摘  要:基于我国煤矿区煤层气地面开发项目的特点,响应国家关于“加快煤层气勘探开发一体化”和矿井“先抽后建”的号召,在玉溪煤矿一采区11个工作面完成地面煤层气抽采井的工作部署,设计了两种不同的煤层气开发方案,并采用项目经济评价的方法,从财务的角度分析两种方案的盈利能力。评价结果表明:方案一和方案二税后财务内部收益率分别为8.91%和13.01%;税后财务净现值分别为4069.78万元和18116.97万元;税后投资回收期分别为6.40年和5.69年,方案一和方案二在经济上均具有一定的盈利能力,且方案二的盈利能力要强于方案一,从财务盈利能力上可以看出,方案二优于方案一。Based on the characteristics of coalbed methane development projects in China’s coal mining areas and responding to the national call to speed up the integration of coalbed methane exploration and development and drainage before mine construction,the deployment of coalbed methane extraction wells at 11 working faces in No.1 District of Yuxi Coal Mine is completed.Two different schemes of coalbed methane development are designed,and the profitability of these two schemes is analyzed from the financial point of view by the method of project economic evaluation.The evaluation results the indicate that:the after-tax financial internal rate of return of schemeⅠand schemeⅡis 8.91%and 13.01%respectively;the after-tax financial net present value is RMB40.6978 million and RMB 181.1697 million respectively;the after-tax investment payback period is 6.40 years and 5.69 years respectively.Both SchemeⅠand schemeⅡhave certain economic profitability,and the profitability of schemeⅡis better than that of schemeⅠ.It can be seen from the financial profitability that schemeⅡis better than schemeⅠ.
