Base on the back ground of Dafosi mine project, the key strata theory and cusp catastrophe theory was applied to analyze the minewaterinrush mechanism from roof.
How to distinguish the source of minewaterinrush exactly and quickly is not only the major content of mine hydrogeology works, but also the important foundation of mine water prevention.
能否准确快速地判别矿井突水水源，不仅是矿井水文地质工作的主要内容，而且是煤矿防治水工作的重要基础。
