摘　　要：本文以宁夏某地建筑用砂矿详查项目为研究背景,采用方格网法(fgwtf)建立DEM模型估算资源量,并选取块段采用垂直投影平行断面法进行校验,证实该方法估算结果可靠。通过应用实践,表明方格网法(fgwtf)适宜范围不规则矿区的资源量估算,且具有微地形控制程度高、估算过程简单可视、数据精度高、估算效率更高的优点。In this paper,taking a detailed investigation project of construction placer in Ningxia as the research background,the DEM model is established by the square grid method(fgwtf)to estimate the resources,and the vertical projection parallel section method is used for verification,which confirms that the estimation results of the method are reliable.The application practice shows that the resource quantity estimation of irregular mining area in suitable range by the square grid method(fgwtf),the method has the advantages of high degree of micro-terrain control,simple and visual estimation process,high data precision and higher estimation efficiency.
