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 ...
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 ...
Block size selection and its impact on open-pit design and mine planning
(SOUTH AFRICAN INST MINING METALLURGY, 2006-03)
This work evaluates and characterizes the impact of the support size and mining dilution of a block model in the operation and selection of equipment at an open pit mine. An exploratory analysis and geostatistical modelling ...
Nonparametric Geostatistical Simulation of Subsurface Facies: Tools for Validating the Reproduction of, and Uncertainty in, Facies Geometry
(Springer New York LLC, 2019)
© 2018, International Association for Mathematical Geosciences.Delineation of facies in the subsurface and quantification of uncertainty in their boundaries are significant steps in mineral resource evaluation and reservoir ...
Identifying web sessions with simulated annealing
(Elsevier, 2014)
Delivery of efficient service through a web site makes it compulsory in the redesigning stage to take into
account the behavior of the users, which can be studied by means of a web log file that partially records
information ...
Evaluating crusher system location in an open pit mine using Markov chains
(Taylor and Francis, 2017)
A methodology is presented for deciding the location of a third ore crusher to be installed at Chile’s Chuquicamata copper mine. The proposed approach determines which location alternative exhibits the minimum capital and ...
Case study: Discrete element modeling of wear in mining hoppers
(Elsevier Ltd, 2019)
A discrete element method is designed to evaluate the relative wear on hoppers caused by friction during operation in an open-pit mine. The results of the model show good agreement with measurements on real industrial ...
Multivariate simulation of block-support grades at Mehdiabad deposit, Iran
(Taylor and Francis, 2017)
Recoverable mineral resources assessment has become a standard geostatistical application in the mining industry, with various geostatistical techniques currently available. This investigation aimed to improve the prediction ...
