| Abstract: | Taking maximum net present value as an optimum target and considering factors in mining, milling and metal-lurgy, a dynamic optimum method for optimizing cutoff grade of underground orebody is given. Base on this, an idea of wholly and partially optimizing the orebody is offered to instruct the long-term, medium-term and short-term mining plan-ning and production with consideration of the geometric and geological features of the orebody and various mining methods. |
