摘　　要：被保护煤层的残余瓦斯含量是瓦斯治理的一项重要基本参数,也是考察其保护效果的一项基本指标。基于被保护煤层卸压瓦斯的运移规律,利用煤质工业分析值及瓦斯吸附实验,并结合Langmuir公式对残余瓦斯含量计算,得出被保护煤层残余瓦斯含量的计算方法。Remained gas content is an important basic parameter of gas control in protected coal seam,which is also a basic index to assess its protective effects.The calculation of remained gas content is based on moving law of pressure-relief gas in protected coal seam,it makes use of coal quality industry analysis value and gas adsorption experiment,combined with Langmuir formula.Finally,the calculation method of remained gas content can be obtained.

关 键 词：被保护煤层 下保护层 瓦斯运移规律 残余瓦斯含量
