煤层气开发利用的经济效益分析

瓦斯事故是中国煤矿安全事故居高不下的主要原因，是重大的安全隐患．中国煤矿瓦斯事故防治应转变观念，树立瓦斯既是有害气体，但又是一种优质能源，应将它作为清洁能源进行开发利用的观念．为此，介绍了中国的煤层气资源及利用概况，分析了煤层气资源的利用前景，并用净现值法和内部报酬率法对某典型煤矿煤层气利用工程的经济效益进行分析评价．结果表明，煤层气的开发利用不仅可以减少瓦斯事故，节约能源，减少环境污染，还具有显著的经济效益．

Economic Benefit Analysis on the Exploitation and Utilization Coal bed Methane

The gas accident in Coal Mine is an important safe hidden trouble.The notion on the prevention and cure of gas accident should be changed.Coal gas is a kind of deleterious gas,but it is a clean energy resource.The actualities of coal bed methane resources and its use in our country are reviewed.The foreground for the use of coal bed methane is analyszed.The economic benefit of coal bed methane utilization is evaluated by the Net Present Value(NPV) and the Internal Rate of Return(IRR)method.The results are shown that the utilization of the coal bed methane can decrease the gas accident,save energy source,reduce the environmental pollution,and have remarkable economic benefit.
