过去廿多年来,用动态规划的方法成功地求解露天矿真正最优境界是有限的,这种方法取决于矿化沿走向的均匀性等矿体的性质。一般说,该类方法得不出真正的三维最优解,它们的实际功能在于给最优露天矿轮廓“划界”。勒奇斯(Lerchs)、格罗斯曼(Gros--sman)的最优横剖面法和约翰逊-夏普 Over the past two decades, it has been limited to successfully solve the true optimum of open-pit mines by means of dynamic programming, which depends on the nature of ore bodies such as the homogeneity of mineralization along the strike. Generally speaking, this kind of method can not get a true three-dimensional optimal solution, and their actual function is to “demarcate” the optimal open-pit mine profile.
