Hydrochemistry on a waste disposal area of sand mining activities at Analandia, Sao Paulo State, Brazil, and their implications on the mobilization of uranium
(1998-12-01)
Groundwaters and surface waters from an area of treatment of sand for industrial purposes at Analandia municipality, nearly in the center of Sao Paulo State, Brazil, were chemically and isotopically analyzed with two aims: ...
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 ...
Evaluating loss minimization in multi-label classification via stochastic simulation using beta distribution
(Universidade Federal do Espírito SantoBRPrograma de Pós-Graduação em InformáticaUFESMestrado em Informática, 2016-05-20)
The objective of this work is to present the effectiveness and efficiency of algorithms for solving the loss minimization problem in Multi-Label Classification (MLC). We first prove that a specific case of loss minimization ...
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 ...
CFD analysis of 58 Adit main fans parallel installation for the 2015-2019 underground developments of the new level mine project
(2015)
The New Level Mine project (NLMP), the planned underground expansion of the El Teniente mine in Rancagua, Chile, is expected to reach a daily extraction rate between 137 and 180 ktpd upon achieving full capacity. Production ...

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 ...
