Abstract: The air supply mode of heading face based on compressed air self-rescue system supplies wind to the heading face through ground air compressor and air supply pipe. Compared with the traditional local ventilator, the air supply system of air duct, it has the advantages of good safety, high reliability and strong resistance to disaster. Through the deep study of the air supply mode, this paper provides theoretical support for the practical application of the air supply mode in the heading face based on compressed air self-rescue system.
