| 摘 要： | 恩洪矿区是云南省重要产煤基地，晚古生界的上二叠统宣威组是主要含煤岩系，其煤层镜质组含量较高，变质程度中等，蕴藏着丰富的煤层气资源。综合研究表明：该区煤层气富集的控制因素主要为煤层厚度、煤岩组分、煤级、吸附性能和良好的保存条件。

| Abstract: | The Enhong coal mining district is the main coal production basement, where the Permian Xuanwei Formation is the main coal-bearing sequence, and preserves abundant coalbed methane resource. In the formation the coals are characterized by higher vitrinite content and medium metamorphic grade. The comprehensive research showed that coalbed methane accumulation is mainly controlled by coal seam thickness, coal petrological composition, coal rank, adsorbability and good preservation conditions. |
