摘要: 中国自开展“光伏+采煤沉陷区”模式建设的探索工作以来,多地以绿色能源创新应用带动采煤沉陷区经济转型,研究内容聚焦在“光伏+采煤沉陷区”模式的具体项目设计实践、地基稳定性评估、综合效益评估等方面,并取得了一些研究进展,但目前存在一些客观问题限制了该模式的推广应用。基于文献研究法,对中国“光伏+采煤沉陷区”模式发展的特征与规律进行了分析,总结其发展历程,对其推进过程中存在的客观问题进行了探索并提出了相应的解决措施。研究结果表明:1)中国“光伏+采煤沉陷区”模式的应用主要分布在具有高强度煤炭开采基础的地区。2)该模式下,光伏支架的选型与设计需要考虑沉陷稳定性、地层情况、洪水位及开发模式等多方面影响因素,并需要对项目进行包含经济效益、生态效益、社会效益在内的综合效益评估。3)该模式存在采煤沉陷区的土地性质发生变化未及时办理转用审批、电网建设滞后影响消纳通道、固定式水上光伏电站应用的便捷性与环保性有待提高等问题。4)在项目推进过程中,要确保光伏电站所用采煤沉陷区的土地权属合法合规;创新就地消纳模式;建议利用遥感和大数据手段监测水域情况,并通过高效智能运维管理对采煤沉陷区中水上光伏电站的稳定运行作出有效保障。5)建议在项目建设前期的采煤沉陷区治理中要优化政府财政支出,建立采煤沉陷区治理资金使用效率评估机制;不断拓宽资金渠道,完善管理及监督机制,从而提升财政补贴和项目投资在采煤沉陷区生态修复中的作用。Abstract: Since the exploration of the construction of "PV + coal mining subsidence area" in China,many places have used green energy innovative applications to drive the economic transformation of coal mining subsidence areas. The research content is mostly focused on the specific project design practices,foundation stability assessment,and comprehensive benefits evaluation of the "PV + coal mining subsidence area" mode. Some research progress has been made,but there are currently some objective problems restricting the promotion and application of this mode. Based on the literature research method,this paper analyzes the characteristics and laws of the development of " PV + coal mining subsidence area" mode in China,summarizes its development process,explores the objective problems existing in its promotion process and puts forward corresponding solutions. The research results show that:1) The application of "PV + coal mining subsidence area" mode in China is mainly distributed in areas with high-intensity coal mining foundation. 2) In this mode,the selection and design of PV brackets need to consider many influencing factors such as subsidence stability,stratum conditions,flood level and development mode,and it is necessary to conduct a comprehensive benefit evaluation of the project,including economic benefits,ecological benefits,and social benefits. 3) There are some problems in this mode,such as the nature of the land in the coal mining subsidence area has changed,but the approval for conversion has not been handled in time,the lagging construction of the power grid affects the consumption channel,the convenience and environmental friendliness of the application of fixed PV power station on water need to be improved. 4) During the project promotion process,it is necessary to ensure that the land ownership of the coal mining subsidence area used by the PV power station is legal and compliant.Innovative on-site consumption mode. It is recommended to use remote sensing and big data methods to monitor the water conditions,and to provide effective guarantees for the stable operation of PV power station on water in coal mining subsidence areas through efficient and intelligent operation and maintenance management.5) It is recommended to optimize government financial expenditures and establish an evaluation mechanism for the efficiency of governance fund utilization of coal mining subsidence areas during the early stages of project construction. Constantly broaden the funding channels and improve the management and supervision mechanism,so as to enhance the role of financial subsidies and project investment in ecological restoration of coal mining subsidence areas.
