Abstract: Extraction of gas from coal core was conducted using thermo-vacuum degassing. Advantages and disadvantages methods used to determine the gas composition of coal seams were explored. It is shown, that change of gas composition mixture in a wide range concentration depends on stages of degassing.

Key words: methane of coal bed coal chromatography gas composition
