摘要：

The gas enrichment conditions in the Fuxin basin are compared to those of the Powder River basin. The coal bed depth, the gas content, the individual coal bed layer thickness, and the overall structure thickness of the Powder River basin in the U.S. were examined. The main factors affecting gas enrichment were examined. These factors include the coal-forming environment, the gas sources, the geological structure, the presence of magmatic activity, and the local hydrology. The coal-bed gas enrichment area in the Wangying-Liujia block of the Fuxin basin is then discussed by analogy. A hydrodynamic-force/dike-plugging model based on a magma fractured bed is proposed to explain the gas enrichment in this part of the Fuxin basin. High gas production is predicted in areas having similar conditions. This work will aid future coal-bed gas exploration and development.
