从地质角度谈煤的地下气化

Discussion on Underground Gasification of Coal from the View Point of Geology

本文从地质角度出发,对煤的地下气化方法的优点、应用的局限性、当前的技术难点及在我国能源供应紧张形势下的适用性进行了探讨。认为虽然煤层地下气化技术还不很成熟,但仍不失为一种可能回收煤矿区已废弃于地下的煤炭资源的有效手段。特别在我国能源供应最紧张的沿海经济较发达省区,此项技术有可能获得较好的经济效益。

Merits and limitations in application of the technique of underground gasification of coal to present China are discused from the view point of geology .It is emphasized that it still is an effective means for recovering the abandoned reservees at the underground coal mines,even though the technique is not yet perfect .Particularly ,in those areas with pros-perous economics but suffering from energy supply, the technique may have more oppor-tunity to gain more economic effects.
