| 摘 要： | 保德煤矿位于鄂尔多斯盆地东缘，煤层气资源较为丰富。在矿区深部区域存在高瓦斯风险，目前煤矿井下治理瓦斯方法不能很好适应生产需要，对安全生产造成一定影响。为了解决高瓦斯风险，需要进一步探索新的高效快速治理办法，地面治理瓦斯是其中一种方法。为了验证该方法的有效性，对该区进行了瓦斯地质勘查和地质分析研究；通过获取的现场和试验数据，结合煤矿已有资料，对矿区主力煤层8号和11号煤的储层特征展开研究，分析控制瓦斯富集的主要因素，认为该区煤层分布稳定，构造简单，封盖条件较好，瓦斯含量高于煤矿安全指标，煤层渗透率较高，属于低压储层，在深部形成瓦斯富集区，具备开展地面瓦斯治理的条件。

| Abstract: | Baode Coal Mine is located in the eastern edge of Ordos Basin，where are abundant in coalbed methane resources.In the deep area of the mine there is a high gas risk and at present coal mine gas treatment method can not be well adapted to the production needs.In order to solve the high gas risk it need to further explore new and efficient rapid management approach，CBM Ground Extraction is one of the methods.In order to verify the effectiveness of the method，gas geological exploration is done in the area.Based on the data obtained from the site and the experimental data and combined with coal mine information，the reservoir characteristics of No.8 and No.11 coal in the main coal seam of the mining area are studied，and the main factors controlling the gas enrichment are analyzed.The distribution of coal seam is stable，the structure is simple，sealing conditions are better，the gas content is higher than the coal mine safety index，the coal seam permeability is higher，pressure reservoir is low.In the deep formation gas accumulation area，CBM ground extraction can be carried out. |
