Factors influencing the anti-impact performance of a “roadway rock support” system
Frontiers in Earth Science, 2023 A mechanical model of a circular section of a tunnel roadway considering damage is established to improve the impact protection performance of the “roadway rock-support” system and provide a theoretical basis for designing coal mine impact ground ...

Investigation of Coal Burst Potential Using Numerical Modeling and Rock Burst Indices [PDF]
, 2021 Coal bursts are typically defined as a rapid failure of coal or surrounding rock producing a violent release of energy and ejection of rock particles. This phenomenon is extremely complex and dynamic, and this has made it very difficult to predict.
