矿井通风直接影响着煤矿的安全生产。在通风系统优化与通风网络解算中,确定通风构筑物的等效风阻有着重要的意义。通过分类统计所观测的数据,对构筑物等效风阻的影响因素进行详细的分析。以流体力学为基础,构建数学模型,运用CFD软件数值模拟出构筑物在不同条件下风量与压力的关系,并最终得到其函数关系。现对局部阻力的理论研究具有一定的参考价值。
Mine ventilation directly affects the safety of coal mines. In the ventilation system optimization and ventilation network solution, to determine the equivalent wind resistance of ventilation structures is of great significance. According to the data observed by classification statistics, the influencing factors of equivalent wind resistance of structures are analyzed in detail. Based on the fluid mechanics, a mathematical model is constructed. The CFD software is used to simulate the relationship between the air volume and the pressure of the structure under different conditions, and finally the function relationship is obtained. Now the theory of partial resistance has some reference value.
