摘　　要：为了顺利进行崩落法转充填法开采工作,程潮铁矿采用灰色关联分析法,依据分段留矿嗣后充填法、上向进路充填法、下向进路充填法3种优劣差别较小的备选充填采矿方案与理想方案和负理想方案的灰色关联度,构建各备选方案的灰色关联相对贴近度(GCRN),以灰色关联相对贴近度表征方案间的差距,进行采矿方法优选,得出最优方案为上向进路充填法。矿山试验段试生产情况表明,优选采矿法采场生产能力为1056t/d,损失率为7.8%,贫化率为4.8%,成本约为90元/t,满足矿山生产目标要求。For successful transition from caving method to filling method in Chengchao Iron Mine,The Grey correlation analysis method was used to optimize the alternative schemes.Three filling mining methods,with little distinction,were selected,including the sublevel shrinkage method with subsequent filling method,the upward drift filling method and the downward drift filling method.According to the grey relational degrees of alternative schemes with the ideal scheme and the negative ideal scheme,the GCRN of each scheme was established to reflect the differences of alternative schemes.Finally,the upward drift filling method was obtained as the optimal scheme.The results of trial production proved that the selected mining method could meet the mining production,with mining capacity of 105t/d,loss rate of7.8%,dilution rate of 4.8%,and the cost of 90RMB/t.
