为精确计算煤炭资源储量,建立了基于TIN模型的煤炭资源储量计算方法。通过利用ArcGIS软件,对原始的钻孔等数据构建Delaunay TIN,再由此TIN按线性内插转栅格,进行栅格数据运算和块段分布图叠加后,由分区统计技术计算每个块段的煤炭体积,最后按体积与容重之积计算储量。通过实例应用可发现,此方法与传统块段法的计算结果相比,具有明显效果。此外,本方法非常适用于无煤层底板等高线等资料仅有钻孔数据的矿产勘探期资源储量估算和村庄下资源压覆量计算。%Based on TIN model,the calculation method for coal resource reserve is built in order to calculate the coal re-source reserves precisely. By using ArcGIS software,Delaunay TIN model based on the original borehole data is built,thus TIN model is converted into grid data according to the linear interpolation. After raster data operation and block map overlay,the coal volume of each block is calculated by the partition statistical techniques. Finally,reserves are calculated by the product of volume and density. Through example application,it is found that this method has obvious effect compared with the calculation results of the traditional segment method. In addition,this method is very applicable to resource reserve estimation and resource coverage quantity calculation under village during mineral exploratory period in the case that there is only borehole data of no coal floor seat such as contour line.
