摘　　要：为研究不同配风量下Y型通风的采空区风流场,以张集煤矿1613A工作面为工程背景,通过Fluent数值模拟对工作面在总配风量为1350 m^(3)/min、1800 m^(3)/min、2700 m^(3)/min时的采空区漏风规律进行研究。模拟结果表明,随着总配风量的增大,采空区整体的漏风速度增加,且采空区前部漏风速度比尾部漏风速度增长快,留巷侧采空区漏风速度比回风侧采空区漏风速度增长快。研究成果为张集矿制定防漏风措施、提高风流效率提供了有效依据。In order to study the wind field of Y-type ventilation under different air distribution,taking 1613A working face of Zhangji Coal Mine as the engineering background,numerical simulation of Fluent is used to study the air leakage law of the goaf when the total air distribution of the working face is 1350m^(3)/min,1800m^(3)/min and 2700m^(3)/min.The simulation results show that the air leakage velocity of goaf increases with the increase of total air distribution,the air leakage velocity in the front of the goaf increases faster than that in the tail of the goaf,and the air leakage velocity in the goaf on the retaining side increases faster than that in the goaf on the return side.The research results provide effective basis for Zhangji Coal Mine to formulate air leakage prevention measures and improve air flow efficiency.
