摘　　要：针对深埋矿山开采岩溶通道的突水致灾问题,依据近年淮南潘谢矿区揭露资料,讨论了该区岩溶类"地质异常体"特征;在分析宏观地质背景基础上,从沉积史、构造史、古岩溶发育史及地下水流作用等方面追踪其演变过程;通过分析古地貌与矿区不同深度放水试验水文地质特征,间接分析深埋条件下的古岩溶信息,并预测潘谢矿区岩溶类"地质异常体"分布位置,从而为煤炭开采过程中的灰岩水害防治提供参考。Aiming atthe hazards caused by water inrush from karst passages during deep mining, this paper discusses the characteristics of the geologic abnormal bodies (called GAD) according to recent detection data in Panxie mine. And also based on the analysis of macroscopic geological background, from the sedimentary history, tectonic history, development of the ancient karst and interaction of ground water, GAD evolution process has been deduced. Through the analysis of the ancient landform and hydrogeological characteristics of dewatering test in different depth, some important karst information is obtained indirectly. The distribution of GAD is predicted, which can provide a valuable reference for how to prevent and control karst water disasters during deep mining.
