【Abstract】 According to the characteristic of open_pit mining, two static state models about the optimization of cut_off grade in open_pit mine 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.更多还原
