摘　　要：针对传统矿产储量计算的不足,在分析平面点集Delaunay-三角网的算法的基础上,提出基于钻孔点集Delaunay-三角网的算法,并以该三角网为基础,在Visual Basic环境利用组件技术,结合钻孔属性数据库,对任意区域矿产储量进行计算,该法不仅克服算术平均法误差大及其他方法难以自动实现的缺点,而且为管理部门的规划和开采设计提供重要参考信息。Considering of the shortcoming of traditional algorithms for mineral storage calculation and basing on analyzing the features of Delaunay triangulation of planar point set, a new algorithm was suggested to calculate arbitrary region mineral storage based on triangulation, using the component technology of Visual Basic and combining with the bore attribute database. The algorithm could not only overcome the disadvantages such as the bigger error of arithmetic average, and difficult to automatically realize by other methods, but also provide important reference for the administration departments for their programming and mining design.
