Assessment of Slope Stability and Its Remedies in Palampur, Himachal Pradesh

Alankrit Walia; Amrit Kumar Roy

Volume 13, Issue 3 , July 2022, , Pages 767-780


  The complex geography of the Himalayan mountain range, along with the natural circumstances that already exist and the ways in which people have influenced and intervened in the region- makes various regions of the range vulnerable to slope instability. The slope stability of the area that is the subject ...  Read More

Cavability Assessment of Rock Mass in Block Caving Mining Method based on Numerical Simulation and Response Surface Methodology

B. Alipenhani; A. Majdi; H. Bakhshandeh Amnieh

Volume 13, Issue 2 , April 2022, , Pages 579-606


  The present work aims at implementing Response Surface Methodology (RSM) in order to generate a statistical model for Minimum Required Caving Span (MRCS) and estimate both the individual and mutual effects of the rock mass parameters on rock mass cavability. The adequate required data is obtained from ...  Read More

Support Analysis of Main Tunnels in Tabas Mechanized Parvadeh Mine at Intersection with Coal Seam

F. Abbasi; M.H. Khosravi; A. Jafari; Ali Bashari; B. Alipenhani

Volume 12, Issue 3 , July 2021, , Pages 711-724


  The instability of the roof and walls of the tunnels excavated in coal mines has always attracted the attention of the miners and experts in this field. In this work, the instability of the main tunnels of the mechanized Parvadeh coal mine in Tabas, Iran, at the intersection with coal seam is studied. ...  Read More

Analysis of Grinding and Chipping Processes beneath Disc Cutters of Hard Rock Tunnel Boring Machines (Case study: Uma-Oya water Conveyance Tunnel, SriLanka)

Seyed M. Pourhashemi; K. Ahangari; J. Hassanpour; Seyed M. Eftekhari

Volume 12, Issue 1 , January 2021, , Pages 281-297


  Mechanized tunneling in rocks is based on fracture propagation and rock fragmentation under disc cutters. Rock chipping is an efficient kind of fragmentation process, while the grinding process may occur under special conditions. The cutter-head penetration is an appropriate parameter involved in order ...  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


  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

Numerical Modeling of Rock Slopes with a Potential of Block-Flexural Toppling Failure

H. Sarfaraz; M. Amini

Volume 11, Issue 1 , January 2020, , Pages 247-259


  One of the most important instabilities of rock slopes is toppling failure. Among the types of toppling failure, block-flexural failures are more common instability which occurs in nature. In this failure, some rock blocks break because of tensile stresses, and some overturn under their weights, and ...  Read More

Numerical analysis of slide-head-toppling failure

H. Sarfaraz; M. H. Khosravi; M. Amini

Volume 10, Issue 4 , October 2019, , Pages 1001-1011


  In layered and blocky rock slopes, toppling failure is a common mode of instability that may occur in mining engineering. If this type of slope failure occurs as a consequence of another type of failure, it is referred to as the secondary toppling failure. “Slide-head-toppling” is a type ...  Read More

Effect of large blocks position on stability analysis of block-in-matrix slopes

E. Khorasani; M. Amini; M. F. Hossaini

Volume 10, Issue 2 , April 2019, , Pages 465-477


  Bimrocks are complex geomaterials that are defined as mixtures of rocks composed of geotechnically significant blocks within a matrix of finer texture. Bimslopes are made from bimrocks and are usually seen in weathered and shallow environments. Some characteristics of blocks affecting the strength of ...  Read More

Numerical modeling of hydraulic fracturing in carbonate rocks of Bangestan reservoir

A. Akrami; M. Hosseini; H. Sodeifi

Volume 9, Issue 1 , January 2018, , Pages 117-126


  Hydraulic fracturing is used in the oil industry in order to increase the index of production and processing in the wells whose efficiencies have been dropped due to a long-term harvest or the rocks around the wells are of low permeability. Since the hydraulic fracturing operation is costly, it is of ...  Read More

Numerical assessment of influence of confining stress on Kaiser effect using distinct element method

M. Nikkhah

Volume 8, Issue 2 , April 2017, , Pages 215-226


  Nowadays acoustic emission (AE) testing based on the Kaiser Effect (KE) is increasingly used to estimate the in-situ stress in laboratories. In this work, this effect is assessed on cylindrical specimens in numerical simulations of the cyclic loadings including loading, unloading, and re-loading cycles ...  Read More
