摘　　要：在总结华北煤田多起陷落柱突水事例及对徐淮煤田40多个矿区调研的基础上,依据陷落柱不同发育阶段的水文地质工程地质特征等,将其分为4个发育阶段:前期发育阶段、强烈发育阶段、衰退阶段和死亡阶段。通过分析陷落柱发育的不同层位,将其划分为3类,即奥灰层位之上可溶岩组、奥陶纪可溶岩组及寒武纪可溶岩组。继而,将陷落柱综合划分为12类,并总结分析了各类型陷落柱的地质特征。On the basis of summarizing many water inrush eases of collapse columns in North China coalfields and investigations on over 40 mine areas, Xuhuai coalfield, four developing phases are divided according to the hydrologic and engineering geology characteristics in different developing phases. They are prophase, intensity phase, decline phase and death phase. By analyzing the different strata where collapse columns developed in North China coalfields, three types of strata are classified： the soluble rock group above Ordovician, Ordovician soluble rock group, Cambrian soluble rock group. Consequently, 12 types of collapse columns are classified integratedly, And the geologic characteristics of each type of collapse column are analyzed and summarized.
