摘　　要：基于偏W型通风形式及其瓦斯治理的特点和作用,以太岳煤矿2201工作面为研究对象,采用FLUENT计算模拟不同中间巷位置下采空区瓦斯的涌出规律和瓦斯浓度分布,并研究了中间巷的位置对采空区瓦斯涌出形式、涌出范围及采空区内部瓦斯分布的影响。模拟结果表明:在考虑满足煤体支护强度、控制采空区瓦斯涌出形式和涌出区域要求的条件下,确定了中间巷的合理位置为L=18m,此时,采空区瓦斯涌出可限制在回风巷附近的9m范围之内,且采空区内部瓦斯集中于回风巷区域,有利于采取抽放治理措施,防止工作面瓦斯超限。Based on the characteristics and functions of the partial W-type ventilation and its gas control,taking the 2201 working face of Taiyue Coal Mine as a research object,FLUENT was used to simulate the gas emission law and gas concentration distribution in the goaf under different middle lane positions.Then,the influence of the middle lane position on the gas emission pattern,the gushing range and the gas distribution inside the goaf was studied.The simulation results showed that under the conditions of satisfying the support strength of coal body,as well as controlling the gas emission pattern in the goaf and the requirements of the gushing area,the reasonable position of the middle lane was determined as L=18 m.At this point,the gas emission in the goaf can be limited within 9 maround the return airway,and the gas in the goaf was concentrated in the return airway,which was conducive to take drainage and control measures to prevent gas overrun in the working face.
