Determining relative block structure rating for rock erodibility evaluation in the case of non-orthogonal joint sets

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2019
The most commonly used method for assessing the hydraulic erodibility of rock is Annandale's method. This method is based on a correlation between the erosive force of flowing water and the capacity of rock resistance.

Experimental Study on Nonlinear Seepage Characteristics and Particle Size Gradation Effect of Fractured Sandstones

open access: yesAdvances in Civil Engineering, 2018
Seepage mutation of fractured rock mass is one of the main inducements of dump slide and other disasters. Pore structure is a significant factor affecting the seepage characteristics of fractured rock mass, while particle size gradation has an important ...

Upscaling of fluid flow in fractured rock masses

open access: yes, 2021
Numerical modeling of fluid flow is applied to assess hydraulic reservoir properties and their uncertainties for decades and thus proven to be an essential part of geo-resource exploration. Yet, one of its main challenges is how to properly translate flow from the pore- to the reservoir-scale - the so-called upscaling problem. For fractured reservoirs,

Study of Rock Mass Fracturing in the Sherubaynurinsky Site

open access: yesKompleksnoe Ispolzovanie Mineralnogo Syra = Complex Use of Mineral Resources
This study investigates the fracturing of the rock mass and coal-bearing strata at the Sherubaynurinsky site of the Karaganda Coal Basin, under the complex geological and geomechanical conditions characteristic of this methane-bearing sector of the basin, in order to support coalbed methane development.

Critical slowing down characteristics of acoustic emission for bolted fractured sandstone failure under stepwise loading

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Instability failure of bolted fractured rock masses is not typically observed at the beginning stage. Instead, their deformation continuously adjusts over time in response to the continuous application of a constant load, resulting in creep failure.

GRAPHICAL DETERMINATION OF THE MOST FAVOURABLE FRONT POSITION OF EXCAVATION IN RELATION TO TECTONIC FABRIC CHARACTERISTICS AND ROCK MASS STABILITY

open access: yesRudarsko-geološko-naftni Zbornik, 1989
The rock mass discontinuity, being one of the basic tectonic fabric characteristics, has been elaborated with graphical determination in relation to rock mass stability. The method enables solution of the basic elements which are important for rock slope
