摘　　要：针对矿山开采过程中所揭露的"陷落柱"突水致灾问题,以淮南煤田为对象,从沉积史、构造史、古岩溶形成条件以及地下水流作用等方面分析其形成与演化过程,探讨了在淮南煤田南部与中部水文地质单元中陷落柱的成因模式,并从地下水流动系统、古地貌与构造控水规律、综合地质勘探、地下水动态等方面进行综合预测,为矿山深部灰岩水害防治提供一定的指导。As for the hazard caused by karst water inrush during mining deeply,this paper discusses Karst Collapse Column（called KCC）about formation and evolution,and especially,according to geological background which includes the sedimentary history,tectonic history,the development of the ancient karst and interaction between ground water and rock,discusses formed models in southern and central hydrogeological units.Finally,with the groundwater flow system,palaeo-geomorphology and tectonic controlling ground water,comprehensive geological exploration,and groundwater dynamics,the comprehensive prediction methods have been considered,which has important guidance for further studying＂KCC＂forming process,and for how to prevent and control water disasters from KCC.
