The mine air curtain is a kind of good wind control technology.But there is on profound research on mine air curtain,the structural design of the air curtain and the determination of its parameters also only depend upon actual experiments and analysis with too much limitation.The simulation analysis of air flow field in mine air curtain was carried out using the finite element analysis software ANSYS,and the velocity and pressure distribution of the air flow field were obtained,which provide a theoretical basis for choosing the more reasonable structure parameters of mine air curtain.
