Volume 13, Issue 3 , July 2022, , Pages 781-795

https://doi.org/10.22044/jme.2022.12231.2219

Abstract
  Support design is the main goal of the Q and rock mass rating (RMR) systems. An assessment of the Q and RMR system application in tunnelling involving high-stress ground conditions shows that the first system is more appropriate due to the stress reduction factor. Recently, these two systems have been ...  Read More

Numerical Stability Analysis of Undercut Slopes Evaluated by Response Surface Methodology

H. Sarfaraz; M. H. Khosravi; T. Pipatpongsa

Volume 12, Issue 1 , January 2021, , Pages 31-43

https://doi.org/10.22044/jme.2020.10199.1957

Abstract
  One of the most important tasks in designing the undercut slopes is to determine the maximum stable undercut span to which various parameters such as the shear strength of the soil and the geometrical properties of the slope are related. Based on the arching phenomenon, by undercutting a slope, the weight ...  Read More

Sensitivity Analysis of Stress and Cracking in Rock Mass Blasting using Numerical Modelling

M.A. Chamanzad; M. Nikkhah

Volume 11, Issue 4 , October 2020, , Pages 1141-1155

https://doi.org/10.22044/jme.2020.10033.1939

Abstract
  Drilling and blasting have numerous applications in the civil and mining engineering. Due to the two major components of rock masses, namely the intact rock matrix and the discontinuities, their behavior is a complicated process to be analyzed. The purpose of this work is to investigate the effects of ...  Read More

A comparison between effects of earthquake and blasting on stability of mine slopes: a case study of Chadormalu open-pit mine

R. Shafiei Ganjeh; H. Memarian; M. H. Khosravi; M. Mojarab

Volume 10, Issue 1 , January 2019, , Pages 223-240

https://doi.org/10.22044/jme.2019.7535.1607

Abstract
  Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects ...  Read More

Numerical modelling of the underground roadways in coal mines– uncertainties caused by use of empirical-based downgrading methods and in situ stresses

M. Zoorabadi

Volume 9, Issue 3 , July 2018, , Pages 593-604

https://doi.org/10.22044/jme.2018.6633.1485

Abstract
  Numerical modelling techniques are not new for mining industry and civil engineering projects anymore. These techniques have been widely used for rock engineering problems such as stability analysis and support design of roadways and tunnels, caving and subsidence prediction, and stability analysis of ...  Read More
