煤矿中小型构造控制瓦斯涌出规律

Gas Emission Law Controlled by Medium and Small Structures in Coal Mines

描述了矿井中小型断层构造的特征,尤其是生产中经常出现的小于煤厚的小构造特征,把生产实践中揭露的构造资料结合瓦斯监测资料,详细分析了瓦斯涌出与构造的关系,探讨了中小断层构造控制瓦斯的规律,论述了中小断层构造与工作面瓦斯涌出的关系,为矿井安全生产及瓦斯治理提供了基础和依据。

This paper describes the characteristics of medium and small fault structures in a mine, especially the characteristics of those small fault structures with thickness less than that of coal seam during mining. Through the combination of fault structure information revealed in coal mining with gas monitoring data, the paper gives a detailed analysis on the relation of gas emission and fault structures, discusses the gas emission law controlled by medium and small fault structures and describes the relation of the medium and small fault structures and gas emission in a coal face, thus providing basis for the safe production and gas control of coal mines.
