1. Adaptive multi-size block modeling for mineral resources and ore reserves evaluation
Articles in Press, Accepted Manuscript, Available Online from 14 April 2021
Abstract
The key input parameters for mine planning and all subsequent mining activities is based on the block models. The block size should take into account for the geological heterogeneity ... Read More
2. An Optimum Selection of Simulated Geological Models by Multi-Point Geostatistics and Multi-Criteria Decision-Making Approaches; a Case Study in Sungun Porphyry-Cu deposit, Iran
Volume 11, Issue 2 , Spring 2020, , Pages 481-503
Abstract
An accurate modeling of sophisticated geological units has a substantial impact on designing a mine extraction plan. Geostatistical simulation approaches, via defining a variogram model ... Read More
3. Geostatistical and multi-fractal modeling of geological and geophysical characteristics in Ghalandar Skarn-Porphyry Cu Deposit, Iran
Volume 10, Issue 4 , Autumn 2019, , Pages 1061-1081
Abstract
This work aims at figuring out the spatial relationships between the geophysical and geological models in a case study pertaining to copper-sulfide mineralization through an integrated ... Read More
4. Assessment of an ore body internal dilution based on multivariate geostatistical simulation using exploratory drill hole data
Volume 10, Issue 1 , Winter 2019, , Pages 271-286
Abstract
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 ... Read More
5. Investigation of linear and non-linear estimation methods in highly-skewed gold distribution
Volume 9, Issue 4 , Autumn 2018, , Pages 967-979
Abstract
The purpose of this work is to compare the linear and non-linear kriging methods in the mineral resource estimation of the Qolqoleh gold deposit in Saqqez, NW Iran. Considering the ... Read More
6. Spatial modelling of zonality elements based on compositional nature of geochemical data using geostatistical approach: a case study of Baghqloom area, Iran
Volume 9, Issue 1 , Winter 2018, , Pages 153-167
Abstract
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 ... Read More
7. Estimation of groundwater inflow situation using fuzzy logic: a case study (Beheshtabad water conveying tunnel, Iran)
Volume 7, Issue 2 , Summer 2016, , Pages 229-238
Abstract
Water inflow is one of the most important challenges in the underground excavations. In addition to inducing working conditions and environmental problems, it decreases the stability ... Read More
8. Geostatistical simulation of dyke systems in Sungun porphyry copper deposit, Iran
Volume 6, Issue 1 , Winter 2015, , Pages 1-10
Abstract
Post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. Sungun, NW Iran, is one of the porphyry copper deposits, in which dyke intrusions ... Read More
9. On the reduction of the ordinary kriging smoothing effect
