Evaluation the Effect of Blast Pattern on Overbreak Area around the Miyaneh-Ardabil Railway Tunnel

Sajjad Khalili; Masoud Monjezi; Hasel Amini Khoshalan; Amir Saghat foroush

Volume 15, Issue 3 , May 2024, , Pages 1149-1160

https://doi.org/10.22044/jme.2024.13911.2591

Abstract
  Determining the appropriate blasting pattern is important to prevent any damage to the tunnel perimeter in conventional tunneling by blasting operation in hard rocks. In this research work, the LS-DYNA software and numerical finite element method (FEM) are used for simulation of the blasting process ...  Read More

Design of Loading and Transportation Fleet in Open-Pit Mines using Simulation Approach and Metaheuristic Algorithms

H. hadizadeh Ghaziania; M. Monjezi; A. Mousavi; H. Dehghani; E. Bakhtavar

Volume 12, Issue 4 , October 2021, , Pages 1177-1188

https://doi.org/10.22044/jme.2022.11450.2131

Abstract
  The production cycle in open-pit mines includes the drilling, blasting, loading, and haulage. Since loading and haulage account for a large part of the mining costs, it is very important to optimize the transport fleet from the economic viewpoint. Simulation is one of the most widely used methods in ...  Read More

Development of An Integrated Mathematical Model to Optimize Waste Rock dumping Satisfying Environmental Aspects

T. Ramezanalizadeh; M. Monjezi; A. R. Sayadi; A. Mousavinogholi

Volume 11, Issue 2 , April 2020, , Pages 577-586

https://doi.org/10.22044/jme.2020.9293.1829

Abstract
  Waste rock dumping is very important in the production planning of open-pit mines. This subject is more crucial when there is a potential of acid-forming (PAF) by waste rocks. In such a type of mines, to protect the environment, the PAF materials should be encapsulated by non-harmful rocks. Therefore, ...  Read More

A Mathematical Model to Optimize Allocation Sequence in Dispatching Problem

M. Ghobadi Samani; M. Monjezi; J. Khademi Hamidi; A. Mousavinogholi

Volume 11, Issue 1 , January 2020, , Pages 185-192

https://doi.org/10.22044/jme.2019.8721.1766

Abstract
  Truck-Shovel fleet, as the most common transportation system in open-pit mines, has a significant part of mining costs, for which optimal management can lead to substantial cost reductions. Among the available dispatch mathematical models, the multi-stage approach is well suited for allocating trucks ...  Read More

Estimation of coal seams gas content for evaluating potential use of methane drainage system in Tabas coal mine

M. Mohtasham Seyfi; J. Khademi Hamidi; M. Monjezi; A. Hosseini

Volume 9, Issue 3 , July 2018, , Pages 667-677

https://doi.org/10.22044/jme.2018.6783.1501

Abstract
  Methane gas emission, accumulation, and explosion are the most important risk factors in underground coal mines. Hence, having a knowledge of methane gas emission potential in underground coal mines is of crucial importance in preventing the explosion risk, loss of life, and property, and providing miners' ...  Read More
