摘　　要：本文针对自燃煤层U型通风系统工作面上隅角瓦斯积聚现象,采用ANSYS数值模拟对瓦斯浓度与风速的关系进行研究,并根据工作面内瓦斯积聚规律,实施了U型通风系统采空区瓦斯抽采技术,通过工程实践证明此方案能够有效解决U型通风系统工作面上隅角瓦斯积聚的现象。According to the accumulation of gas in the coal spontaneous combustion of U type ventilation system in upper corner, using the ANSYS numerical simulations to study the relationship between the gas concentration and wind speed, and according to the law of gas accumulation in the working surface, the design of U type ventilation goaf gas drainage technology, through the engineering practice has proved that this design scheme can effectively solve U type ventilation system on the working face of the corner gas accumulation phenomenon.
