摘　　要：随着浅表优质矿产资源的逐步消耗殆尽,提高资源综合利用率,合理开发利用低品位矿产资源越来越受到国家和企业重视。大红山铜矿铜铁合采方法是回收利用低品位铜和铁资源十分有效的手段。文章通过对大红山铜矿矿床赋存条件的分析,提出了大红山铜矿铜铁合采的采矿方法,同时对影响铜铁合采成败的关键问题矿柱充填工艺技术进行了多方案比选,最终选择了泵送废石充填料浆充填工艺方案,具有适用性和可行性。With gradual utilization and exhaustion of the surface high quality mineral resources, both the country and enterprises have paid more and more attention to comprehensive utilization of resources and rational utilization of low-grade mineral resources. Copper and iron commingling in Dahongshan copper mine is a very effective means of recycling low-grade copper and iron resources. Through analyzing the deposit occurrence of Dahongshan copper mine, it has proposed the copper and iron commingling method, and through multi-program comparison of pillar filling technology which is the key issue that decides the success of commingling program, it has finally chosen the scheme of pumping waste rock pulp and backfilling, which is applicable and feasible.
