The determination of total moisture in coal samples of 13 mm and 6 mm shen-mixing series,quasi-mixing series and carboniferous series was carried out,GB/T 19494.3-2023《Coal Mechanized Sampling Part 3:Precision Determination and Deviation Test》and the mathematical statistics method t-test in coal analysis were used to analyze the total moisture content of different granularity,in order to explore whether the two granularity size coal sample test method can replace each other.
