摘要
为保证矿井的安全生产,各用风地点适当的风量配定是通风管理的重要内容,而精确测定井巷平均风速则是正确配风的一个主要环节。通过实验建立了风机巷道风口出口端单点风速与风机巷道平均风速之间的回归方程,并对拟合效果进行了评价。评价结果证明该方程是有效的,可以把风机处单点风速测量值近似转换为风机处巷道的平均风速值。
In order to guarantee the safety production in pit, appropriate air volume in wind points is an important part of ventilation management while precise measurement of the average wind velocity in the tunnel is a main link in appropriate air arrangement. The regression equation between the single point wind velocity at the exit end and the average wind speed in the wind tunnel was established through experiments. And the fitting effect was evaluated. Evaluation results show that the equation is valid and it helps convert the single point wind velocity into the approximate average wind velocity in the tunnel.
