摘要
煤炭地下气化是将地下的煤炭进行有控制的燃烧 ,为了使煤的燃烧和气化得到有效的控制 ,了解燃烧的火焰工作面的移动速度以及燃空区的范围是致关重要的。唐山刘庄煤矿地下气化区的试验中 ,分析了放射性测氡法在进行煤炭地下气化监测中确定燃烧火焰工作面的移动速度及以燃空区范围的可行性和有效性 ,从而提出一些建议。
Underground gasification of coal means the controlled combustion of underground coal.In order to control the combustion and gasification of coal in an effective way,it is quite important to understand the moving velocity of the burning flame working plane and the limits of burned out area.During the test conducted in the underground gasified area of the Liuzhuang coal mine,the authors analysed the feasibility and effctiveness of the radioactive radon technique in the determination of the moving velocity of the buring flame working plane and the limits of the burned out area in the process of coal underground gasification monitoring.On such a basis,some suggestions are put forward in this paper.
