基于Voronoi图的爆区品位和矿量计算

摘要

Based on the analysis of the characteristics of Voronoi diagram and generation algorithm in planar point set, the secondary development tool of Surpac-Tcl/Scl and the features of sphere of influence, was put forward to achieve the automatic calculation of average grade and ore quantity of blast zone based on the sampling data of blast holes. This method has been good application in a copper-molybdenum mine, finally the efficiency and accuracy of ore quality management is improved greatly.%分析了平面点集Voronoi图特性及生成算法,提出了利用Surpac矿业软件的二次开发工具--Tcl/Scl脚本语言和Voronoi图原理的势力范围特性,实现基于平面炮孔化验数据的区域平均品位和矿量的自动计算.该方法在某铜钼矿取得了很好地应用,大大提高了该矿矿石质量管理的效率和准确性.
