通风参数优化控制采空区瓦斯涌出

Ventilation Parameters Optimization Control on the Goaf Gas Emission

摘要: 通过对"U"型通风方式采煤工作面采空区的瓦斯涌出方式和来源的分析,探讨了通过通风参数优化控制采空区瓦斯涌出的机理,并在2101工作面进行了现场的测定和考察,确定了2101采煤工作面控制瓦斯涌出的最优风量为800～900 m³/min。

Abstract: Through Analyzing the gas emission ways and sources in "U "style ventilation model coal face goaf, the paper discusses the mechanism of goaf gas emission controlled by ventilation parameters, and filed determination and study is carried out in 2101 working face. Finally, the optimal air volume of controlling gas emission in 2101 working face is determined as 800～900 m³/min.
