【目的】在煤炭资源持续高强度开发与能源供给侧结构性改革的背景下，安徽省关闭了一批资源枯竭、产能落后的煤矿，而关闭煤矿仍赋存有地下空间、遗煤、瓦斯、矿井水、土地与基础设施设备等资源，开展关闭煤矿资源再利用具有现实的工程价值和经济效益。【方法】统计自2013年以来安徽省59座关闭煤矿基础信息和再利用现状，分析关闭煤矿分布特征、遗留资源与再利用潜力；构建安徽省关闭煤矿数据库与WebGIS云平台，实现关闭煤矿信息查询分析与可视化；以潘一矿与石台煤矿为例，分别介绍遗留瓦斯抽采与半地下抽水蓄能的关闭煤矿再利用方案。【结果和结论】结果表明：安徽省关闭煤矿主要集中分布在两淮矿区，部分关闭煤矿关闭时间较短、遗留资源丰富、产权隶属清晰，再利用潜力较大；潘一关闭煤矿综合使用封闭墙压管抽采、原抽采钻孔抽采和地面钻井抽采的立体化遗留瓦斯抽采技术，实施关闭煤矿采空区“排水−抽采−利用”的一体化工程，3年内累计抽采瓦斯量4 840万m³、发电8 590万kW·h、直接经济效益5 120万元，同时保障了相邻矿井的安全生产；石台关闭煤矿拟建设半地下抽水蓄能电站，地下空间可提供有效库容30万m³、装机容量35 MW。案例分析表明安徽省部分关闭煤矿资源再利用在技术经济上具有合理性，但仍需开展进一步深入研究。

[Objevtive] With the continuously intensive exploitation of coal resources and the structural reform of energy supply, many coal mines in Anhui Province have been closed due to resource depletion or backward production capacity. However, the closed coal mines still host resources such as underground spaces, residual coals, gas, mine water, land, and infrastructure equipment. Hence, reutilizing resources in closed coal mines holds significant engineering value and economic benefits. [Methods] Based on the general information and reutilization status of 59 coal mines in Anhui Province that have been closed since 2013, this study analyzed the distribution characteristics, residual resources, and reutilization potential of these coal mines. A database and a WebGIS cloud platform were developed for these closed coal mines, allowing for their information search, analysis, and visualization. This study explored the Pan-1 and Shitai coal mines as examples, presenting schemes for reutilizing the closed coal mines through residual gas drainage and semi-underground pumped storage. [Results and Conclusions] Key findings are as follows: (1) The closed coal mines in Anhui Province are primarily distributed in the Huainan and Huaibei areas. Some of them feature relatively short closure durations, abundant residual resources, and clear property rights, demonstrating the considerable potential for resource reutilization. (2) For the closed Pan-1 Coal Mine, the implementation of the 3D residual gas drainage technique that combines sealed-wall pressurized drainage, drainage using original boreholes, and drainage through surface drilling enables integrated engineering involving drainage, gas drainage, and resource utilization within the goaf of the closed coal mine while ensuring the safe production of adjacent mines. Consequently, the Pan-1 Coal Mine yielded cumulative gas drainage of 4840 × 10⁴ m³ and power generation of 8590 × 10⁴ kW·h within three years, corresponding to direct economic benefits of 5120 × 10⁴ CNY. (3) For the closed Shitai Coal Mine, its underground space can provide an effective storage capacity of 30 × 10⁴ m³, making it possible to transform into a semi-underground pumped storage power plant with an installed capacity of 35 MW. The case analyses indicate that some of the closed coal mines in Anhui Province manifest technical and economic feasibility in resource reutilization, and further research is required.
