A Practical Comparison between Gaussian and Direct Sequential Simulation Algorithms using a 3D Porosity Dataset

H. Sabeti; F. Moradpouri

Volume 13, Issue 2 , April 2022, , Pages 547-557


  The geo-statistical simulation algorithms for continuous spatial variables have been used widely in order to generate the statistically-honored models. There are two main algorithms doing the continuous variable simulation, Sequential Gaussian Simulation (SGS) and Direct Sequential Simulation (DSS). ...  Read More

Applying Analytical and Quantitative Criteria to Estimate Block Model Uncertainty and Mineral Reserve Classification: A Case Study: Khoshumi Uranium Deposit in Yazd

M. Taghvaeenejad; M.R. Shayestefar; P. Moarefvand

Volume 12, Issue 2 , April 2021, , Pages 425-441


  At different stages of mining, we always face a degree of uncertainty. Some of these uncertainties, such as the amount of reserve and grade of the deposit, are due to the inherent changes in the deposit and directly affect the technical and economic indicators of the deposit. On the other hand, the heavy ...  Read More

Multivariate geostatistical estimation using minimum spatial cross-correlation factors (Case study: Cubuk Andesite quarry, Ankara, Turkey)

B. Sohrabian; R. Mikaeil; R. Hasanpour; Y. Ozcelik

Volume 9, Issue 1 , January 2018, , Pages 255-275


  The quality properties of andesite (Unit Volume Weight, Uniaxial Compression Strength, Los500, etc.) are required to determine the exploitable blocks and their sequence of extraction. However, the number of samples that can be taken and analyzed is restricted, and thus the quality properties should be ...  Read More

Geostatistical simulation of dyke systems in Sungun porphyry copper deposit, Iran

Omid Asghari

Volume 6, Issue 1 , January 2015, , Pages 1-10


  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 have made ore modeling more complicated than expected. Among different kinds of dykes, two types were chosen and ...  Read More
