摘　　要：通过对通风机掘进迎头供风、风筒转换装置的原理与结构、双电源转换开关的工作原理以及风电闭锁等系统的组合,提出了掘进迎头双风机双电源的改造方法,使掘进迎头实现了双风机双电源装备的目标,能够实现风机的自动切换。从根本上杜绝了掘进迎头的无计划停风,保证了掘进迎头安全生产。This paper discussed the signiifcance of fan for the heading ventilation , the principle and structure of fan conversion device, the working principle of dual power transfer switch the through the on face for the wind to, and the wind and gas electricity closed-cycle control safety monitoring system, proposed the method of transformation of dual power double fan in heading, achieve the goal of a double fan double power equipment, realized the fan automatic switching . Fundamentally prevented the heading unplanned stopping wind; and ensured the safety production of heading face.
