Volume 13, Issue 4 , October 2022, , Pages 973-987

https://doi.org/10.22044/jme.2022.12294.2231

Abstract
  The major factors affecting tunnel stability include the ground conditions, in-situ stresses, and project-related features. In this research work, critical strain, stress reduction factor (SRF), and capacity diagrams are used for tunnel stability analysis. For this purpose, eighteen tunnel sections are ...  Read More

The Finite Difference Analysis of Empirical Tunnel Support Design in High Stress fractured rock mass Environment at the Bunji Hydropower Project, Pakistan

Hafeezur Rehman; Wahid Ali; Kausar sultan Shah; Mohd Hazizan bin Mohd Hashim; Naseer Muhammad Khan; Muhammad Ali; Muhammad Kamran; Muhammad Junaid

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

Proposing a Viable Stabilization Method for Slope in a Weak Rock Mass Environment using Numerical Modelling: a Case Study from Cut Slopes

S. Hussain; Z. Ur Rehman; N. Muhammad Khan; I. Ahmad; S. Raza; M. Tahir; A. Ullah; D. Afzal; A. Khan; M. Salman; S. Sherin

Volume 12, Issue 4 , October 2021, , Pages 929-940

https://doi.org/10.22044/jme.2021.11198.2099

Abstract
  The design of a stable slope in a rock mass environment is a quite complicated job due to the anisotropic behaviour of the rock mass. In this research work, the cut slopes at the Swat motorway in the weakest schist rock is numerically analyzed by the shear strength reduction (SSR) approach using the ...  Read More

Optimization of Process Parameters for Enhanced Up-gradation of Qilla Saifullah Copper ore through Froth Floatation Technique

M. Ibrahim; N. Mohammad; Z. Ahmad; Sh. Bacha; N. Muhammad Khan; M. Iftikhar Khan

Volume 12, Issue 3 , July 2021, , Pages 633-649

https://doi.org/10.22044/jme.2021.10796.2047

Abstract
  In this work, we focus on the up-gradation of the copper ore of Qilla Saifullah in Pakistan through the froth flotation technique. The chemical analysis of the head copper ore sample reveal the presence of 2.85% Cu, 22%  Fe2O3, 52.9% SiO2, and other minor minerals. The optimum grinding time and ...  Read More

Analysis and Forecast of Mining Accidents in Pakistan

K. Sultan Shah; I. Mithal Jiskani; N. Muhammad Shahani; H. Ur Rehman; N. Muhammad Khan; S. Hussain

Volume 11, Issue 4 , October 2020, , Pages 967-976

https://doi.org/10.22044/jme.2020.10082.1945

Abstract
  In the mining sector, the barrier to obtain an efficient safety management system is the unavailability of future information regarding the accidents. This paper aims to use the auto-regressive integrated moving average (ARIMA) model, for the first time, to evaluate the underlying causes that affect ...  Read More
