An Experimental Study on Water Saturation Effect on Rock Cutting Force of a Chisel Pick

Hadi Bejari; Jafar Khademi Hamidi

Volume 14, Issue 2 , April 2023, , Pages 577-600

https://doi.org/10.22044/jme.2023.12606.2290

Abstract
  This work aims to investigate the effect of water saturation on cutting forces and chipping efficiency by performing a series of small-scale linear cutting tests with a chisel pick on twelve low- and medium-strength rock samples. The peak and mean cutting force acting on the chisel pick are measured ...  Read More

A Numerical Investigation of TBM Disc Cutter Life Prediction in Hard Rocks

M. Zahiri; K. Goshtasbi; J. Khademi Hamidi; K. Ahangari

Volume 11, Issue 4 , October 2020, , Pages 1095-1113

https://doi.org/10.22044/jme.2020.9933.1922

Abstract
  There is a direct relationship between the efficiency of mechanized excavation in hard rocks and that of disc cutters. Disc cutter wear is an important effective factor involved in the functionality of tunnel boring machines. Replacement of disc cutters is a time-consuming and costly activity that can ...  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
