我省各统配局矿自1984年以来,在搜集、整理、分析历年瓦斯资料的基础上,分析研究瓦斯地质相关因素,首次编制出矿区瓦斯地质图7份,矿井瓦斯地质图35份。在此基础上,我们又编制了河北省瓦斯地质图。通过编图,对我省瓦斯地质规律有一些粗浅认识,现介绍如下供同志们参考。 一、地质特征简述 1.煤系地层及煤层 河北省煤系地层主要的成煤时期为晚古生代石炭二叠纪,中生代早、晚侏罗
Since 1984, we have collected, sorted out and analyzed the historical gas data and analyzed and studied the related factors of gas and geology. For the first time, we compiled 7 gas geological maps and 35 gas geological maps of the mine. On this basis, we also compiled the gas geological map of Hebei Province. Through the compilation of maps, we have some superficial understanding of the geology of gas in our province. Here is a brief introduction for the gay people. I. Geological Characteristics Brief Description 1. Coal measures strata and coal seams The main coal-forming period of the coal measures strata in Hebei Province are Late Paleozoic Carboniferous Permian, Mesozoic Early and Late Jurassic
