摘　　要：为了探讨岩墙在底板围岩破坏及突水中所起的作用 ,采用ADINA有限元模拟分析了工作面开采的过程。数值模拟表明 ,在底板岩墙的位置破坏纵深最大 ,因此该位置也成了底板发生突水首当其冲的地方 。For studying the effect of rock wall on the destruction of floor surrounding rock and outbursting water,analyze the full mining process with ADINA finite element simulated analysis.The results show that the destruction of the yield depth floor dike is the biggest. So it is the most possible site where is easy to happen water invasion from coal floor. We should pay great attention to it.
