摘要
针对含瓦斯煤体中瓦斯解吸问题,利用自主设计的外液侵入条件下瓦斯解吸测定装置,首次证实了外液对瓦斯解吸促进作用的存在,分析了竞位脱附和毛细静力驱动两方面原因,指出渗透剂溶液对瓦斯解吸的促进效果随着其质量分数的增加而越发明显,以及对瓦斯解吸促进作用只发生在一段时间内的规律,并结合工作面瓦斯抽采提出了提高瓦斯解吸效率的具体措施与实施途径。该研究对解决工作面瓦斯抽采与回采之间在时间上相互制约问题具有一定的参考应用价值。
It ＇ s proved independently designed between liquid and gas efficiency increases as penetrant solution only efficiency on coal face between gas extraction for the first time that external solution can promote gas desorption by using gas desorption measuring device. Two reasons of competed adsorption location and capillary static driver are analyzed. The result shows that the gas desorption the concentration of penetrant solution increases and the promotion effect of occurs in a period of time. Then specific measurements of improving gas desorption are proposed. The study can provide reference for solving the time constraint and mining on coal face.
