摘　　要：角联巷道一直是通风系统优化的重点研究对象。利用Ventsim软件解算多组数据,推导出角联分支风量、评判指标及风阻相互间的规律、关系,提出的最终评判指标:当K≥3或K≤0.333时,风流稳定;当1<K<3或0.333<K<1时,角联分支风量不小于总风量10%时,角联巷道风流稳定性与风量呈正比例关系。Diagonal roadway has been the focus of ventilation system optimization research. Ventsim software was used to solve the multi-sets of data, and the law of wind volume, index of judgment and windage resistance were deduced from the multi-sets of data. Finally, the final evaluation criteria were as follows: when K≥3 or K≤0.333, when 1<K<3 or 0.333<K<1, the angular airflow distribution is not less than 10% of the total air flow, the airflow stability of the roadway is positively proportional to the air volume.
