Abstract: The fracturing process induced by different excavation sequence under final highwall with auger mining was numerically simulated. The simulation results reproduced the effect of different excavation sequence on the fracture of coal pillar and indicated that different excavation sequence in different levels exerts great effect on the stability of coal pillars, but in the same level the effect of excavation sequence is not obvious. The study results provided theoretical basis for optimum design and excavation technology of coal pillar.
