Performance Evaluation of a Haul Truck Allocation Model in the Sungun Copper Mine

Mehrnaz Mohtasham; Hossein Mirzaei Nasir Abad; Farshad Rahimzadeh-Nanekaran

Articles in Press, Accepted Manuscript, Available Online from 10 April 2024


  Transportation of materials is the most cost-intensive component in open-pit mining operations. The aim of the allocation models is to manage and optimize transportation activities, leading to reduced wasted time, and ultimately, increasing profitability while reducing operational costs. Given that the ...  Read More

Performance Comparison of Particle Swarm Optimization and Genetic Algorithm for Back-analysis of Soil Layer Geotechnical Parameters

Leila Nikakhtar; Shokroallah Zare; Hossein Mirzaei

Volume 14, Issue 1 , January 2023, , Pages 217-232


  Surface settlement induced by tunneling is one of the most crucial problems in urban environments. Hence, accurate prediction of soil geotechnical properties is an important prerequisite in the minimization of it. In this research work, the amount of surface settlement is predicted using three-dimensional ...  Read More

A 3D Finite-Difference Analysis of Interaction between a Newly-Driven Large Tunnel with Twin Tunnels in Urban Areas

S. Akbari; Sh. Zare; H. Chakeri; H. Mirzaei Nasir Abad

Volume 11, Issue 3 , July 2020, , Pages 809-823


  Evaluation of the interaction between a new and the existing underground structures is one of the important problems in urban tunneling. In this work, using FLAC3D, four numerical models of single- and twin-tube tunnels in urban areas are developed, where the horizontal distance between the single- and ...  Read More

Numerical Modelling of Backfill Grouting Approaches in EPB Tunneling

L. Nikakhtar; Sh. Zare; H. Mirzaei Nasir Abad

Volume 11, Issue 1 , January 2020, , Pages 301-314


  One of the main issues involved during tunnel construction with tunnel boring machines is the tail gap grouting. This gap is between the external diameter of tunnel lining and the excavation boundary that is filled with high-pressure grouting materials. In this work, three different approaches of gap ...  Read More

Development of a goal programming model for optimization of truck allocation in open pit mines

M. Mohtasham; H. Mirzaei Nasirabad; A. Mahmoodi Markid

Volume 8, Issue 3 , July 2017, , Pages 359-371


  Truck and shovel operations comprise approximately 60% of the total operating costs in open pit mines. In order to increase productivity and reduce the cost of mining operations, it is essential to manage the equipment used with high efficiency. In this work, the chance-constrained goal programing (CCGP) ...  Read More
