| 摘 要： | 煤层气是一种新能源和优质化工原料,地面开发可以节能减排,降低瓦斯灾害,具有极强的正外部性。但煤层气与煤炭共生在一起,开发一种会影响另一种。通过分析煤层气地面开发现状,探讨了它在地质勘探、矿井地质、矿井通风、综合开采、煤炭气化和环境保护等方面存在的负外部性。外部性影响和制约着煤层气产业的健康发展。正外部性可以通过国家补贴、税收和费用减免等措施来强化;负外部性则可以通过淘汰落后或不合理的产能技术,创新开发工艺,以及提高采收率等来减少,并通过明晰产权和联合开发,使部分负外部性转化为内部性,达到共赢之效果。

| Abstract: | Coalbed methane(CBM) is a type of clean energy and good chemical raw material,CBM exploitation and utilization can save energy,reduce emission and mine gas disaster,therefore,it is of a strong externality.But coal and CBM are co-existing in coal seam,exploitation of anyone will definitely affect the other.Through analysis of CBM development from surface,this paper discusses the negative externalities in geological exploration,coal mining geology,mine ventilation,integrated mining,gasification of coal and environment protection.The external-ity affects and involves the healthy development of the CBM industry.The positive externality can be strengthened by preferential subsidy,tax policy,rate relief and so on.The negative externality can be reduced by ousting some outdated production style,innovating production method,improving recovery rate.At the same time,part of nega-tive externality can be transformed into the interior and win-win situation can be achieved through clarification of property rights and joint development. |
