Abstract: Based on the hydrological dynamic monitoring information of the Donghuantuo mine，the visualization system about the hydrological dynamic monitoring information of the Donghuantuo mine was developed using the software engineering idea and the component development mode，and combining the Visual studio.net Visual development tool. This system can unified arrange，reasonably divide all of the data about the monitoring information and the mine environmental data. The system has the function of map query，three dimensional control，spatial analysis，drill management，data output，which satisfy the integration and three dimensional visualization of the mine hydrological information. And it also provide a quick reliable technical support to safe mine manufacture.

Key words: Geographic information system (GIS), Monitoring information, Hydrological warning, System development
