介绍了地勘解吸法在我国煤田地质勘探和煤层瓦斯地面开发时的应用,该法是最常用的煤层瓦斯含量测定方法.但实践证明,仍存在着许多明显的技术缺陷,如测值偏低,误差随取样深度增大而增加等.对此详细剖析了存在这些问题的根本原因.

英文摘要：

The paper introduced the application of the geology survey sorption method to the coal field geological survey and coal bed methane surface development in China. The method is the most common method for seam gas content measurement. But the practices showed that there were many obvious technical problems, such as the measured value too lower, the error increased with the depth of sampiing and others. Therefore the paper had a detailed analysis on the fundamental causes of the existing problems.
