【摘要】 煤炭地下气化（Underground Coal Gasification,UCG）是一种重要的煤炭资源转化技术，可提高煤炭资源的利用效率，但同时也带来地下水环境的污染风险。本文主要从UCG产生污染物对环境的影响及其修复防治角度着手，总结了UCG产生污染物的种类、转化迁移规律、净化修复方法和环境评估监测研究现状与进展，展望了未来UCG全面积极推广应加大其现场试验以及污染物监测研究力度的发展趋势，并为煤炭清洁利用领域的发展提供参考。更多还原

【Abstract】 Underground coal gasification(UCG) is a significant technology for converting coal resources and enhancing their usage efficiency.However, UCG also poses a potential risk of groundwater pollution. This paper primarily focuses on the environmental impact of pollutants generated by UCG and the measures taken to remediate and prevent such impacts. This article offers a comprehensive overview of the current state of research on the various types of pollutants produced during the UCG process, their transformation and migration patterns, purification and remediation techniques,as well as environmental assessment and monitoring methods, which explores the future development trend that UCG should be comprehensively and actively promoted to increase its field testing and pollutant monitoring research efforts, while also providing reference for the development of the field of clean coal utilization.更多还原
