| 摘 要： | 用直接法测定煤层瓦斯含量时,最难控制、误差也最大的就是瓦斯损失量的计算。目前,图解法和最小二乘法是计算瓦斯损失量最为常用的方法,采用这2种方法对煤层瓦斯含量测定过程中的瓦斯损失量进行了计算,并进行了比较分析,然后在统计实测数据的基础上分析比较这2种方法对瓦斯损失量测定准确度的影响。

| Abstract: | When using the direct method to measure the gas content in coal seam,the most difficult to control and the largest error is gas loss quantity calculation.At present,using the graphic method and the least squares method to calculate the loss quantity of gas are the most commonly method.In this paper,two methods were used to calculate the gas loss quantity in measuring coal seam gas content,and the results were compared and analyzed.Then on the basis of statistical measured data,the influence of the two methods on the accuracy of gas loss quantity was analyzed and compared. |
