Ventilation Parameters Optimization Control on the Goaf Gas Emission

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.
