Abstract: The paper introduced characteristics and installation location of a new type of underground emergency rescue equipment, namely movable lifesaving transition station of coal mine, gave internal configuration scheme and configuration purpose of the transition station, and introduced design methods of oxygen supply system of the transition station based on three-level oxygen supply way of pressure ventilation, compressed air and self-rescuer. The transition station effectively solves personnel safety problem during disaster accidents such as gas explosion, coal and gas outburst, fire and collapse in coal mine.
