通风状态变化(指通风绝对压力和风量的变化)会引起矿井瓦斯涌出量变化,已成为众所周知的事实。但是,它们之间的真正关系,至今仍在争论。弄清这个问题,不仅可以澄清目前在通风与瓦斯关系方面的模糊认识,而且还将给矿井选择合理的通风方式,确定反风风量和系统,为工作面合理风量的选定,以及今后矿井通风管理自动化等提供科学的根据。
It has become a well-known fact that the change of ventilation state (referring to the change of absolute pressure of ventilation and the change of air volume) will cause the gas emission of mine to change. However, the true relationship between them is still under debate. To clarify this issue can not only clarify the current vague understanding of the relationship between ventilation and gas, but also to the mine to choose a reasonable ventilation, air flow and the system to determine the appropriate choice of face air flow, and mine ventilation in the future Management automation to provide scientific basis.
