摘　　要：煤炭地下气化(UCG)技术通过将气化剂注入地下煤层,生成合成气供能源或化工利用,具有高效、低碳等优点。综述国内外UCG技术的发展历程、技术进展、应用现状、面临的挑战及未来发展方向。国外方面,美国、苏联及欧盟国家通过长期试验和技术探索,形成了现代UCG技术体系,但仍面临气化通道稳定性、环境污染等挑战。国内UCG技术研究起步较晚,但在国家科技计划支持下,近年来在气化通道建设、气化过程控制等方面取得显著进展,并成功建成多个示范工程。然而,UCG技术的产业化进程仍面临地质条件复杂、技术难度高及经济投入大等挑战。未来,需加大技术创新和研发投入,推动示范项目和商业化应用,加强国际合作与交流,并注重环境保护和生态安全,以实现UCG技术的可持续发展,为能源结构转型和可持续发展战略提供重要支撑。Underground coal gasification(UCG) technology injects gasification agents into underground coal seams to generate synthetic gas for energy or chemical utilization,which has the advantages of high efficiency and low carbon.Summarize the development history,technological progress,application status,challenges faced,and future development directions of UCG technology both domestically and internationally.Abroad,the United States,the Soviet Union and the EU countries have formed a modern UCG technical system through long-term experiments and technical exploration,but they still face challenges such as gasification channel stability and environmental pollution.Domestic UCG technology research started late,but with the support of the national science and technology plan,remarkable progress has been made in the construction of gasification channels and gasification process control in recent years,and a number of demonstration projects have been successfully built.However,the industrialization process of UCG technology still faces challenges such as complex geological conditions,high technical difficulty and large economic input.In the future,it is necessary to increase investment in technological innovation and research and development,promote demonstration projects and commercial applications,strengthen international cooperation and exchanges,and pay attention to environmental protection and ecological security,in order to achieve the sustainable development of UCG technology,and provide important support for the energy structure transformation and sustainable development strategy.
