摘要
针对现行经济合理剥采比应用于露天矿末期延深扩帮境界确定的不足，介绍了动态经济分析方法，提出了延伸扩帮境界确定中更为合理的经济合理剥采比。
In view of the deficiency in applying the current economically rational stripping ratio to the determinatation of the extension and expansion boundry ni the late period of open pit mines,a dynamic economical analysis method is presented and a more economically rational stripping ratio for determining the extension and expansion boundry is suggested.
