摘　　要：针对五阳煤矿7802工作面综放开采过程中存在的瓦斯超限问题,采用数值模拟和理论分析相结合的方法,对工作面风流流场及瓦斯分布进行深入研究,揭示了U型综放工作面风流的流动规律和瓦斯运移规律,同时找出了工作面回风上隅角瓦斯积聚的主要原因,并针对该主因提出了相应的防治措施。To counter the disallowed gas concentration in 7802 fully mechanized caving face of Wuyang Coal Mine,deep study was made on the air flow field and gas distribution in the face through numrerical simulation and theoretical analysis.The study results revealed the air flow and gas migration law in a U-shaped fully mechanized caving face and found out the main reasons for gas accumulation in the upper corner angle of the face.Finally relevant prevention measures were put forward according to this main reason.
