为准确掌握矿井煤层瓦斯含量分布,有效治理瓦斯灾害及开发利用瓦斯资源,对比分析了寺河煤矿、赵庄煤矿井田及邻近区域实施的92口煤层气井瓦斯含量,地勘时期测定的86组瓦斯含量和生产期间井下实测的原始瓦斯含量。结果表明:寺河煤矿煤层埋深在300~450 m时,煤层气含量约为井下实测瓦斯含量的1.28~1.37倍,地勘瓦斯含量约为井下瓦斯含量的1.01~1.10倍。赵庄煤矿煤层埋深在600~750 m时,煤层气含量约为井下实测瓦斯含量的1.05~1.41倍;煤层埋深在450~700 m时,地勘瓦斯含量约为井下实测瓦斯含量的1.01~1.35倍。基于此,得到多源瓦斯含量数据产生差异的主要原因为参数测试条件不同,采样方式不同、残存瓦斯含量测定方法及内容不同等。

In order to accurately understand the gas content distribution of the seams in the mine,to effectively control gas disaster and to develop and utilize the gas r esources,the paper analyzed the gas contents of 92 coalbed methane wells drilled in Sihe Mine ,Zhaozhuang Minefield and the neighboring regions. During the geological e xploration period, there were 86 gas contents measured there were in-situ gas contents measured in the underground mine during the mine production period. The results s howed that when the seam depth in Sihe Mine was about 300 ~ 450 m,the coalbed methane content was about 1.28 ~ 1.37 times higher than the site measured gas conten t in the underground mine and the gas content during the geological exploration period was about 1. 01 ~ 1. 10 times higher than the gas content measured in the undergro und mine.When the seam depth in Zhaozhuang Mine was about 600 ~ 750 m,the coalbed methane content was about 1.05 ~ 1.41 times higher than the site gas content me asured in the underground mine.When the seam depth was about 450 ~ 700 m,the geological gas content was about 1.01 ~ 1.35 times higher than the site measured gas C ontent in the underground mine.Based on the circumstances,the main causes to make differences of the multi-source gas content data would be the different parameter me asuring and testing condition,ifferent sampling method,residual gas content measuring method and different contents.
