Numerical Simulation of the Effect of Structural Stress Field on Stability of Surrounding Rock in Coal Seam Roadway

To research the effect of structural stress field on the stability of rock surrounding underground roadways, Phase2 software was used in the numerical simulation analysis of the stability of underground roadway in different location in the structural stress field. It is concluded that the stability of underground roadways in axis of syncline are poorer than in wings of syncline. Therefore, it is proposed that, in underground roadways configuration, we should base the appearance regularity of field stress, and prevent roadways arranged in the axis of syncline.
