摘　　要：以华泰矿实际情况为依据,在U型上行通风条件下,利用Fluent流体数值仿真软件,模拟了正常采掘过程中采煤工作面发生的瓦斯喷出过程,并研究了瓦斯喷出对巷道内风流以及瓦斯浓度分布的影响。可为矿井了解瓦斯喷出的影响、制定瓦斯喷出应急处理措施等提供理论依据。Base on the statistics of Huatai mine and the condition of ＂U ＂ ventilation, the gas emission processes in the working face during the normal work time have been simulated by using fluent flow simulation software. The influence of the air flow and gas concentration distribution because of gas emission have been researched. The research might help to understand the impact of gas emission and provide the theoretic foundation for the formulation of gas emission emergency measures.
