晋城矿区煤层瓦斯地质特征

Coal Bed Gas Geological Features in Jincheng Mining Area

晋城矿区位于山西省沁水煤田东南部,是我国重要的无烟煤基地之一。但由于该区煤层瓦斯含量高、浓度大,成为煤矿安全生产的主要影响因素。本文收集、整理该区大量瓦斯地质资料,分析研究了该区煤层瓦斯的赋存特征和分布规律,阐述了影响煤层瓦斯形成和赋存的主要因素。

The Jincheng mining area is located in southeasterm part of Qinshui coalfield,Shanxi,one of major anthracite base in the country.But sinqe the high coal bed gas content and concentration largely affected coalmine safety production.The auther collected and arranged a quantity of gas data,studied coat bed gas hopting and distributing patterns found out major factors affecting the forming and hosting of coal bed gas.
