英文摘要: Abstract(#br)When exploiting deep high-gas coal seams with a bursting liability, complicated rockburst disaster conditions exist because of the combined influence of stress and gas pressure. An understanding of the influence of gas on the bursting liability of coal can enable an analysis of the mechanism of the rockburst induced by gas pressure and the bursting liability of coal. Using a custom sealed pressure system, experimental studies of coal samples with a bursting liability were carried out under different gas pressure conditions. The experimental results are explained based on the coal structure, the structural effective stress, and the corrosion-damage effect of the gas on the coal. Research results show that: (1) an inverse relationship exists between gas pressure and coal...
