Numerical Simulation Study of Liquid-Solid Coupling of Coal Seam Water Infusion

摘要：

The liquid-solid coupling effect of coal and water was simulated by ABAQUS software in this paper. Numerical simulation results show that: during the process of coal seam water infusion, the stress field and seepage field were mutual influence and mutual restriction. The coupling of the field of stress and seepage caused the physical and mechanical properties of coal in front of the working face changed, made the micro-fissure of the coal further expansion and transfixion, weakened the strength of coal, made the coal skeleton softening and coal seam skeleton effective stress decreases. These factors promote each other and prevent coal and gas outburst effectively.
