Unstable failure of gas-bearing coal-rock combination bodies: Insights from physical experiments and numerical simulations

Outburst-rockburst coupling dynamic disaster is a complicated process of the unstable failure of a gas-bearing coal-rock combination system, which remains great challenges to the safe production of coal mines. The objective of our research is to improve understanding of the mechanism of outburst-rockburst coupling dynamic disasters. To achieve this goal, a theoretical analysis of the damage in a gas-bearing coal-rock combination body coupled...
