摘要
采用实验研究和方程拟合的方法,对陶一煤矿岩浆岩侵入型煤层煤样的瓦斯吸附特性进行了研究。实验研究结果表明,陶一煤矿煤层因受岩浆岩的侵入影响,煤层变质程度增高,其对瓦斯的吸附量偏低,且压力常数b出现负值,吸附曲线不能用Langmuir方程来描述,也不符合其他6类等温吸附曲线中的任何一类。
Using the method of experiments and equation simulation we studied the isothermal adsorption characteristics of methane of the coal seam that invaded by igneous rock at Taoyi coal mine.The results of the study show that the metamorphism of coal increased and it's ability of adsorption dropted after invaded by igneous rock,and that Pressure-constant b is negative,so it's isothermal adsorption curve does not meet to the Langmuir equation and does not conform to category 6 isotherm curves.
