Under the conditions of external solution invasion and no external solution invasion, gas desorption comparative experiments are carried out, the experiment data and curve of gas desorption are obtained, and the influence of external solution invasion upon gas desorption is analyzed. The results show that whether or not there is the external solution invasion, the higher gas pressure of coal with gas is, the larger gas natural desorption quantity is, and gas desorption is mainly concentrated on first 1h; after external solution invades, water lock effect on the coal with gas could be produced, therefore gas desorption quantity is reduced and gas release speed is slow down. Preventing gas from exceeding limit on a coal face by using water lock effect is feasible, it could be implemented through two solutions, that is, coal bed infuse solution and spraying permeable agent solution during the coal mining., authors=ZHANG Guohua^1,2, LIANG Bing², HOU Fengcai¹, BI Yewu¹, authorsList=ZHANG Guohua;LIANG Bing;HOU Fengcai;BI Yewu, authorCompany=1.

articleAbstract=针对回采工作面瓦斯超限问题,利用自主研发的外液侵入条件下瓦斯解吸实验装置,开展了有、无渗透剂溶液侵入条件下的瓦斯解吸对比实验,获得了相关实验数据和瓦斯解吸曲线,据此分析了外液侵入对瓦斯解吸的影响。结果表明,无论有无外液侵入,含瓦斯煤体所处的瓦斯压力水平越高,其瓦斯自然解吸量越大,瓦斯解吸主要集中在前1h内;在外液侵入后,能够在含瓦斯煤体中产生水锁效应,从而降低瓦斯的释放量并延缓瓦斯的释放速度;利用水锁效应防止工作面瓦斯超限具有可行性,可结合实际通过煤层注液和落煤过程中喷洒渗透剂溶液两种途径予以实施。,
