摘　　要：简概述了煤炭地下气化技术,分析了该技术目前存在的问题:①技术的限制。气源稳定性差,监控手段缺失、科研人员缺失、缺少多学科的融合应用、试验缺乏,理论研究难以展开;②在经济上仍然没有竞争力。成本较高、产品开发困难;③环境问题难以解决。地下水污染、地面塌陷、CO2排量增加。提出了要成功将其商业化还需要多学科融合解决其关键技术的建议。The technology of underground coal gasification is briefly described.The existing problems of technologies are analyzed.First,the technology is limited;the stability of the gas source is poor;the monitoring methods are lacking;the scientific research personnel are lacking;the multidisciplinary integration application is lacking;the experiment is lacking and theoretical research is difficult to carry out.Secondly,the economy is still not competitive;the cost is high and the product development is difficult.Thirdly,environmental problems are difficult to solve.Groundwater pollution,ground collapse,and CO 2 emissions increases.Successful commercialization also requires the integration of multi-disciplinary solutions to solve key technologies.
