| 摘 要： | 该文在分析平面点集Voronoi图特性及其生成算法的基础上，针对传统矿产储量计算方法的不足，提出了一种新的方法。该法以钻孔平面点集的Voronoi图为基础，利用Voronoi多边形的势力范围特性，实现了任意区域内矿床体积与矿产储量的计算。并给出了以Delphi编程实现的系统界面与计算实例，讨论了基于钻孔三维点集的Voronoi体进行矿产品位与经济可采性分析的前景。

| Abstract: | Based on analysis to the features of Voronoi diagram of planar point-set and to its generating algorithm, and in consideration of the shortcomings of traditional algorithms for mineral storage calculation, a new algorithm is suggested. The new algorithm takes the Voronoi diagram of planar point-sets of drill holes as its basis. By utilizing the influence range of Voronoi polygons, the mineral storage inside any shaped region could be calculated. The interface of a software system, programmed with Delphi and SQL server, as well as a practical case are introduced in the paper. Besides, the prospect of ore grade and economical analysis based on 3D Voronoi diagram of the 3D point-set of drill holes are discussed. |
