Quantitative assessment of energy changes in underground coal excavations using numerical approach Open
Coal burst is caused by a dynamic and unstable release of energy within the overstressed rock mass/coal during the mining process. Although the occurrence of coal burst is a result of the complex impacts of many factors, a major component …

DESIGN COMBINED SUPPORT UNDER ARBITRARY IMPULSIVE LOADING Open
Rock bolts and cable bolts are usually considered to experience static loads under relatively low-stress conditions. However, in burst-prone conditions, support elements are subjected to dynamic loading. Therefore, it is important to under…

A New Concept to Numerically Evaluate the Performance of Yielding Support under Impulsive Loading Open
The dynamic capacity of a support system is dependent on the connectivity and compatibility of its reinforcement and surface support elements. Connectivity refers to the capacity of a system to transfer the dynamic load from an element to …

Numerical and analytical simulation of the structural behaviour of fully grouted cable bolts under impulsive loading Open
Designing reliable yielding support system to mitigate the effect of the kinetic energy in burst-prone conditions in mining and tunneling excavations is one of the challenges for geotechnical engineers. A combination of the support element…

Computing the damage and fracture energy in a coal mass based on joint density Open
Coal joints and cleats are geological discontinuities that are the most important factors that affect the mechanical responses of a coal mass under stress. The joint and coal mass interaction and the mode of failure dominate the mechanical…

Analytical Determination of Energy Release in a Coal Mass Open
In underground mining, it is not currently feasible to forecast a coal burst incident. A coal burst usually includes suddenly abrupt energy release in line with the significant deformed shape in a coal mass as well as coal ejection. The ma…

A Numerical Study of the Behaviour of Fully Grouted Cable Bolts Under Static and Dynamic Loading Open
Stability of underground excavations in mining and tunneling is one of the most significant concerns of geotechnical engineers. Rock reinforcement methods can be used to increase rock strength and minimise the displacement of unstable rock…
View article: Analysis of a potential coalburst phenomenon in different strata layers in underground coal mines
Analysis of a potential coalburst phenomenon in different strata layers in underground coal mines Open
Coalburst is referred to as the violent failure of overstressed coal, which has been recognised as one of the most critical dynamic failures in coal mines. This paper aims to analytically and numerically evaluate the energy transformation …

A Review of Uncontrolled Pillar Failures Open
Coal burst is a sudden and violent rock/coal failure that occurs in underground coal mines. It is considered to be a highly catastrophic phenomenon which can cause significant damage to mine workings and equipment as well as result in mult…
