摘　　要：通过采用加工的高压吸附煤样罐现场采集新鲜原始煤样,根据不同吸附压力下的瓦斯含量研究了原煤瓦斯吸附常数,并对其进行了验证,结果表明,该方法是可靠的。试验结果表明:吸附常数a值随着水分的增加而逐渐变小,而吸附常数b随着水分的增加而逐渐增大。Using the high pressure adsorption coal samples to collect virgin coal samples from underground mine,then the Langmuir constants were calculated by adsorption contents under different adsorption pressures.And the research are verified,it shows that the method is reliable.The experimental results show that adsorption constant a decreased gradually with the increase of moisture and adsorption constant b increased with the increase of moisture adsorption constants increase gradually.

关 键 词：原煤吸附常数 吸附常数a 吸附常数b 水分
