商品煤人工采样方法的改进
|
摘要
探讨了商品煤人工采样标准GB475-2008和ISO18283:2006在实际应用中遇到的几类问题。依照采样基本原则,提出了分段控制时间基采样法;考虑货物重量、煤质序列相关性等影响因素,给出了初级子样方差估算公式及其推导过程,并明确了国际标准中采样单元数量的计算公式和子样数目的修正公式。
This paper discusses several problems of standard methods for manual sampling of commercial coal in practical application, proposes the staged control time-basis sampling method according to the basic principle of coal sampling, describes the factors such as cargo weight and coal quality serial correlation, provides the estimation formula of primary increment variance and its derivation process, and determines the calculation formula of sampling unit number and the correction formula of increment amount in international standards.
