摘　　要：为了对闭坑后的阜新露天矿进行综合整治和利用,需要详细了解露天矿矿坑的地表特征,提出了利用露天矿地形图数据,提取高程点和等高线数据作为构建露天矿DEM的主要原始数据,以等高线、露天矿的台阶坎线为约束条件,生成露天矿精细DEM的方法。通过对建立的DEM模型进行地表分析,可实现了露天矿的水文分析、矿坑的坡度、坡向分布分析,为露天矿的土地利用、边坡治理和露天矿整体利用规划提供基础数据。The ground characteristics of the open-pit must be investigated in detail to undertake a comprehensive renovation and utilization to the closed Haizhou Open-pit.A method is put toward to establish refined EDM of open-pit here that the data of point elevations and contour lines are extracted as the principal data to construct the open-pit EDM by using of the topographic map data in the open-pit.The hydrological analysis,the slope of the pit and slope direction distribution analysis of the open-pit are realized by means of the ground surface analysis of the established EDM model,in which the fundamental data are provide:for land use,slope treatment and the whole utilization planning of the open-pit.
