首先,是在不知道最佳压力的情况下求出低于最佳压力值时的两台风机压力。第一次将辅扇的压力设为零,鉴别临界分支巷道,优化主扇压力。然后设定一个辅扇压力值,重复上述计算过程。在该辅扇压力条件下选定为临界分支巷道的工作面与辅扇压力
The first is to find the two blower pressures below the optimum pressure without knowing the optimum pressure. For the first time, the pressure of the auxiliary fan is set to zero to identify the critical branch roadway and optimize the main fan pressure. Then set a secondary fan pressure value, repeat the above calculation. In the auxiliary fan pressure conditions selected as a critical branch roadway and auxiliary fan pressure
