The author study gas content of coal seams in the face areas in mines of SUEK-Kuzbass. It is found that gas content of coal samples from newly exposed face ranges between 2.4 and 13.5 m 3 /t and makes 32–60% of natural gas content of studied seams. The coal seams with lower gas content in face area...
