摘　　要：随着矿井的开采,通风系统逐渐复杂化,通风网络的安全监测与管理难度加大。为解决此问题,首先系统分析角联通风理论,以θ形经典角联为例,利用Ventsim软件解算多组数据,总结角联风量与风阻间的各规律,从而提出新的判定指标,利用Fluent软件进行数值模拟验证指标科学性,并完善判定指标。With the increasing mining of the mine, the ventilation system is gradually complicated, andthe safety monitoring and management difficulty of the ventilation network is also increased. In order tosolve this problem, firstly, the method of diagonal ventilation is analyzed systematically. Taking theclassical diagonal as an example, Ventsim software is used to solve the multiple sets of data, and therules of 0 shape air volume and wind resistance are summarized,the new evaluation index is proposed.The numerical simulation is carried out by Fluent software to verify the scientific index and improve thejudgment index.
