基于Arcgis和Google earth的矿区水文地质评价研究

Hydrogeological evaluation of mining area based on Arcgis and Google earth

为更加准确针对矿区水文地质情况进行分析,利用Arcgis水文分析工具和Google earth软件分别圈定无高精度地形图。采用单因子指数法评价得知矿区地下水中Mn均超标。经分析超标原因是河谷平原地貌地层中含锰等金属元素,在腐殖酸作用下,锰元素从矿石中析出所导致。

In order to analyze the hydrogeological situation of the mining area more accurately,the Arcgis hydrological analysis tool and Google Earth software were used to delineate the non high precision topographic map.Single factor index method was used to evaluate the Mn of underground water in mining area.The reason for exceeding the standard is that manganese and other metal elements are found in the geomorphic strata of the river valley plain,and the manganese element is precipitated from the ore under the action of humic acid.
