中文摘要：

文章通过利用大气介质中煤的瓦斯解吸过程模拟试验装置采集不同变质程度煤样,在不同粒度、瓦斯压力条件下,模拟煤样在大气介质中煤的瓦斯解吸过程,找出影响大气介质中煤的瓦斯解吸过程的主控因素,得到表述模拟大气介质等压条件下瓦斯解吸过程较为理想的经验式。这不仅有利于提高煤层瓦斯含量测定方法的稳定性与准确性,更有利于提高我国煤矿瓦斯防治技术水平和煤矿资源评价水平。

英文摘要：

In this paper, by using simulation test device for air medium coal gas desorption process of different metamorphic de-gree of coal sample collection, under the condition of different particle size, gas pressure, simulation of coal sample in air medium coalgas desorption process, affecting air medium coal gas desorption process, the main factors are described to simulate air medium underthe condition of constant pressure gas desorption process of ideal theory empirical formula. It is not only beneficial to improve the stabil-ity and the accuracy of coal bed gas content measurement method, but is more advantageous to improve the level of coal mine gas pre-vention and control technology in our country and coal resource evaluation level.
