| 摘 要： | 针对高瓦斯突出矿井进行主通风机倒机时,在短暂的停机时间内仍会出现瓦斯超限现象的问题,提出了一种基于S7-300 PLC的矿井通风机不停风自动倒机系统的设计方案。该系统采用增加对空旁路风门来启动备用通风机的方案,即在主通风机停止前先启用备用通风机,通过主、副风门开度的配合,保证倒机系统风量的稳定。实际应用表明,该系统可有效保证不停风倒机过程的安全。

| Abstract: | In view of problem that high gas outburst mines would appear over-limit phenomenon of gas concentration in short stop time of ventilator when main ventilator makes switchover,the paper proposed a design scheme of automatic switchover system of mine ventilator without blowing-out based on S7-300 PLC.The system uses scheme of installing bypass air door to start standby ventilator,namely starting standby ventilator before main ventilator stops running and through coordination of open degree of main and side ai... |
