VOLATILE MATTER IN PIT COALS AND ITS INFLUENCE ON GAS EMISSION IN COAL MINES

The dependence of coal metamorphism on the volatile matter yield indicator is reviewed. The volatile matter yield impact on the coal sorption capacity is reviewed. It is stated that the volatile matter yield isn’t a reliable factor of metamorphism intensity, especially for low and highly-metamorphic coal. Using the volatile matter yield indicator in regulating documents for the forecast of coal mines gas volume by the natural gas content in coal seams results in unreliable parameters of workings ventilation.

Key words: COAL, VOLATILE MATTER, COAL METAMORPHISM, METHANE RETENTION CAPACITY OF COAL, GAS CONTENT, GAS EMISSION
