基于GIS的矿山开采区地质灾害易发性分区评价

GIS based zoning evaluation of geological hazard susceptibility in mining area

矿山的地质灾害易发性的研究是矿山灾害研究的重点,传统方式的灾害分区评价缺少灵活性。因此提出基于GIS的矿山开采区地质灾害易发性分区评价这一课题,利用GIS的数据导入和分析功能采集矿山开采区地质灾害易发性数据,根据灾害易发性的风险评级确定矿山灾害易发性的评估技术,最后通过计算显示地质灾害易发性分区评价结果。设计一个仿真实验,使用传统的评价方式和设计的新评价方式同时对计算机模拟灾害进行评估,新方法的评估准确性传统方式更高。

The study of mine geological hazard susceptibility is the focus of mine disaster research,and the traditional method of disaster zoning evaluation is lack of flexibility.Therefore,this paper puts forward the subject of GIS based zoning evaluation of geological disaster susceptibility in mining area,uses the data import and analysis function of GIS to collect the data of geological disaster susceptibility in mining area,determines the assessment technology of mine disaster susceptibility according to the risk rating of disaster susceptibility,and finally displays the results of zoning evaluation of geological disaster susceptibility through calculation.Design a simulation experiment,using the traditional evaluation method and the new evaluation method to evaluate the computer simulation disaster at the same time,the accuracy of the new method is higher than the traditional method.
