Energies Within Rock Mass and the Associated Dynamic Rock Failures Open
Catastrophic dynamic rock failure is one of the most challenging problems existing in the fields of civil tunneling and mining. It occurs in complex environments of geology, stress and excavation, and there is no one set of circumstances t…

The development and implementation of design flowchart for probabilistic rock slope stability assessments: a review Open
Background Rock slope instability is a complex geotechnical issue that is affected by site-specific rock properties, geological structures, groundwater, and earthquake load conditions. Numerous studies acknowledge these aleatory uncertaint…

Numerical investigation of two typical outbursts in development headings: A case study in a Chinese coalfield Open
Numerical modelling is an effective technique to improve the understanding of outburst initiation mechanisms and to take appropriate measures to address their threats. Based on the existing two-way sequential coupling method, two typical t…

Ultimate Bearing Capacity of Weak Foundations under Coal Pillars Open
In many underground coal mines, a seam is underlain by weak floor material, and the load-carrying capacity of a pillar may be limited not by its own strength but by the bearing capacity of the floor. It has been proposed that bearing capac…

An energy-based quantitative coal burst proneness rating system for development roadways Open
Coal burst is one of the principal hazards in development panels of underground coal mines. This study develops a practical approach to quantitatively estimate coal burst proneness in development roadways. A rigorous numerical and statisti…

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 …

A review of investigations on ground support requirements in coal burst-prone mines Open
Ground support is widely implemented to mitigate dynamic rock failures in underground mines. This paper investigated the ground support requirements in burst-prone mines to mitigate the catastrophic dynamic rock failures of rock and/or coa…
