| 摘 要： | 本文结合观台矿实际情况,采用数值模拟方法对煤巷锚网索支护进行分析研究,得出了不同支护参数条件下巷道围岩变形规律,以及高水平应力是导致巷道加剧变形直至破坏的主要原因,既验证了支护参数合理性,又对支护效果进行预测,为优化支护参数提供理论依据.

| Abstract: | Based on the practical situation of Guantai mine,this research used numerical simulation method to analyze and studied the coal roadway with bolt-mesh-anchor support.The transforming rule of roadway under different support parameters was gained.The results show that the high level stress is the main factor to intensify roadway to deformation,which not only verifies reasonability of support parameters,but also predicts support effect.Therefore,theory evidence will be provided for optimizing support parameters. |
