Thermal performance of an ice storage device for cooling compressed mine air in high-temperature mine refuge chambers

•An ice storage device was developed for cooling mine compressed air in mine refuge chamber (MRC).•The device with 18 heat exchange tubes has a high ice melting rate of 85 % within 96 h.•Inlet air velocity from 5 to 15 m/s increased ice melting rate by 16.36 %.•Mixed air supply can extend the effective cooling time of the device to 96 h.•For MRC with an initial surrounding rock temperature of 32 °C, the mixed air supply makes the device satisfy 15 people.
