摘　　要：在煤/焦炭检测中,通过对多个采样单元分析处理得到整批煤/焦炭品质使用加权计算方法进行全面探索和验证。选取不同地区的煤炭、焦炭以及矸石,分别对其全水分、水分、灰分、挥发分、全硫、发热量、氢等煤/焦炭检测指标,共172批样品进行验证,证明灰分、挥发分、全硫、发热量、氢等项目可以在以干燥基为基准的前提下进行各个基态加权计算,并通过实验验证加权计算针对不同基态下公式的应用情况。A comprehensive exploration and verification of the weighted calculation method used in coal/coke quality detection for the entire batch of coal/coke by analyzing and processing multiple sampling units.Selecting coal,coke,and gangue from different regions,a total of 172 batches of coal/coke detection indicators including total moisture,moisture,ash,volatile matter,total sulfur,calorific value,and hydrogen were verified.It was proved that ash,volatile matter,total sulfur,calorific value,and hydrogen can be weighted for each ground state based on the received basis,and the application of the weighted calculation formula for different ground states can be verified through experiments.
