通过对掘进通风机所需风量的专项逻辑推算 ,找出风机风量与风筒漏风及掘进工作面风量的正比例关系算式 ,从而导出风机风量是增变量。实际应用时应定期分阶段对风机风量调控以达到各阶段所需风量要求。 Through the special logic calculation of the air volume required for tunneling fan, find out the proportional relationship between the air volume of the fan and the air leakage of the air cylinder and the air volume of the tunneling face, so that the air volume of the fan is increased. The actual application should be regularly phased fan air flow control in order to achieve the various stages of the required air flow requirements.
