摘  要:煤炭地下气化技术被称为第二代采煤法,是煤炭开采利用技术的重要补充。基于对国内外近几年大量文献资料的调研分析,从地质条件评价、三维地震技术、钻探技术等3个方面,综述了煤炭地下气化地质选址评价及开采技术发展现状,指出地质条件综合评价体系、水文地质精细勘查与评价、三维地震勘查、多分支定向井技术是未来煤炭地下气化技术的发展新趋势。The coal underground gasification has been called as second-generation coal mining that is the important complement to coal exploitation and utilization. Based on investigation and analysis of a large number bibliographical information data both home and abroad in recent years, summed up underground gasification geological siting assessment and exploitation technology development status quo from three aspects of geological condition assessment, 3D seismic prospecting and drilling technologies. The study has pointed out that the geological condition comprehensive assessment system, hydrogeological fine exploration and assessment, 3D seismic prospecting and multi-branched directional well technologies are the new development trend of coal underground gasification technology.
