Dual-hazard control mechanism of burst-prone and spontaneous combustion coalface considering effect of retreat speed

open access: yesEnergy Reports, 2021
For longwall top coal caving coalface characterized by strong rock burst tendency and high risk of spontaneous combustion, retreat speed is one of the key factors to induce the rock burst and spontaneous combustion of residual coal in goaf.
