提高巷道风量测定精度的最大风速法

采用测定巷道中心最大风速的方法获得巷道平均风量,首先推导出巷道最大风速与巷道平均风量的相关关系,给出了风速分布系数的测定与计算方法、适用范围。使用该方法测风可提高测风的速度与精度,减少测风误差,还可将风速传感器获得的风速直接转化成风量,实现对矿井风量的监测监控。

The Maximum Wind Speed Method to Improve Determination Accuracy of Roadway Air Volume

In this paper,it obtained roadway average air volume by using the determination method of roadway center maximum wind speed.First,it deduced the correlation of maximum wind speed and roadway average wind volume,then gave determination,calculation method and applicable scope of wind speed distribution coefficient.This method could improve the speed and accuracy of wind measurement,reduced measurement error,the wind speed obtained from wind speed sensor was also directly converted into air volume,which realized the monitoring and control of mine air volume.
