本文叙述了矿井通风网路的一般性质及其相似理论的基本原则。由于现代化矿井生产率的不断提高和矿井的加深,致使通风费用大大增加。耗费于巷道通风的功率是与矿井气体动力阻力和风量成正比。因此,合理地分配进入矿井的空气量可以大大地降低电能消耗。为了选择较为合理的矿井巷道空气分配方案,必需正确地计算空气沿巷道网路的分配。
This paper describes the general nature of mine ventilation networks and the basic principles of their similarity theory. Due to the continuous improvement of the productivity of modern mines and the deepening of the mines, ventilation costs have greatly increased. The power dissipated in the tunnel ventilation is proportional to the mine gas dynamic resistance and air volume. Therefore, a reasonable distribution of the amount of air entering the mine can greatly reduce the power consumption. In order to choose a more reasonable mine roadway air distribution scheme, the distribution of air along the roadway network must be correctly calculated.
