通常在浅井煤矿通风系统设计或者通风阻力测定时,均假定空气为不可压缩流体,不考虑其压缩放热效应。但在深井条件下,开采深度所带来的风流压缩性则应予以考虑,否则有可能产生错误的结论。以庞庄煤矿张小楼井通风阻力测定得到的基础数据为依据,利用克拉伯龙方程来测算矿井通风参数,探讨在高温深井条件下矿井内部漏风率的计算方法。
Usually in shallow shaft coal mine ventilation system design or ventilation resistance determination, assume that the air is incompressible fluid, regardless of its compression radiating effect. However, under deep conditions, the wind-induced compressibility of the mining depth should be taken into account, otherwise it may lead to wrong conclusions. Based on the basic data obtained from the measurement of ventilation resistance of Zhang Xiaozhuang in Pangzhuang Coal Mine, the Kraft equation was used to calculate the ventilation parameters of the mine and the calculation method of the air leakage rate inside the mine under high temperature and high temperature was discussed.
