Application of Sequential Gaussian Conditional Simulation to Underground Mine Design Under Grade Uncertainty

F. Sotoudeh; M. Ataei; R. Kakaie; Y. Pourrahimian

Volume 11, Issue 3 , July 2020, , Pages 695-709


  In mining projects, all uncertainties associated with a project must be considered to determine the feasibility study. Grade uncertainty is one of the major components of technical uncertainty that affects the variability of the project. Geostatistical simulation, as a reliable approach, is the most ...  Read More

Characterization of rare earth elements by coupling multivariate analysis, factor analysis, and geostatistical simulation; case-study of Gazestan deposit, central Iran

F. Soltani; P. Moarefvand; F. Alinia; P. Afzal

Volume 10, Issue 4 , October 2019, , Pages 929-945


  The traditional approaches of modeling and estimation of highly skewed deposits have led to incorrect evaluations, creating challenges and risks in resource management. The low concentration of the rare earth element (REE) deposits, on one hand, and their strategic importance, on the other, enhances ...  Read More

A comprehensive benchmark between two filter-based multiple-point simulation algorithms

M. Bavand Savadkoohi; B. Tokhmechi; E. Gloaguen; A.R. Arab-Amiri

Volume 10, Issue 1 , January 2019, , Pages 139-149


  Computer graphics offer various gadgets to enhance the reconstruction of high-order statistics that are not correctly addressed by the two-point statistics approaches. Almost all the newly developed multiple-point geostatistics (MPS) algorithms, to some extent, adapt these techniques to increase the ...  Read More

Assessment of an ore body internal dilution based on multivariate geostatistical simulation using exploratory drill hole data

I. Masoumi; Gh.R. Kamali; O. Asghari

Volume 10, Issue 1 , January 2019, , Pages 271-286


  Dilution can best be defined as the proportion of waste tonnage to the total weight of ore and waste in each block. Predicting the internal dilution based on geological boundaries of waste and ore in each block can help engineers to develop more reliable long-term planning designs in mining activities. ...  Read More

Spatial modelling of zonality elements based on compositional nature of geochemical data using geostatistical approach: a case study of Baghqloom area, Iran

S. Talesh Hosseini; O. Asghari; Seyed R. Ghavami Riabi

Volume 9, Issue 1 , January 2018, , Pages 153-167


  Due to the existence of a constant sum of constraints, the geochemical data is presented as the compositional data that has a closed number system. A closed number system is a dataset that includes several variables. The summation value of variables is constant, being equal to one. By calculating the ...  Read More
