Design on Oxygen Supply System of Mine Refuge Chamber
ZHAO Chen-de
Abstract：When an accident occurred in an underground mine ,a refuge chamber could provide a safety refuge space for the personal in the underground mine and the oxygen supply system could be a protec-tion to provide a basic living condition to the refuge personnel in the refuge chamber .T he study and a-nalysis showed the oxygen supply plan of the refuge chamber should have three methods ,including the oxygen supply with a compressed air system ,the compressed oxygen supply (oxygen supply with oxy-gen cylinder) and the standby self rescuer .The paper briefly introduced the calculation method of the oxygen supply quantity ,the oxygen supply principle and main technical parameters for the compressed air oxygen supply method and the compressed oxygen supply method and introduced the main func-tions of the air curtain and spraying system .The introductions could be references to the design on the oxygen supply system of the mine refuge chamber.
