【摘要】：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。
[Abstract]:In order to accurately understand the distribution of gas content in coal seam, effectively control gas disaster and develop and utilize gas resources, the gas content of 92 coalbed methane wells implemented in Sihe Coal Mine, Zhaozhuang Coal Mine and its adjacent areas is compared and analyzed. 86 groups of gas content measured during geological prospecting period and raw gas content measured during production period. The results show that when the depth of coal seam in Sihe coal mine is 300 ~ 450 m, the coal bed methane content is 1.28 ~ 1.37 times that of underground gas content, and the gas content of geological prospecting is 1.01 ~ 1.10 times of underground gas content. When the coal bed depth of Zhaozhuang coal mine is 600 ~ 750m, the coal bed methane content is about 1.05 times as much as the underground gas content, and when the coal seam buried depth is 450 ~ 700m, the geological exploration gas content is 1.35 times of the underground gas content. Based on this, the main reasons for the difference of multi-source gas content data are different parameter test conditions, different sampling methods and different methods and contents of residual gas content.
