Abstract: We introduce a coal mine monitoring WebGIS graphics system solution based on open source technology. This system is developed based on the open source framework OpenLayers and open source server platform GeoServer, which followed the GIS standard, and implemented GIS graphic display, editing, publishing and other functions required by mine monitoring system. Through adopting the standard of GIS file format and graphic data driven method, the system has good versatility to resolve some problems in graphics system of current mine monitoring.
