摘　　要：湘中地区碳酸盐岩广泛分布,其中岩溶的发育受岩性、地貌、水文、构造运动等诸多因素的控制,主要分布在地下水排泄区,给煤炭资源的开发带来了严重水患。针对恩口煤矿水害问题,笔者在翔实的野外调查基础上,通过分析矿区水文地质条件、矿井水文地质特征;总结以往矿山防治水经验和教训;探讨今后老采区复采的防治水害方向和重点;认为壶天河的山口冲段、小碧河的西坪段、涟水河的杨家冲段等为重点防区,对河床铺底强度不可靠的部位应该重新加强铺底。The carbonate rock is widely distributed in the central of Hunan. The karst of this kind of rock is mainly distributed in the discharge area of groundwater, because its development is controlled by lithology, physiognomy, hydrogeology and tectonic movement. This situation brings severe water hazards to coal resource exploitation. Aimed at the water hazards of Enkou Coal Mine, based on lots of field investigation and the analysis of hydrogeologieal condition and hydrogeologie feature in this mine, the experience and lessons in control of water hazards in mine are summarized ; and the emphasis and direction on control of water hazards during back mining in old mining area is probed into. It is considered that the Shankou Section of Hutian River, the Xiping Section of Xiaobi River and Yangjiaehong Section of Lianshui River are the important sections to control water hazards, and where the riverbed is not strong should be strengthened.
