在致力于达成“碳中和”与“碳达峰”宏伟目标的背景下,探索废弃矿井作为二氧化碳地质封存的有效载体,对于提升资源循环利用效率及减缓全球气候变化具有显著价值。本文系统性地探究了将废弃矿井应用于CO2封存的可行性,多维度地涵盖了地质构造特征、埋藏深度适宜性,以及地温条件等关键要素。同时,本文深入剖析了CO2对封存设施潜在的腐蚀影响机制,并对废弃矿井内实施CO2封存所涉及的安全隐患进行了详细的阐述,旨在全面评估该技术的环境适应性与风险控制能力,进一步讨论了安全监测技术在CO2封存领域的适用性和CO2封存的风险分析。对于推动废弃资源再利用、实现低碳可持续发展目标具有深远的理论与实践意义。In the context of striving to achieve the grand goals of “carbon neutrality” and “carbon peaking”, exploring abandoned mines as an effective carrier of geological storage of carbon dioxide is of significant value for improving the efficiency of resource recycling and mitigating global climate change. This paper systematically explores the feasibility of applying abandoned mines to CO2 storage, covering key factors such as geological structure characteristics, suitability of burial depth, and geothermal conditions in multiple dimensions. At the same time, this paper deeply analyzes the potential corrosion mechanism of CO2 in storage facilities and elaborates on the potential safety hazards involved in the implementation of CO2 storage in abandoned mines, aiming to comprehensively evaluate the environmental adaptability and risk control ability of the technology and further discuss the applicability of safety monitoring technology in the field of CO2 storage and the risk analysis of CO2 storage. It has far-reaching theoretical and practical significance for promoting the reuse of waste resources and achieving low-carbon sustainable development goals.
