摘要
利用CFD软件对矿井巷道的风流场进行了三维数值模拟,揭示了不同形式巷道风流速度分布特征,分析了监测点风速与平均风速的关系,确定了风速监测数据修正系数,为矿井利用传感器准确监测巷道风量提供了有力保障。
Using CFD software to 3D simulate the airflow in mine roadway,revealed distributive characteristic of airflow velocity in different forms of roadways,analysed the relations between the average of airflow velocity and monitoring data,identifed amendatory coefficient from monitoring data.The result provides strong security for using sensors to monitor airflow flux in roadway.
