钻孔点集Voronoi图在矿产储量自动计算应用与研究

Application and Study of Mineral Storage Auto-calculation Based on Voronoi Diagram of Point

针对传统矿产储量计算方法的不足,在分析平面点集Voronoi图的特性基础上,提出了一种新的计算方法。该方法主要以钻孔平面点集的Voronoi图为基础,利用Voronoi多边形的势力范围特性,在VC.NET环境下编程实现了任意区域内矿产储量的自动计算,并以刘桥二矿为实例,给出了系统界面和计算实例。

To the shortcomings of traditional mineral storage calculation methods, a new algorithm is suggest, based on analysis to the features of Voronoi diagram of point, 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 automatically calculated under the environment VC. NET, and taking liuqiao NO. 2 coal mine as an example, The interface of a software system , as well as a practical case are introduced in the paper.
