Abstract: Appling the technique of WebGIS to coal and gas outburst prediction has a very important value for safety production of mine.Based on the analysis of the architecture,functionality and the support environment of ArcIMS,the paper has put forward the solution of WebGIS for coal and gas outburst prediction on ArcIMS.The key points of techniques for construction the system such as system requirements,data preparation and organization,configuration of the server and the customization of the client were discussed thoroughly.The development and its application of the coal and gas outburst prediction WebGIS show that the construction scheme is practical and can be used in the process of the digital mine construction.
