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。
Based on the analysis of the characteristics of Voronoi diagram and its generation algorithm, a new method is proposed to solve the problem of traditional mineral reserves calculation method. The method is based on the Voronoi diagram of the set of drilling plane points. Using the Voronoi polygon’s sphere of influence properties, it is possible to calculate the volume and mineral reserves in any area. The system interface and calculation examples in Delphi programming are given. The prospect of mineral grade and economic admissibility analysis based on Voronoi body of drilling 3D point set is discussed.
