A Modified Schimazek’s F-abrasiveness Factor for Evaluating Abrasiveness of Andesite Rocks in Rock Sawing Process

J. Ziaei; S. Ghadernejad; A. Jafarpour; R. Mikaeil

Volume 11, Issue 2 , April 2020, , Pages 563-575


  One of the most crucial factors involved in the optimum design and cost estimation of rock sawing process is the rock abrasivity that could result in a significant cost increase. Various methods including direct and indirect tests have been introduced in order to measure rock abrasivity. The Schimazek’s ...  Read More

A Hybrid Fuzzy MCDM Approach to Determine an Optimal Block Size in Open-Pit Mine Modeling: a Case Study

J. Abdollahei Sharif; A. Jafarpour; S. Yousefi

Volume 11, Issue 2 , April 2020, , Pages 611-627


  The computer-based 3D modeling of ore bodies is one of the most important steps in the resource estimation, grade determination, and production scheduling of open-pit mines. In the modeling phase, the volume of the orebody model is required to be filled by the blocks and sub-blocks. The determination ...  Read More

Application of non-linear regression and soft computing techniques for modeling process of pollutant adsorption from industrial wastewaters

A. Aryafar; R. Mikaeil; F. Doulati Ardejani; S. Shaffiee Haghshenas; A. Jafarpour

Volume 10, Issue 2 , April 2019, , Pages 327-337


  The process of pollutant adsorption from industrial wastewaters is a multivariate problem. This process is affected by many factors including the contact time (T), pH, adsorbent weight (m), and solution concentration (ppm). The main target of this work is to model and evaluate the process of pollutant ...  Read More

Optimal production strategy of bimetallic deposits under technical and economic uncertainties using stochastic chance-constrained programming

E. Bakhtavar; A. Jafarpour; S. Yousefi

Volume 8, Issue 3 , July 2017, , Pages 475-485


  In order to catch up with reality, all the macro-decisions related to long-term mining production planning must be made simultaneously and under uncertain conditions of determinant parameters. By taking advantage of the chance-constrained programming, this paper presents a stochastic model to create ...  Read More
