由于矿井主扇的功率很大和运转的不间断性,故其工作状态的经济性问题至关重要。显然,保障矿井的空气供给应当与改善通风设备的经济指标相结合。现在我们可以把实际的功率单耗比作生产压缩空气的类似指标,而克里沃罗格矿区各矿主扇电能的非生产损失占通风电能总值的25％。作为控制对象的主扇,其特点是有大量因素影响工作状态的稳定,工作状态输出参数的相关性,以及补偿干扰进行挖制的有限可能性。上述因素的综合作用使主扇风量比
Due to the power of the main fan of the mine and the uninterrupted operation, the economic problem of working condition is of crucial importance. Obviously, ensuring mine air supply should be combined with economic indicators to improve ventilation. Now we can compare the actual power consumption to a similar indicator for the production of compressed air, and the non-production loss of the primary fan energy at each mine in the Krivollo mining area accounts for 25% of the total value of the ventilation energy. As the main fan of the control object, there are a large number of factors that influence the stability of the working state, the correlation of the working state output parameters, and the limited possibility of digging for compensating for the disturbance. The combined effect of the above factors make the main fan air volume ratio
