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.
