| 摘 要： | 在分析影响露天开采境界诸因素的基础上，采用动态经济分析的方法，综合考虑了矿石开采成本、矿石价格、露天开采强度、工作帮坡角、贴现率以及扩大境界后的露天补充投资、排土场二次倒运量、推这地下井建的时间等因素，对露天开采境界的合理确定进行了探讨。

| Abstract: | This paper investigates the potential for applying dynamic,economic and analytical methods to determining the open pit limit This has been done by analysing factors restricting the potential for open pit mining limit.The following factors will be considerd: (1)mining cost and price of ore (2)mining intensity (3)working slop angle (4)discount rate of expenses (5)quantity of secondery transportation of waste rock and additional investment of open pitting and economic implication of the postponed underground construction project,because of open pit mining limit expension |
