摘要
用多份采样法对神华准混5号煤煤堆人工分层采样的精密度进行了核验。核验结果表明，多份采样法的实际采样精密度优于GB475-2008要求的精密度。
The precision of manual stratified sampling from stockpile of Shenhua Zhunger blended coal 5# was determined through replicate sampling method. The test result showed that the practical precision was much better than the requirement in GB 475--2008.
