Abstract: This paper used ArcGIS Engine components and C# language to develop coal mine water inrush forecast information management system and build basic function module. The system made full use of a vast amount of coal mine data, screened and systematically processed the influence factors of water inrush. Fisher prediction model was established based on those factors. In order to embed the warning model into the system, the technology of Visual C#.net with MATLAB hybrid programming was used. The system has the characteristics of fast processing speed and high performance. It realizes the operation interaction and process visualization of the prediction function. So this system can provide decision-making support for the prevention and control of mine water.
