以大红山铜矿尾砂为试验原料，将其筛分为四个粒级，分别配置成不同浓度砂浆进行沉降试验，结果表明Richardson and Zaki 经验公式计算值与试验值存在较大偏差。对试验数据进行分析，回归出了沉降公式。回归公式计算结果较理想，与试验值误差较小。但对于粒径分布不均匀的尾砂沉降的计算，存在较大偏差。

As test material, Dahongshan copper mine tailings were screened four size fractions and configured with different concentrations sedimentation test , and the results indicate that there is large deviations between Richardson and Zaki empirical formula value and experimental value .Test data analysis and regression of the settlement formula was made .The calculate results by the re-gression formula were ideal and the experimental error is small .But for the calculation of settlement of uneven size particle tailings , there is a large deviation .
