通过模型计算确定了避难硐室 CO2生成速率、耗氧率与压风供风量的关系,结合相关研究确定了影响压风供风量的关键因素和因素控制水平.根据密闭空间 CO2平衡方程、O2平衡方程、CO2稀释方程、通风降温方程,并结合相关规范确定了密闭空间理论人均供风量,通过100人载人试验确定了避难硐室的最小供风量.结果表明:避难硐室供气量与人数有关,与硐室体积无关,确定以 CO2时间加权阈限值0.5%为避难硐室控制水平,100人避难硐室最小供风量不小于600 m3/h.

@@@@Based on the model calculations, this study obtains the relationships among CO2 production rate, oxygen consumption rate and air volume in a mine refuge station. Furthermore, the study confirms the key factor and the factor control level which has effect on the air volume. According to the CO2 equilibrium equation, O2 equilibrium equation, CO2 dilution equation, ventilation cooling equation in confined space, and various related standards, this study obtains the average theoretical air volume in a confined space. Through a real experiment involving 100 people, the minimum air volume of a mine refuge station is found. The study results show that the air volume of a mine refuge station is related with the number of people and has nothing to do with the volume of a mine refuge station. The control level of a mine refuge station is that the time weighed threshold limit of CO2 is 0.5%. The minimum air volume of a mine refuge station for 100 people is 600 m3/h.
