Risk Evaluation of Geology Hazard Based on GIS in the 26th Shuangjingzi Iron Mine in Hami, Xinjiang

The bred and the occurrence of geology hazard have brought about tremendous destroy and loss in the social progress and economic development,and the hazard factor is diverse,and the spaced ifference is notable.Therefore,it is probable to use GIS,the latest technology means for space analyzing,to determine the geological hazard evaluation of the space problem.The author relied on arid and semi-aridregions—the 26th Shuangjingzi metaliron,in Hami City,Xinjiang,as the study area,combining qualitative with quantitative risk analysis to the collapse,land slides,debris flows,ground subsidence and cracks,settlement,the sixmajor disasters,making full use of the calculation and spatial analysis function of GIS,and studying the potential disaster zone of stacking factor analysis,and making adistrict map of geological hazard assessment about the study area finally.The map describes the potential danger area under the existing natural conditions and human activities project.The study results offer avaluable basis for reflecting the overall disaster,identifying disaster reduction objectives,optimizing defen sive measures, and making scientific and mitigation decisions.
