摘　　要：以某铁矿41303N.矿块为例,详细论述了中深孔剖面法在开采块段"二次圈定"储量及预测地质品位估算的步骤和方法,并与传统储量计算方法进行对比。通过实际验证,与传统储量估算方法相比,中深孔剖面法估算开采矿块"二次圈定"储量精确度更高,其品位预测具有较高的借鉴和指导意叉,并且该方法对于建设单位及采矿承包单位合理确定考核指标,加强技术管理,避免丢矿,降低贫化具有重要意义。Taking the 41303N ore block of an iron mine for example, the proeedures and ways of using medium-length hole pro）file method to estimate second termination reserves anti predict geological grade were discussed, and compared it with traditional mining block method. The praetiee proved that this method has a higher estimation accuracy and significance in grade prediction, and is of significance in delermining suitable index, strengthening lechnology management, reducing ore dilution and loss ratio for mining contract and construction unit.
