摘　　要：本文应用MapGIS平台DTM模型,采用分别计算上表面或下表面与基准Z平面之间体积的方法,求取体积之差,进行矿山储量评估;与平行断面法储量计算结果对比,DTM模型计算精度更高。Using the DEM model on the MapGIS platform, the paper introduces the assessment of reserves in mines by respectively calculating the volumes between the upper or lower surface and the Z datum plane to obtain the difference of the volumes. Compared with the results of the parallel section calculation method, the DTM model shows a higher accuracy.
