The invention discloses an automatic shutdown control method for fully mechanized mining face production devices of underground coal mine. In the method, shutdown mechanism and latch-up protective mechanism of the fully mechanized mining face production devices are designed. In a normal shutdown process, the load quantity of the device is determined according to the collected current of a transportation device in real time, and according to a shutdown principle of shutdown along with coal flow sequence. When the load quantity of one device is zero, the device is instantly shut down, and then the load quantity of a next device is determined. When a device is in failure suddenly, the corresponding latch-up protective mechanism can be started timely; and according to the protection principle that the devices in failure, which are countercurrent to the coal flow direction, are emergently shut down and the devices in failure, which are parallel with the coal flow direction, are shut down according to sequence, the
