摘要(Abstract)：

借助Web of Science期刊全文数据库，系统地检索了近五年关于煤炭地下气化的外文文献，共计150余篇。基于这150余篇论文的研究内容及分布特征，归纳了近期国外关于煤炭地下气化的发展现状及研究内容，探讨了煤炭地下气化的不足及理论研究内容。研究结果表明：(1)国外煤炭地下气化论文数量近五年呈现下降趋势，说明煤炭地下气化技术大规模商业化发展仍需要一定时间。其中印度和波兰两个国家的论文数量远超过其他国家，说明这两个国家对煤炭地下气化技术比较关注。(2)近五年国外研究主要倾向于建立气化模型、样品实验研究、气化污染处理、气化工艺改进及地质风险评价等方面。关于实地开展气化项目研究内容较少。(3)煤炭地下气化技术是一种包含物理和化学变化的复杂工艺，现阶段均为单一模块研究，之后随着技术创新并将地面、地下及控制等方面结合，会将煤炭地下气化向商业化发展推进。煤炭地下气化制氢及深部煤层煤炭地下气化是未来的重要发展方向。
