我国煤矿现有数千台主要通风机在运转，从』总体着运行效率普遍偏低，多数达不到50％，装置效率达70％的只占极少数，而矿井主要通风机是矿井耗电最多的设备之一．目前，矿井主要通风机运行存在一系列问题。主要表现为：设备陈旧，效率低下；“大马拉小车”；井下通风网络设计 At present, there are thousands of major ventilators in operation in China’s coal mines. From the perspective of “the overall operating efficiency is generally low, the majority is less than 50%, and the installation efficiency is only 70%, while the main mine ventilator is the mine’s power consumption One of the most devices. At present, there are a series of problems in the operation of the main mine ventilator. Mainly as follows: outdated equipment, low efficiency; ”big car"; underground ventilation network design
