A simulation-optimization framework for short-term underground mine production scheduling
(Springer, 2020)
Mine operations are supported by a short-term production schedule, which defines where and when mining activities are performed. However, deviations can be observed in this short-term production schedule because of several ...
Assessing the impact of geologic contact dilution in ore/waste classification in the gol-gohar iron ore mine, southeastern Iran
(MDPI, 2020)
Since the Gol-Gohar iron ore mine (GGIOM), which is located in southeastern Iran, is currently one of the biggest iron mines in this region, increasing the accuracy of its mineral resources model has become a challenge for ...
Modelagem de dados de entrada para simulação estocástica de lavra
(Escola de Minas, 2010)
Mine simulation depends on data that is both coherent and representative of the mining operation. This paper describes a methodology for modeling operational data which has been developed for mine simulation. The methodology ...
UML Profile for Mining Process: Supporting Modeling and Simulation Based on Metamodels of Activity Diagram
(Hindawi Publishing Corporation, 2014-02-04)
An UML profile describes lightweight extension mechanism to the UML by defining custom stereotypes, tagged values, and constraints. They are used to adapt UML metamodel to different platforms and domains. In this paper we ...
Simulation and optimization techniques for short-term mine production scheduling
(Universidad de Chile, 2020)
Short-term mine production schedules aim to meet goals previously defined by the long-term mine production schedule. Unfortunately, the complexity and uncertainty of a mine operation cause deviations from the short-term ...
Stochastic open-pit mine production scheduling: A case study of an iron deposit
(MDPI, 2020)
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 ...
Antithetic random fields applied to mine planning under uncertainty
(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 ...
Modelagem de dados de entrada para simulação estocástica de lavra
(Escola de Minas, 2010)
A simulação de lavra depende da utilização de dados coerentes e representativos da operação da mina. Esse trabalho propõe uma metodologia de modelagem de dados especificamente desenvolvida para simulação de lavra. A ...
