Abstract

According to the characteristic of open_pitmining, two static state models about the optimization of cut-off grade in open-pitmine have been presented and analysed.By combining the principle of marginal analytical method with the time value factor of fund, the dynamic state model about the optimization of cut-off grade in open-pit mine and its adjustment of service life year by year are built, and the practical calculation is carried out.
