露天开采作为煤层气最重要的开采方式之一，却很少从政策激励和管理优化的角度进行探索，严重制约了煤层气产业的规模化发展。针对这一问题，建立了基于多利益相关者均衡的煤层气开采与利用补贴分配机制。考虑到地表开采过程中甲烷浓度较高和技术较为成熟，建议的机制涉及竞争性补贴分配机制和更大的投资，以应对巨大的运营成本压力。与传统的统一单位补贴政策相比，该分配机制允许企业在增加产量的情况下获得额外的更高补贴。为了提高补贴分配机制的适用性，采用双层规划方法将多个利益相关者之间复杂的相互作用整合到所提出的策略中，并利用多目标理论实现能源利用与支出控制之间的权衡。应用结果表明，补贴分配策略可以促进煤层气露天开采利用，并进一步分析表明，设置高满意度和低能耗目标可以提高能源利用率。本文的研究为促进煤层气规模利用提供了重要参考。
As one of the most important methods for extracting CBM, surface mining was rarely explored from a policy incentive or management optimization perspective, which has significantly limited the scale development of the CBM industry. To deal with this problem, a multi-stakeholder equilibrium-based subsidy allocation mechanism was developed to promote CBM extraction and utilization. Considering the higher methane concentrations and more mature technology in the surface mining process, the proposed mechanism involves a competitive subsidy allocation mechanism and larger investment to deal with the significant operational cost pressures. Compared with the traditional uniform unit subsidy policy, the allocation mechanism allows enterprises to access an extra higher subsidy if they increase output. To enhance the applicability of the subsidy allocation mechanism, the complex interactions between the multiple stakeholders were integrated into the proposed strategy using a bi-level programming method, and a trade-off between energy utilization and expenditure control was achieved using multiple objective theory. The application results showed that the subsidy allocation strategy could promote CBM surface mining utilization, and further analyses indicated that setting a high satisfaction degree and low energy targets could enhance energy utilization. The research in this paper provides an important reference for the promotion of CBM scale utilization.
