根据AQ 6201—2006煤矿安全监控系统通用技术要求的规定,当煤矿掘进巷道内瓦斯浓度≥3.0%,局部通风机停止运转,2个条件都具备时对局部通风机闭锁使之不能启动,防止“一风吹”。在实现、运用该功能时,存在安全监控系统控制逻辑设计不合理,现场应用不易实现、易造成风机误停、无法周期调校测试的问题。以KJ100NA安全监控系统和林南仓矿井实际为例,阐述“3%闭锁”控制的设计与现场实现。 According to AQ6201-2006 coal mine safety monitoring system requirements of the general technical requirements, when the coal mine roadway gas concentration ≥ 3.0%, the local fan stop running, the two conditions are met when the local ventilation fan closed so that it can not start to prevent “A wind blows.” In the realization, the use of this function, there is safety control system design logic control system is not easy to achieve on-site applications, easy to cause fans stop, can not be adjusted periodically test problems. Taking KJ100NA safety monitoring system and Linnancang mine as an example, the design and field implementation of “3% lockout” control are described.
