摘要
Within the framework of achieving carbon neutrality,various industries are confronted with fresh challenges.The ongoing process of downsizing coal industry operations has evolved into a new phase,with the burgeoning proliferation of abandoned mines posing a persistent issue.Addressing the challenges and opportunities presented by these abandoned mines,this paper advocates for a scientific approach centered on the advancement of pumped storage energy alongside gas-oil complementary energy.Leveraging abandoned mine tunnels to establish pumped storage power stations holds significant ecological and economic importance for repurposing these sites.This initiative not only serves as an effective means to restore the ecological balance in mining regions but also provides an environmentally friendly approach to repurposing abandoned mine tunnels,offering a blueprint for economically viable pumped storage power stations.This article delineates five crucial scientific considerations and outlines seven primary models for the utilization of abandoned mine sites,delineating a novel,comprehensive pathway for energy and power development that emphasizes multi-energy complementarity and synergistic optimization within abandoned mines.
随着中国地下能源的长期开采,废弃矿井数量将持续增加,为能源再利用和生态恢复带来新的挑战和机遇。将废弃矿井改造为抽水蓄能电站,并在矿井周边形成多能源互补开发模式,为矿区生态恢复和矿井再利用提供了一种绿色、经济的方案。本文总结了五个关键科学问题:水道系统和地下厂房的防渗、支护和加固,多巷道的引流和节流,人员与设备的安全保障,以及废弃矿井的水下传感和大数据系统。根据废弃矿井的开发场景,划分三种开发利用模式:露天矿坑全地表利用、塌陷矿井半地表利用和废弃矿井全地下利用。结合抽水蓄能电站规模和城市电网特性,提出四种电网模式,确保电能输送、调峰以及光伏电站的联合运行,充分发挥废弃矿井的资源潜力。通过全面梳理这五个关键科学问题和七种利用模式,本文为废弃矿井的多能源互补综合开发提供了明确的路径,并为中国未来废弃矿井的抽水蓄能和新能源电站开发提供了重要参考。
