| 摘 要： | 瓦斯损失量推算的准确与否直接影响到瓦斯含量的测定结果。通过对瓦斯损失量推算数学模型、取样方法、煤体解吸性能等方面的分析,确定了煤层瓦斯解吸是多因素动态耦合作用的结果,应根据实际情况对数学模型进行选取。为减小损失瓦斯量的影响误差,应尽量缩短煤体暴露时间及保持煤芯的完整性与密封性。

| Abstract: | Whether the calculation of gas loss amount is accurate or not,it directly affects the results of determination of gas content.Through analyzing the mathematical model that calculated from gas loss quantity,sampling method,coal desorption performance and other aspects,the paper determines that the coalbed gas desorption is the result of multiple factors dynamic coupling effect,and it should be selected based on the actual situation of the mathematical model.To reduce the influence error of gas loss amount,the exposure time of coal body should be as short as possible and maintain the integrity and tightness of the coal core. |
