通过在山西屯留煤矿南二采区永久避难硐室进行80人、24 h载人生存试验,对地面钻孔压风供氧系统、矿井压风供氧系统和氧气瓶供氧系统的原理和效果进行了对比分析,得出永久避难硐室内氧气、二氧化碳、温度、相对湿度随时间变化规律,并且验证了硐室内各项气体指标均在规定范围内,证明了该永久避难硐室的有效性。 By carrying out 80-man and 24-hour manned survival tests in the permanent refuge chamber in the second mining area of ​​Tunliu Coal Mine in Shanxi Province, the principle and application of air pressure and oxygen supply system for ground borehole, mine air supply and oxygen supply system and oxygen tank oxygen supply system The results show that the variation of oxygen, carbon dioxide, temperature and relative humidity with time in the permanent refuge chamber can be obtained. It is also verified that the gas indexes in the chamber are all within the specified range, which proves the validity of the permanent refuge chamber .
