The short wall mining machinery is the complete mechanized mining equipment whose main part is continuous miner, and it has the features of mobilizing flexibly and strong adaptability for geological conditions, so it is the main means of well mining and corner coal recycling. Electric control equipment of short wall mining machinery runs in digging working face with the machine. When it is used in explosive hazardous gas environment, its electrical equipment should meet the prescribed explosion-proof requirements. With the combination of the working experience and lessons, the paper expounds the technical points of explosion-proof electrical equipment maintenance.
