Abstract

The measurement error in direct determination of the gas content within a coal bed is considered. The best known methods of direct determination are based on sorption theory and fail to take into account that most methane within the bed is in solid solution. Accordingly, a different method is required. The model of the bed’s gas content outlined in the present work incorporates current notions regarding the aggregate state of methane and its bonds with the coal. The influence of dissolved methane on the error in direct determination of the gas content within a coal bed is studied experimentally.

溶解甲烷对煤层含气量直接测定误差的影响

摘要

考虑了直接测定煤层内瓦斯含量的测量误差。最知名的直接测定方法是基于吸附理论，没有考虑到床内的大部分甲烷都处于固溶体中。因此，需要不同的方法。目前工作中概述的床层气体含量模型结合了当前关于甲烷聚集状态及其与煤结合的概念。实验研究了溶解甲烷对煤层内含气量直接测定误差的影响。
