摘要
针对煤炭采样中最大允许偏倚(B)值的研究现状及其问题进行了分析,并结合实验探讨了神华煤炭机械化采样最大允许偏倚的参考值,指出测定10%最大(最小)粒度被排斥时的偏倚能够用于确定机械化采样最大允许偏倚值的大小。
Aiming at the Maximum tolerable bias value （B） for mechanized sampling, its research status and problems were analyzed in this paper. Additionally, the reference value of the maximum tolerable bias value which was used for mechanical sampling of Shenhua coal was also discussed. It was indicated that the bias when thel0% maximum （minimum） of particles （based on the measure of particle size） were rejected could be used to determine the maximum tolerable bias value for mechanical sampling.
