摘　　要：以"简化版"避难硐室为基础,构建了避难硐室不同供气系统下的CO2、O2浓度的数学模型,并结合小梁沟煤矿永久避难硐室具体情况,定量分析了CO2、O2的浓度变化情况,并在现场进行了小梁沟避难硐室安全避险综合模拟,根据现场监测气体浓度变化与理论分析值进行了分析和比较,验证了仅在压风供气系统下能够保障安全避险人员氧气需求。Based on＂a simplified version＂of refuge chamber,the paper established the mathematical model of CO2,O2 concentration under different gas supply system in the refuge chamber. Combined with the specific circumstances of the permanent refuge chamber of Xiaolianggou Mine, quantitatively analyzed the concentration change of CO2,O2,and carried out the synthesis simulation on the safety hedge in the permanent refuge chamber of Xiaolianggou Mine. According to the comparison of the field monitoring results of the concentration changes with theoretical value,the compressed air supply system could guarantee the oxygen supply.
