水锁作用对煤体瓦斯涌出影响的研究与发展

Ｒesearch and development of water lock effect on coal gas emission

矿井工作面瓦斯超限严重影响着矿井安全生产和生产效率,现用解决该问题的方法存在局限性,不能广泛适用于所有矿井。针对该问题,采用水及含添加剂水阻碍和延缓煤体内瓦斯解吸速度,以达到降低工作面瓦斯涌出量的目的。本文通过对其抑制原理相关研究的介绍,为同类工作面瓦斯超限治理提供基础理论依据。

The safety and production efficiency of coal production are seriously affected by gas exceeding the limit in working face. Due to the limitations of solutions in use, the solutions cant be widely applicable to all mines. So water and water containing additive is used to delay or hinder gas desorption, so that reduce the gas emission in working face. Through the research on the suppression principle is introduced, pro- viding theoretical basis for the working face gas governance transfinite.
