Abstract: This paper studies the coal bed characters, gasbearing, absorption and coalbed methane resource,and uses numerical simulation, COMET2 software to predict the gas production of minable coal beds,and concludes that Fumei No2 coal mine possesses a favorable coalbed methane reservoir formation and geology for development, the wells are of better gas production, indicating a prospect in development. This paper attempts to provide technical reference for the ground coalbed methane development and handling the coal mine gas in Fumei No.2 coal mine, and also shows a combination of geological analysis and numerical simulation is a vital tool in evaluating and developing coalbed methane.

Key words: coalbed methane, geological analysis, numerical simulation, development potential, Fumei No.2 coal mine

摘要： 分析研究了云南富源富煤二矿的煤层特征、含气特征、吸附特征、煤层气资源特征，并采用数值模拟手段、COMET2模拟软件，对主要可采煤层的产气情况进行了预测。综合分析认为，富煤二矿具有较好的煤层气成藏条件和开发地质条件，煤层气井具有较好的产气效果，开发前景较好。研究成果可为今后富煤二矿的地面煤层气开发，以及煤矿瓦斯治理提供一定的技术支撑和参考价值，同时也表明地质分析与数值模拟相结合是煤层气开发潜力评价的重要手段。
