深部煤层资源开采由于技术要求高、运营成本高，在传统的统一补贴政策下普遍不经济，导致煤层气抽采不充分，存在安全隐患或排放隐患。针对这些问题，提出了政府-企业均衡差异化补贴机制，以促进多煤层气开采。具体而言，差异化补贴机制保证了深度资源比浅层资源获得更多的单位补贴。建立了一个双层多目标优化模型，解决了政府与煤层气企业之间的互动关系，寻求能源开采量增加与财政支出之间的综合平衡。实例应用表明，实施差别化补贴能有效促进多煤层气开采。进一步的讨论表明，较低的能源产出目标和适度的补贴可以促进深部煤层开采。本文提出的差别化补贴机制适用于深部煤层资源丰富地区的煤层气产业。我们确定的适当补贴政策可作为政府推动多煤层能源开采的参考。
Because of strict technical requirements and high operational costs, exploiting deep coal seam resources is generally uneconomic under traditional uniform subsidy policies, which has resulted in an inadequate extraction of coalbed methane (CBM) and many safety risks or potential emission problems. To deal with these problems, an authority-enterprise equilibrium differentiated subsidy mechanism is proposed to promote CBM extraction in multiple coal seams. Specifically, the differentiated subsidy mechanism ensures that deep resources get more unit subsidies than shallow resources. A bi-level multi-objective optimization model is developed to resolve the interactive relationships between the authority and CBM enterprises, which also seeks a comprehensive balance between increased energy extraction and fiscal expenditure. A case application indicates that implementing differentiated subsidies could effectively promote multiple coal seam CBM extraction. The further discussion showed that a low energy output target and a moderate subsidy can accelerate deep coal seam extraction. Our proposed differentiated subsidy mechanism can be applied to the CBM industry in regions that own abundant deep coal seam resources. Our confirmed appropriate subsidy policy can be used as a reference for the government to promote energy extraction in multiple coal seams.
