摘要
随着计算机技术的发展及数字矿山的提出,三维可视化矿床模拟技术和露天开采境界优化方法的结合使其工序更为简化,并能获得良好的动态效果。本文以某磷矿为研究对象,借助3DMINE矿业工程软件建立了该露天矿山四采区的三维实体模型,直观地反映了矿床与工程实体的形态及其空间分布关系。针对所建的矿体模型进行了品位估值、储量计算等工作,并基于Lerchs-Grossmann优化方法(L-G法)对该矿进行露天境界优化研究,参照采矿手册及工程经验,确定合理的露天境界优化参数,得出了该矿山四采区露天开采的最优经济境界。结果可用来指导该矿山前期的资源开发和投资决策,并为后期安排生产计划和实时调度控制提供可靠的依据。通过研究,总结出了露天境界优化过程中应用的主要技术和方法。
With the development of computer technology and issue of digital mine,the perfect combination of the three dimensional visualization ore deposit simulation technique and open pit limit optimization methods makes its working procedure simple,and a good dynamic effect may be obtained.Taking a phosphate ore as an example,3D solid model of this 4th mining area is established by adopting the 3DMINE software system.It can reflect a more precise and entity model shape of deposit and working face with its distributing relationship imaging at the established ore body model the works of the grade estimation reserve calculation and so on.The study on the open pit boundary optimization of the phosphate mine is implemented based on Lerchs-Grossman optimization method to determine reasonable open pit boundary optimization parameters through referring to mining handbook and project experience,then a superior and economical open pit boundary of the mine is finally achieved.The results can be used to guide the resource development and investment decisions of the mine in earlier period and also provide a reliable basis for the arrangement of production plan and the real-time dispatch control in the later period.Through study,the main techniques and method applied in open-pit boundary optimization are summarized.
