煤炭地下气化技术

Underground Coal Gasification Technology

介绍了煤炭地下气化的基本原理、应用地质条件、国内外发展概况以及与传统的井工开采煤炭相比的优越性。分析了实施煤炭地下气化所需解决的地下气化炉结构和气化工艺参数的选择、高温条件下煤和岩石物理化学性质的测试、物探测试和监控、大口径定向钻进等关键技术问题 ,提出了我国发展煤炭地下气化技术的对策。

Fundamental principle, applicable geological condition, domestic and oversea development of underground gasification and its advantage compared with traditional underground coal mining are introduced. The key problems of structure of gasifier carrying out underground gasification, selection of gasification process and parameters, test on physical and chemical properties of coal and rock under high temperature, geophysical propecting measuring and monitoring and controlling, large diameter directional drilling and so on are analyzed. Countermeasures on developing underground gasification in China are presented.
