一、通风方式对采区巷道瓦斯涌出的影响 研究表明,通风方式对采区巷道瓦斯涌出的重新分布有重大意义,因为通风方式予先决定了瓦斯以采空区向回采空间或回风巷的运动。因此,当采空区瓦斯涌出较大时(靠近开采层有瓦斯补给源),调整通风方式可以作为管理瓦斯涌出的一种方法。
I. Influence of Ventilation Mode on Gas Emission from Roadway in Mining Area The study shows that ventilation mode has great significance on the redistribution of gas emission from roadway in mining area because the method of ventilation determines in advance gas to go back to the recovery space or return air Lane movement. Therefore, adjusting the ventilation mode can be used as a method to manage the gas emission when the gas emission in the goaf is large (with gas supply source close to the formation).
