摘　　要：为了正确合理地评定煤的哈氏可磨性指数测量的不确定度,通过使用有证标准物质煤样进行煤的哈氏可磨性指数曲线标定,进而进行平行样品的测量,并对整个过程各个关键环节进行研究分析,找到了测量不确定度的主要来源,并系统地介绍了不确定度来源的各个分量的评定方法,为实际生产工作中煤的哈氏可磨性指数不确定度评定提供了参考。In order to accurately and reasonably evaluate the uncertainty of the measurement of the hardgrove grindability index of coal,a certified reference material coal sample is used to calibrate the hardgrove grindability index curve of coal,and then parallel samples are measured.The key links in the entire process are studied and analyzed,and the main sources of measurement uncertainty are identified.The evaluation methods for each component of the uncertainty sources are systematically introduced,which provides a reference for the evaluation of the uncertainty of the hardgrove grindability index of coal in actual production.
