摘要
经过对高瓦斯矿井掘进巷道中瓦斯浓度变化的研究,分析了低透气性煤层中综掘巷道内游离瓦斯与吸附瓦斯的涌出规律,以便于科学组织正规循环作业生产和矿井采掘衔接设计,为矿井安全高效生产提供一种路径。
By the study on gas concentration variation from heading tunnel in high gassy mines, the paper analyzes the emission law of free gas and absorbing gas in the low-permeability coal seam of the fully-mechanized mining tunnel. The study facilitates the connection design of the regular cycle operation and mining and provides an approach to safe and efficient production
