Background
The coal mine underground compressed air self-rescue system is an appliance which utilizes a mine compressed air (compressed air) pipeline system, is connected with a branch pipe, is connected with a protective bag, a face mask or a bell mouth and other masks connected with human respiratory organs, supplies compressed air to refuge miners after pressure reduction, throttling, noise elimination and filtration and protects the refuge miners from being invaded by toxic asphyxiant gases. When the catastrophe occurs in the early stage, whether catastrophe needs to occur or not can not be distinguished by human senses, so that personnel cannot respond timely in the face of catastrophe conditions, a corresponding emergency treatment scheme cannot be made, and even casualties are caused. Therefore, the existing compressed air water supply self-rescue device installed on the driving working face has certain defects, cannot give an alarm in advance in the early stage of catastrophe, and cannot carry out self-rescue in the first time. Therefore, the invention needs to invent the airborne compressed air self-rescue device which can automatically start the compressed air self-rescue system once a disaster occurs or the health condition of workers is damaged, and the workers in the disaster range can get to the compressed air self-rescue system to avoid the disaster, and has great significance for ensuring the safe production and improving the working efficiency.
