GIS与层次分析法相结合在宁东矿区煤矿可采性风险评价中的应用

    Application on the combination of GIS and AHP to workability risk assessment in the east Ningxia coal mine

    • 摘要: 本文将GIS技术与层次分析法相结合,对宁东矿区煤矿可采性进行评价。首先应用层次分析法对各影响因子指标进行权重计算。然后利用GIS对各影响指标进行提取并进行权重属性赋值。最后利用GIS的叠置分析功能对各指标层进行叠置分析,对评价结果进行空间可视化表达,并得到宁东矿区可采性安全评价分区图,为宁东矿区能源基地的规划建设、资源的安全合理开采提供依据。

       

      Abstract: This paper assessed the workability of the East Ningxia Coal Mine through the combination of GIS and AHP.Firstly,by AHP,weight of each impact factor index was calculated.Then,each impact factor index was extracted and the attribute weigh was valued by GIS.Finally,the paper analyzed each index level by the overlay analysis function of GIS,and done the space visual expression on evaluation results,and got the division figure of workability safe assessment in the East Ningxia Coal Mine.The results provided the basis for the planning and construction,and the reasonable exploitation of resources in the Energy Base of east Ningxia coal mine.
