通过对焦作、淮南等矿区掘进工作面煤壁瓦斯涌出的特点、规律的研究，得出了煤壁内瓦斯涌出排放极限深度与时间的函数关系，为采掘工作面瓦斯涌出量预测提供了具有实际意义的依据。
Through the research on the characteristics and rules of gas emission from coal seam in tunneling face in Jiaozuo and Huainan coal mines, the relationship between gas emission emission limit depth and time in coal wall is obtained, providing the prediction for gas emission in mining face The basis of a practical significance.
