在实验室研究了钻屑瓦斯解吸指标与瓦斯压力之间的对应关系，两者之间符合乘幂关系。在此基础上利用煤层瓦斯含量与瓦斯压力的对应关系，建立了煤层瓦斯含量与钻屑瓦斯解吸指标之间的对应关系；在现场利用直接法对煤层瓦斯含量进行了测定，并同时测定了钻屑瓦斯解吸指标，通过煤层瓦斯含量与钻屑瓦斯解吸指标之间的对应关系算出了间接法计算出来的煤层瓦斯含量值，采用绝对误差以及相对误差对二者进行了对比。结果表明，采用钻屑解吸法计算煤层瓦斯含量是可靠的。
在實驗室研究瞭鑽屑瓦斯解吸指標與瓦斯壓力之間的對應關繫，兩者之間符閤乘冪關繫。在此基礎上利用煤層瓦斯含量與瓦斯壓力的對應關繫，建立瞭煤層瓦斯含量與鑽屑瓦斯解吸指標之間的對應關繫；在現場利用直接法對煤層瓦斯含量進行瞭測定，併同時測定瞭鑽屑瓦斯解吸指標，通過煤層瓦斯含量與鑽屑瓦斯解吸指標之間的對應關繫算齣瞭間接法計算齣來的煤層瓦斯含量值，採用絕對誤差以及相對誤差對二者進行瞭對比。結果錶明，採用鑽屑解吸法計算煤層瓦斯含量是可靠的。

The corresponding relationship between drilling cutting methane desorption index and coal seam gas content is researched in the laboratory, they accord with exponent relation, using the corresponding relationship between coal seam gas content and gas pressure, the corresponding relationship of coal seam gas content and drilling cutting methane desorption index is established; coal seam gas content is determined on the scene by using the direct method,at the same time, drilling cutting methane desorption index is determined, by the corresponding relationship between coal seam gas content and drilling cutting methane desorption index, the value of coal seam gas content is calculated by using indirect method. They are compared with absolute error and relative error. The results show that using the drilling cutting desorption method to calculate coal seam gas content is reliable.
