摘　　要：当煤矿井下事故发生时,避难硐室可为井下工作人员提供一个安全的避险空间,供氧系统可为避难硐室内的避险人员提供最基本的生存条件保障。经研究分析,避难硐室供氧方案必须采用压风系统供氧、压缩氧气供氧(氧气瓶供氧)和备用自救器3种方式。扼要介绍了压风供氧与压缩氧气供氧两种供氧方式的供氧量计算方法、供氧原理与主要技术参数,以及气幕喷淋系统的主要功能,可供避难硐室供氧系统设计时参考。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.
