| 摘 要： | 为了研究向斜构造应力场对煤层巷道围岩稳定性的影响，运用Phase2软件对巷道布置在向斜构造中不同位置时的稳定性进行了数值模拟分析.分析得知巷道位于向斜轴部时较位于两翼时围岩稳定性差。对此，提出在以后布置巷道时应根据地应力的显现规律，尽量避免巷道布置在向斜轴部处。

| Abstract: | To study the effect of structural stress field on the stability of rock surrounding underground roadways, Phase2 software is 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 roadway in axis of syncline is poorer than in wings of syncline. Therefore,it is proposed that,in underground road- way configuration ,the appearance regularity of field stress should be based,with prevent roadway arranging in the axis of syneline. |
