摘　　要：分别以富氧和富氧-水蒸气为气化介质,进行了大雁褐煤的地下气化模型实验.研究了鼓风量和汽氧比对煤气组成、气化稳定性以及煤层气化速率的影响,并进行了富氧-水蒸气地下气化过程的物料衡算.实验结果表明,通过采取合适的气化参数,大雁褐煤的地下气化过程可以稳定进行.With oxygen and oxygen-steam as gasification medium, the model test of underground gasification of Dayan lignite were conducted. The studies were focused on the influence of oxygen blast and steam/oxygen ratio on the gas composition, gasification stability and rate. In the same time, the mass balance of oxygen-steam gasification process was conducted. The results show that the underground gasification of Dayan lignite has high stability form to use suitable parameters.
