遗传算法在低贫化放矿中的应用

采用无底柱分段崩落采矿法，国内外一直采用截止品位放矿法来控制出矿。低贫化放矿提高出矿品位，降低废石混入。用遗传算法确定最低贫化率，且归纳出检验矿山能否实施低贫化放矿的经验公式，在梅山铁矿实际应用中取得较好效果。

Application of Genetic Algorithm in Low Dilution Drawing

Cut-off grade method has been used to control the ore drawing in non-pillar sublevel caving mining both in and outside China. Low dilution drawing can raise the ore grade of drawing and reduce the mixed waste rock. Genetic algorithm was used to determine the lowest dilution rate and an empiric formula was induced for testing the possibility of using the low dilution drawing, which achieved good results when used in Meishan Iron Mine.
