摘　　要：焦家金矿是一座20世纪60年代发现的老矿山,随着采矿深度和力度的加大,保有资源量已经不足,在黄金价格持续走高的情况下,焦家金矿提出了开发利用低品位资源的计划。文章利用成本收益比较法计算出了焦家金矿低品位下限为1.067×10-6,并估算出了1.00×10-6～1.50×10-6范围的资源量为226.38万t(矿石量),金金属量2600.86kg,平均品位1.15×10-6,可有效地延长矿山服务年限4.5年。Jiaojia gold mine, discovered in 1960s, is an old mine. Along with increase of mining depth and intensity, ensured reserves are shortage. As gold price continually raises, Jiaojia gold mine put forward a project to exploit and use low grade ores. By self- cost and revenue comparison method, inferior limit of low grade ores is calculated as 1. 067×10^ -6. In the range of 1.00×10^-6 - 1.50×10^-6, estimated ore resources are 2. 2638 millions tons with 2600.86kg gold and average gold grade 1.15 × 10^-6. The estimated ore resources can prolong 4.5 years mining time for Jiaojia gold mine.
