摘　　要：为了对突出煤层瓦斯解吸初期的影响因素进行研究,采用实验室模拟测试的方法,对影响突出煤层瓦斯解吸的吸附平衡压力、煤样粒径、解吸时间、破坏类型等主要外部因素进行了考察,结果表明:在瓦斯解吸初期阶段,吸附平衡压力越大、粒径越小、破坏类型越严重,解吸初期阶段相同时间段内瓦斯解吸量越大;在任何条件下,瓦斯解吸量与时间的关系为单调增函数,即时间越长,解吸量愈大。To influence factors on early prominent seam gas desorption studies,laboratory simulation tests using the method of projecting the impact of coal seam gas adsorption and desorption equilibrium pressure, coal particle size, desorption time, damage type, etc. The main external factors were investigated, the results show that adsorption equilibrium greater the pressure in the early stages of gas de- sorption,the smaller the particle size, the more serious type of damage, the greater the initial stages of the same period of the desorption gas desorption; the relationship between the amount of gas desorption time monotonously increasing function under any conditions, namely the longer the greater desorption.
