摘要
对新冶钢矿矿体二次圈定进行了比较详细的论述，并以采场二次圈定前、后的矿石储量、矿体形态、采场贫损指标的对比，说明采场矿体二次圈定工作是矿山企业降低损失贫化率，增加矿石产量，降低生产成本，延长矿山服务年限，获得经济效益的重要途径。
This paper discourses the second delimitation on stope ore mass in Xinye Copper Mine with relative detail, and as compare with the indexes of scope dilution and loss, the shape of ore mass and the ore reserves before and after the stope second delimitation showing that the stope second dilimitation is an important way in lowering dilution. loss and production cost, increasing production and extending mine served years of mine enterprise.
