Abstract: The moisture content of coal is an important indicator in coal analysis, and its test results are of great significance for coal benchmark conversion, calorific value calculation, storage and transportation, quality classification, and understanding of coal metamorphism. It is necessary to strictly follow national standards throughout the entire process to obtain accurate results.

Keywords: moisture test; heating and drying; sampling; sample preparation; influencing factor
