地下辅助通风动力消耗量占矿山通风总动力消耗量的25～52%,因此,应予控制和最优化。这一动力消耗量的变化取决于矿山开采时间、用于辅助通风的辅助通风机类型、矿山管理部门关于废弃的独头巷道进行隔离或通风的决策以及采矿方法。井下机械通风问题不是选择某种通风机以满足生产要求,而是要决定哪一种通风机最合适和最经济。效率最高的矿用辅助通风 Underground auxiliary ventilation power consumption accounts for the total power consumption of mine ventilation 25 ~ 52%, therefore, should be controlled and optimized. This power consumption varies depending on the mining time, the type of auxiliary ventilator used for auxiliary ventilation, the decision of the mine management to isolate or ventilate the abandoned single-headed tunnel, and the mining method. The problem of mechanical ventilation in the well is not to choose a fan to meet the production requirements, but to decide which fan is most suitable and economical. The most efficient mining auxiliary ventilation
