摘　　要：煤炭地下气化具有经济、能开采难接近煤层和环境友好等优点,再度成为能源转化与利用技术而兴起.综述了煤炭地下气化技术发展状况及经济和环境效益,煤炭地下气化可能对地下水造成的有机和无机污染,以及污染地下水的修复技术;提出大面积煤炭地下气化时污染物是否会在地下水中聚集、地下水及围岩系统是否能够完全消除污染物等有待进一步研究的课题.Underground coal gasification （UCG）has re-emerged as an energy technology for coal conversion and utilization because of its advantages such as attractive economics, ability to access inaccessible coals and envi- ronmental friendly. The development status and economic and environmental benefits of UCG are introduced, and the organic and inorganic pollution of groundwater caused by UCG and remediation of polluted groundwater are also analyzed. Based on the analysis above it has been posed that problems, whether the pollutants will be gathered in groundwater or eliminated fully by the system composed of groundwater and surrounding rock when the coal seams are gasified in a large area.
