摘　　要：为确定黄金矿山的边际品位及合理生产规模,建立了矿山不同边际品位在不同生产规模的财务净现值计算模型,计算结果体现为在不同边际品位和生产规模条件下的财务净现值矩阵。运用计算机模拟技术,在二维坐标系中绘制财务净现值等高线图。给出了选择NPV最大的矿山开采规模和边际品位的实施方案。To determine the marginal grade of gold mines and reasonable production scale,it sets up the financial net present value calculation model with different cut-off grade in different mining production scale. The calculation results show the financial net present value matrix of different cut-off grade and different scale of production. Using computer simulation technology,it draws the financial net present value contour map in 2D coordinate system. According to the efficiency of mineral resources and the economic benefit of enterprises,this method can choose the optimization implementation of the scheme.
