem 
      Bosch, P.; Contreras, J. P.; Munizaga Rosas, J. (Elsevier, 2020)
      In this paper we address the problem of allocating extraction pumps to wells, when exploiting lithium rich brines, as part of the production of lithium salts. The problem of choosing the location of extraction wells is ...
    • Incorporation of geometallurgical attributes and geological uncertainty into long-term open-pit mine planning 
      Morales, Nelson; Seguel, Sebastián; Cáceres, Alejandro; Jélvez, Enrique; Alarcón, Maximiliano (MDPI AG, 2019)
      © 2019 by the authors. Licensee MDPI, Basel, Switzerland.Long-term open-pit mine planning is a critical stage of a mining project that seeks to establish the best strategy for extracting mineral resources, based on the ...
    • Optimum ramp design in open pit mines 
      Yarmuch Guzmán, Juan; Brazil, Marcus; Rubinstein, Hyam; Thomas, Doreen A. (Elsevier, 2020)
      The problem studied in this paper is that of designing the optimal open pit haulage ramp that, for a given ramp width and a maximum ramp gradient, connects two points of the mine, minimising construction and operational ...
