煤矿主扇是矿井的“肺” ,不得停止运行 ,应与矿井同寿命。为了保证煤矿正常开采 ,必须 2台互备运行数十年 ,甚至近百年。况且 ,煤矿不少是超级和三级瓦斯矿 ,防爆问题尤为突出。总之 ,矿井主扇的运行可靠性与安全性对煤矿来说是第一位的。另外 ,矿井主扇又是耗能大户 ,要求高
The main fan of the coal mine is the “lung” of the mine, which can not be stopped and should have the same life with the mine. In order to ensure the normal mining of coal mines, two units must be operated for several decades or even nearly a hundred years. Moreover, many coal mines are super and three gas mines, explosion-proof problem is particularly prominent. In short, the main fan of mine operation reliability and safety is the first of mine. In addition, the main fan is energy-hungry, demanding
