摘　　要：华北型煤田广泛发育有岩溶陷落柱,岩溶陷落柱对煤矿安全生产有较大影响,特别是其突水性对煤矿安全生产威胁较大。从论述华北型煤田岩溶陷落柱顶底部剪切破坏突水模式及判据入手,分析了井下溶陷落柱突水机理。The karst sink holes are well developed in North China coal field.The karst sink holes have great influence to the mine safety production.Specially the water inrush from the karst sink holes has a large dangerous to the mine safety production.The paper stated the water inrush model of shearing failure at the karst sink hole bottom in North China coal field and analyzed the water inrush mechanism of the karst sink hole.
