针对龙门煤矿目前井下的电气控制中,防爆按钮的使用非常广泛,用于控制设备的启动、停止,斜巷绞车运行过程中红灯的开停等,按钮控制的设备、红灯等的自保主要依靠继电器控制,其投入成本高,事故率也高,安全可靠性差,针对以上问题研究开发煤矿防爆按钮锁定装置可以实现操作防爆按钮过程中有效闭锁,保障广大煤矿职工的人身安全,为建设高产高效矿井、安全生产发挥重要作用。
In view of the current underground mine electrical control in Longmen Coal Mine, the use of explosion-proof pushbuttons is very extensive and is used for controlling the starting and stopping of equipment, the red light on and off during the operation of inclined winch, the button-controlled equipment, Mainly rely on the relay control, the high cost of its inputs, the accident rate is high, poor safety and reliability, research and development of coal mine explosion-proof button locking device for the above problems can be achieved in the operation of explosion-proof button in the process of effective closure to protect the general coal mine workers, personal safety, Efficient mine, safety play an important role.
