运用UDEC数值模拟软件对俯仰斜开采时结构面产状对工作面煤壁稳定性的影响进行了系统研究.结果表明:结构面产状对煤壁的稳定性产生显著影响,节理面倾角不同时煤壁稳定性对工作面俯仰角变化的敏感程度也有所不同,俯斜开采有利于工作面煤壁的稳定,仰斜开采不利于工作面煤壁的稳定.
UDEC numerical simulation software was used to systematically study the influence of structural surface shape on the coal wall stability of the working face when pitching inclined mining.The results show that the occurrence of structural face has a significant effect on the stability of coal wall, The sensitivity of the stability of coal wall to the change of working face pitch angle is also different. Down-dip mining is beneficial to the stability of the coal wall of the working face, which is not conducive to the stability of the coal wall of the working face.
