摘　　要：煤层瓦斯损失量的计算是瓦斯量测定中的关键步骤,计算的准确度将直接影响实验结果。文章基于野外瓦斯解吸原始数据,通过国标法和泥浆法来分别计算瓦斯损失量。结果表明:国标法和泥浆法由于解吸时间的不同,导致其瓦斯损失量的差异。恰当的确定解吸时间点,对于计算瓦斯损失量尤为重要。通过计算对比,得出泥浆法确定解吸时间点的方法更准确。The calculation of gas loss in coal seam is a key step in gas measurement,and the accuracy of calculation will directly affect the experimental results.In this paper,based on the original data of gas desorption in the field,the amount of gas loss is calculated by national standard method and mud method respectively.The results show that there is a difference in the amount of gas loss between the national standard method and the mud method because of the different desorption time.It is particularly important to determine the desorption time properly for calculating the amount of gas loss.Through calculation and comparison,it is concluded that the mud method to determine the desorption time is more accurate.
