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 m3/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.

煤微观结构对工作面含气量的影响

笔者研究了SUEK-Kuzbass煤矿工作面区域煤层的含气量。发现新出露工作面煤样的含气量在 2.4 至 13.5 m3/t 之间，占研究煤层天然气含量的 32-60%。通过基于千倍放大的煤表面数字图像绘制熵-结构复杂度图估计工作面含气量较低的煤层具有更有序的微观结构。构造排列较杂乱的煤层具有较高的天然气含量和工作面含气饱和度。
