摘要：

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 have more ordered microstructure estimated by mean of plotting entropy-structure complexity diagrams based on thousandfold enlarged digital images of coal surface. Coal seams with more chaotic structural arrangement possess both higher natural gas content and gas saturation in face area.
