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

Rock Mechanics
Effect of temperature as well as heating and cooling cycles on rock properties

M. Hosseini

Volume 8, Issue 4 , October 2017, , Pages 631-644

https://doi.org/10.22044/jme.2017.971

Abstract
  Temperature has a significant role in many actions performed on rocks. An example would be the effect of temperature on rocks in the burial of nuclear waste, geothermal energy extraction, deep oil well drilling, and fires in tunnels. In addition, due to diurnal/nocturnal as well as seasonal temperature ...  Read More

Development of a site-specific regression model for assessment of road-header cutting performance of Tabas coal mine based on rock properties

E. Ghasemi

Volume 8, Issue 4 , October 2017, , Pages 663-672

https://doi.org/10.22044/jme.2017.955

Abstract
  In underground excavation, where the road-headers are employed, a precise prediction of the road-header performance has a vital role in the economy of the project. In this paper, a new model is developed for prediction of the road-header performance using the non-linear multivariate regression analysis. ...  Read More

A state-of-the-art review of mechanical rock excavation technologies

A. Ramezanzadeh; M. Hood

Volume 1, Number 1 , January 2010

https://doi.org/10.22044/jme.2010.4

Abstract
  The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical ...  Read More
