This underground mining refuge chamber adopts double-layer pressure-resistant steel sealed cabin structure, equipped with oxygen supply system, CO/CO2 purification unit, temperature cooling device, water and food storage area, communication system and explosion-proof lighting:
1. Anti-explosion Pressure Resistant Shell: Thickened high-strength steel cabin body, resist impact and shock wave from underground gas explosion and roof rock collapse.
2. Independent Closed Survival System: Self-circulating air purification and oxygen supply equipment, completely isolate external toxic and harmful mine gas.
3. Long Time Emergency Support: Matched with enough drinking water, food, medical kits and power supply, support 12 people safe survival for 96 hours.
4. Constant Temperature Comfort Design: Built-in cooling and heat preservation device, keep internal temperature stable under high underground rock temperature.
5. Real-time Communication Device: Reserved mine communication interface, maintain contact with ground rescue command center during disasters.
6. Standard Underground Layout: Integral split cabin design, convenient underground transportation and rapid fixed installation in mining roadway.
