Geological Hazard Risk Assessment In Mining Area Based on GIS

Due to much uncertainty of geological hazards occurrence, the integrated approach of multi-parameter indicators is accepted in regional geological hazards assessment. Based on GIS, the paper chooses Shanxi province of Datong City as the research target. On the basis of investigation on the Datong spot and research at the mine geological environment has got lots of first hand data for the paper. By the fact that analysis to mainly influencing factor of Geological Hazard studies, finding out that the main mining Geological Hazard problem of Datong District is that coal mining land collapse. Based on GIS and statistical analysis of the geological hazard evaluation model of geological disasters, making hierarchies of the degree of danger.
