A Review of Energy Associated With Coal Bursts
International Journal of Mining Science and Technology, 2018 A coal burst is defined as a rapid expulsion of coal (and potentially gas) from the boundary of the roadway. Rock and coal fractures together with micro seismic vibration is a common occurrence during mining, however, it is very uncommon for coal and rock to be propelled into the roadway.

Disturbance Response Instability Theory of Rock Bursts in Coal Mines and Its Application
Geohazard Mechanics, 2023 Aiming at the rock burst prevention in coal mines, this study argue that a rock burst is the instability of the coal mass deformation system with the infinite deformation response subjected to a small disturbance, and the concepts of control, disturbance

A Semi-Quantitative Coal Burst Risk Classification System
International Journal of Mining Science and Technology, 2018 Safety is the highest priority in the mining industry as underground mining in particular poses high safety risks to its workers. In underground coal mines, coal bursts are one of the most catastrophic hazards, which involves sudden and violent dynamic ...
