利用γ+β计数率判别钻孔矿化类型方法探讨

Research of discriminating the mineralized style by using the counting rate of γ+β

从野外工作实际出发,采用数理统计方法,利用大量的矿芯γ+β编录结果与放射性取样分析结果回归出矿芯分析镭品位与γ+β计数率的相关关系公式,并将复杂公式进行简化处理,进而对γ+β编录结果进现场评价,确定放射性异常的矿化类型,大大提高了放射性取样的工作效率,取得了令人满意的实际应用效果.

From the actual fieldwork, with the mathematical statistics method, the paper makes use of large quantity of the results of the γ＋β editing and analysis of the radioactivity samplings to work out the correlative formula between the ore Ra grade and counting rate of γ＋β, and also simplifys the complex formula character to make field engineering estimate for the results of the γ＋β editing, and then ensures the mineralized style of the radioactivity abnormity, thus improves the efficiency of the radioactivity samplings, and the desired effects are obtained.
