摘要
本文以传热学理论出发,导出了井下掘进通风时风筒内空气温度的计算公式和风筒传热系数的理论计算式。通过对实测数据的回归分析,确定了胶皮风筒传热系数实用计算关系式。
Applying heat transfer theories,this paper develops equations for the calculation of air temperatures along ventilation ducts and methods for theoretical calculation of the ventilation duct heat transfer coefficient. Based on the measured data, practical equations for calculation of the ventilation duct heat transfer are also derived through regression analysis.
