从马坑铁矿看我国南方岩溶金属矿山防治水工作

我国南方金属岩溶矿山存在突水事故频发、地下水资源枯竭、岩溶塌陷等水文地质环境问题。用地下水系统理论指导岩溶金属矿山防治水工作，查明矿区岩溶水系统的边界、内部结构及系统与环境间的关系，可使水文地质工作更具方向性和目标性。利用地下水位自动监测、高精度自动示踪试验、三维可视化水文地质信息管理等新技术、新方法，查明河道渗漏、岩溶水集中径流通道等关键水文地质问题，可节省大量人力、物力，减少资金投入。

Views on Metal Mine Water Prevention and Control in South China from Makeng Iron Mine

Hydrogeological and environmental problems,such as water inrush,depletion of groundwater resources,and karst subsidence,present in metal karst mine in south China.The principle of groundwater system is used to guide the mine water prevention and control,thus identifying the boundaries of karst water system,the internal structure and the relationship between system and environment.It can make hydrogeological work more directional and objective.New technologies and methods such as automatic monitoring of groundwater level,high-precision automatic tracer test,three-dimensional visualization of hydrogeological information management are adopted to identify such key hydrogeological problems as river seepage,karst water run-off channels.Hence,lots of labors,physical resources,and funds investments can be saved.
