摘要
基于综合机械化采煤的规律和瓦斯运移理论,通过对端氏煤矿一次采全高某工作面的瓦斯来源及构成比例分析,把瓦斯涌出源分为煤壁的瓦斯涌出、采落煤的瓦斯涌出、采空区的瓦斯涌出和上、下邻近层的瓦斯涌出四部分。为以后瓦斯治理提供了基础数据,保证了采煤工作面的安全生产。
Based on the theory of the comprehensive mechanized coal mining and gas migration, through the analysis of the gas gushing source and proportion in the full-seam mining face of Duanshi coal mine, divide the gas source into the gas from coal wall, the gas from cutting coal, the gas from gob and the gas from adjacent seam,To provide basic data for gas management, guarantee the safe production of coal mining working face.
