摘　　要：为分析无风墙机站通风效应,建立了无风墙机站数值分析模型,并分析了风机在不同速度下的风压效应,得出无风墙机站风机风量在小于、等于和大于巷道内风量3种情况下均能有效增加巷道内风压、提高风流动能,并验证了风压经验算法.In order to study the effects of fan station without ventilation wall,the numerical analysis model is established and the pressure effect is analyzed under different speeds. It is concluded that fan station without ventilation wall in roadway that is less than,equal to or greater than the air volume can effectively increase the air pressure in roadway,and improve the wind flow kinetic energy. In addition,the wind pressure experience algorithm is verified.
