炮孔数据库Voronoi图在多金属矿损失贫化率计算的应用

矿石的损失率与矿石的贫化率是矿山企业在生产管理中最重要的两项指标.介绍了露天矿山贫化损失的计算现状和炮孔Voronoi图的原理,以3DMINE为平台,实现了炮孔数据库Voronoi图和爆区矿岩量和金属量的自动计算.在复杂多金属矿山中引入当量品位,并将炮孔数据库Voronoi图应用于复杂多金属矿山矿石损失和贫化的管理,解决了多金属矿山贫化损失计算问题,提高了矿石质量管理的效率和准确性,满足矿区生产指导的需要,同时提高矿山企业的效益.

The Application of Voronoi Diagram of Hole in Calculating Ore Loss and Dilution of Polymetallic Ore

The dilation rates and loss rates of mineral are two most important indexes in the production management of mine enterprises. In this article the authors introduced the calculation status quo of the rate of ore loss and ore dilution and the method of Voronoi diagram. The 3DMINE as the platform, has realized the hole Voronoi diagram and the calculation of the amount of ore-bearing rock and the amount of metal of the blasting area. The authors introduced the equivalent grade in a certain complex polymetallic mine, and applies Voronoi diagram of hole to the management of ore loss and dilution of polymetallic mine. This would greatly improve the efficiency and accuracy of ore quality management, meet the needs of mine production guidance and enhance the benefit of the mining enterprises.
