摘要
在充分挖掘纳米比亚湖山露天铀矿山现有生产数据的基础上,研究了台阶预测模型的建模流程与估值参数取值方法。结果表明:该模型估值精度高,能提供更为精准的矿石品位分布与矿岩分界线,是后续采矿设计与区块划分的重要依据。该方法已经在湖山铀矿得到应用,起到了降低采矿损失贫化、提高经济效益的作用。
On the basis of fully excavating the existing production data of Husab open-pit uranium mine in Namibia,the modeling process and estimation parameters determination method of the predictive bench model are studied. The results show that the model has high estimation accuracy and can provide more accurate ore grade distribution and ore & waste boundary lines,which is an important basis for subsequent mining design and block cutting. This method has been applied in the Husab uranium mine,and has played an important role in reducing mining ore loss and dilution and providing economic benefits.
