Abstract null null This study presents a novel constitutive model to characterise the mechanical behaviour of cable bolts under axial loading and subjected to different boundary conditions including constant confining pressure and constant normal stiffness. Such a model is developed based on the modified Mohr-Coulomb failure criterion as well as a newly proposed non-linear dilation formulae for the development of governing equations. The cone shaped failure mode of grout due to the axial movemen...

Abstract null null Permeability is arguably the most important parameter in gas pre-drainage and production practices in coal mining and coal seam gas industries. In fractured coal seams, permeability can significantly vary both laterally and vertically. Knowing the vertical variation of permeability in relatively thick coal seams is important in optimizing inseam pre-drainage design in underground coal mining and improving reservoir management and completion design efficiency in the coal seam g...

Abstract An analytical model is developed to simulate the load-displacement performance of rock bolts under axial loading based on Modified Continuously Yielding Criterion. Such a model accounts for various surface geometries of rock bolt as well as the various confining pressures at the rock bolt to the grout interface which play significant roles in the behaviour of grouted rock bolts under axial loading. Majority of the defined parameters in the model can be measured within the laboratory env...

Abstract Borehole breakout initiation stress is critical for mining and geotechnical engineering as it indicates horizontal stress magnitudes and rock quality in a specific layer. This stress can be significantly intensified under laboratory conditions where the borehole size is small, although the specimen sizes in previous studies varied. This may result in inaccurate experimental results as the sample itself is affected by the scale effect. In this paper, two series of normal compression test...

The effective stress coefficient (ESC) is a key parameter in the linear poroelastic effective stress formulation. In fluid-bearing porous media, the effective stress is the difference between total stress and a fraction of the pore fluid pressure controlled by the ESC. The ESC is either measured in the laboratory or estimated by empirical models using field data. Among different techniques, sonic velocity measurements are widely used to estimate the ESC. The structure of coal, however, has some ...

In general, crack monitoring of coal mining conveyor belt is carried out by simple visual inspections that are found to be inefficient due to being quite labor-intensive and for providing inaccurate health conditions of the conveyor belt. In this article, we propose a robust and low-cost passive ultrahigh-frequency (UHF)-based radio frequency identification (RFID) crack sensing system, which allows the processing and detection of the presence of crack from the sensors’ data in real time. A graph...

This paper proposes the design of an Ultra High- frequency (UHF) based passive radio frequency identification (RFID) passive tag-sensor to monitor the structural crack of a coal mining conveyor belt. A detailed comparative analysis is also conducted on the effects of varying crack orientations and widths. However, it is a challenging task, since the conveyor belt is constructed from specific non-conductive multilayered materials with different dielectric properties. To illustrate the application...

Cracking in asphalt occurs mainly due to repeated traffic loadings and temperature fluctuations. To prevent propagating cracks and to reduce unwanted rehabilitation and maintenance costs, understanding crack characteristics of an asphalt mix is of critical importance in many pavement designs. Using the indirect tensile splitting test, also known as the IDT method, this study aims to evaluate the crack propagation pattern in several asphalt mixes with the help of high-speed photography techniques...

Abstract Many experimental studies have been carried out to characterise the mechanical performance of cable bolts under axial or shear loading. The common limitation in all these studies is that only single-variate descriptive analysis was included leading to an insufficient understanding of interactive influences of a range of parameters on the mechanical performance of cable bolt. Also, defining a reasonable number of experiments for the testing program that includes wide range of parameters ...
