摘　　要：为提高煤矿安全防护水平和矿井抗灾变能力,国家煤监局提出在井下设置紧急避险设施.基于山西潞安集团常村矿"N3永久避难硐室",对避难硐室压风供氧系统性能进行研究,进行了40人8h生存验证试验.试验包括压风系统供氧试验和静场试验.通过压风系统供氧试验总结了O2,CO2,温度随时间、压风风量的变化规律,并发现心理因素对环境参数的影响.通过静场试验获得了CO浓度变化速率与隔绝防护时间的关系,温度变化速率与煤层导热性的关系.In order to improve the level of coal mine safety protection and the ability to resist disaster, the State Administration of Coal Mine Safety proposes to set up emergency necessity facilities. Based on Changcun Coal ＂N3 permanent refuge station＂ in Shanxi Lu＇ An Group, this paper studies the function of compressed air supply system of the chamber, and carries out survival tests of 40 persons for 8 h. The tests include compressed air supply test and static space test. By compressed air supply test, it summarizes the variation regularity of O2, CO2 , temperature with time and the volume of compressed air. It also finds the effect of psychological factors on environmental parameters. By static space test, it obtains the relationship between CO2 concentration change rate and isolation protection time, and the relationship between temperature change rate and coal thermal conductivity.
