Rock Mechanics
Improving the P-wave velocity determination by considering the effects of joint properties in artificial rock samples

Mohammad Rezaei; Seyed Pourya Hosseini; Danial Jahed Armaghani; Manoj Khandelwal

Articles in Press, Accepted Manuscript, Available Online from 19 December 2024

https://doi.org/10.22044/jme.2024.15261.2924

Abstract
  This paper presents an experimental-statistical study investigating the influence of five joint properties: density, filling type, angle, aperture, and roughness on the longitudinal wave velocity (LWV) of concrete samples. To achieve this, each of the five properties is categorized into distinct groups ...  Read More

Studying Effects of Cooling/Lubricating Fluids, Machining Parameters, and Rock Mechanical Properties on Specific Energy in Rock Drilling Process

Shahrokh Khosravimanesh; Masoud Cheraghi Seifabad; Reza Mikaeil; Raheb Bagherpour

Volume 15, Issue 2 , April 2024, , Pages 613-636

https://doi.org/10.22044/jme.2023.13478.2491

Abstract
  Specific energy is a key indicator of drilling performance to consider in the feasibility and economic analyses of drilling projects. Any improvement in the specific energy of a drilling operation may reflect an improvement in the overall efficiency of drilling operations. This improvement can be achieved ...  Read More

Study of Effect of Cooling/Lubricating Fluids, Machining Parameters, and Rock Mechanical Properties on Penetration Rate in Rock Drilling Process

Sh. Khosravimanesh; M. Cheraghi Seifabad; R. Mikaeil; R. Bagherpour

Volume 12, Issue 3 , July 2021, , Pages 825-843

https://doi.org/10.22044/jme.2021.11017.2078

Abstract
  In most rock drilling operations, the low rate of penetration (ROP) can be primarily attributed to the presence of the cuttings produced during drilling and the thermal stresses caused by friction at the bit-rock interface, which can be exacerbated with the increasing strength, hardness, and abrasivity ...  Read More

A Correlation for Estimating LCPC Abrasivity Coefficient using Rock Properties

M. Ansari; M. Hosseini; A. R. Taleb Beydokhti

Volume 11, Issue 3 , July 2020, , Pages 799-808

https://doi.org/10.22044/jme.2020.9520.1863

Abstract
  Rock abrasivity, as one of the most important parameters affecting the rock drillability, significantly influences the drilling rate in mines. Therefore, rock abrasivity should be carefully evaluated prior to selecting and employing drilling machines. Since the tests for a rock abrasivity assessment ...  Read More

A new brittleness index for estimation of rock fracture toughness

H. R. Nejati; Seyed A. Moosavi

Volume 8, Issue 1 , January 2017, , Pages 83-91

https://doi.org/10.22044/jme.2016.579

Abstract
  Assessment of the correlation between rock brittleness and rock fracture toughness has been the subject of extensive research works in the recent years. Unfortunately, the brittleness measurement methods have not yet been standardized, and rock fracture toughness cannot be estimated satisfactorily by ...  Read More
