摘　　要：合理的露天开采境界直接关系到矿山经济效益,而境界的圈定是一项非常复杂的工作。根据某矿山的开采技术条件,利用3DMine软件建立了矿体实体模型和经济模型,并进行了露天开采境界圈定,通过不断优化,得出该矿山的最优露天开采境界。选择底标高为1215 m的露天境界为最终的优化境界,考虑到露天坑底最小宽度及台阶坡度影响,选择1245 m为最低平台高度。The reasonable delineation of open-pit mining boundaries is directly related to the economic benefits of a mine,and the process of boundary delineation is highly complex.Based on the mining technical conditions of a mine,the 3DMine software was utilized to establish solid models of the ore body and economic models,and the delineation of open-pit mining boundaries was conducted.Through continuous optimization,the optimal open-pit mining boundary for the mine was determined.The final optimized boundary was selected with a bottom elevation of 1215 m.Taking into account the influence of the minimum width of the pit bottom and bench slope.The lowest platform height was chosen as 1245 m.
