摘　　要：对大面积采空区综放工作面回风隅角瓦斯涌出原因进行了分析,通过封堵隅角,调整通风系统,增加风量,构筑通风设施,改变大面积采空区压力分布,降低回风隅角压差,减少采空区积存的瓦斯向回风隅角的流动和泄漏,降低回风隅角瓦斯浓度。对类似矿井工作面回风隅角瓦斯防治具有较好的借鉴意义。The reasons for gas emission from the return airway corner of the fully mechanized caving face in large-scale goaf are analyzed in the paper.By sealing the corner,adjusting the ventilation system,increasing the air volume and constructing ventilation facilities,the pressure distribution of the large-area goaf has been changed,and pressure difference and gas concentration of return airway corner are also reduced,which has a good reference for the prevention and control of gas in return airway corner of similar mine face.
