Researches on mining subsidence disaster management GIS´s system

In order to manage the land serious damage caused by coal mining subsidence, this paper puts forward the idea of integration of coal and land information to manage mining subsidence disaster, designs the Mining Subsidence Disaster Management Information System Based on GIS, discusses the system achievement required GIS technology(Buffer analysis and Overlay analysis), subsidence prediction technology, land suitability assessment technology, etc. The developed system realizes mining subsidence prediction, housing damage prediction, land suitability assessment, etc. It provides strong technical means and data protection for leadership decision-making to guide production, as well as the solid foundation for the establishment of Digital Mine and Harmony Mine.
