Study and Analysis of Human Survival Parameters in Mine Refuge Station

In order to study life support key techniques in mine refuge station, test the clinical emergency response of participants and human survival parameters in rescue state. A manned test with 50 miners for 48h in a real underground refuge station was conducted in Guilaizhuang gold mine. The experiment simulated rescue living environment of human and consisted of three stages (the passive stage, the compressed air supplying stage, and the compressed O supplying stage). By monitoring environmental concentrations of O₂, CO₂, temperature, relative humidity, and human activity states during the test, the O₂ consumption, CO₂ production and respiration quotient was obtained and analysed in different activities, time quantum and O₂ concentration. On the basis, the minimum air supply volumes for the survival of test personnel were determined. That is 0.067m/min per person and is far lower than the national standard 0.3m/min per person. During the test, no people experienced discomfort by health check and questionnaire. It is expected that the conclusions provide an important reference for the design of underground refuge stations and mine emergency rescue.
