Analysis on Theoretical Model for Mine-use Air Curtain in a Mine

Using Matlab language,the 3D chart of a mathematical model for air curtain of obstructive or inductive airflow is drawn.The relationship between inductive airflow amount of air curtain Q and fan quantity n,export wind speed Vc,ventilation resistance of air curtain-built drift △H,wind resistance of workings R,and air-export section Sc is analyzed in 3D coordinate system.In addition,the characteristics of obstructive or inductive airflow of air curtain are experimentally studied,which can provide a reliable guide in theory and technique for actual application of air curtain in mines.
