| Abstract: |
| According to the fact that the resource status and exploration condition of Shizishan copper mine change greatly since 70’s of last century, this paper calculated the reasonable productivity range (3000~2800 tons/year) in accordance with the mine’s real resource situation, by using the taylor formula and deliverability calculation. In addition, the main decision target has determined as annual profit, production cost, labor productivity and service life. The weight coefficients have determined as 0.24932, 0.24932, 0.24932 and 0.25204 by using entropy weight method. The comprehensive analysis of effect measure showed that the production scheduling results achieves the optimal when the mine-annual output value of 3000 tons/year. On the basis of linear planning theory, the integration planning model of mining productivity has established by using minimum grade chordal deviation and objective function model. The results indicated that the new planning could meet the hoisting capacity of main shaft when the copper grade value of 0.48%, and the annual metal value of 2690 tons. |
