Most important is that the shelter cave is equipped with enough food, water and oxygen. Take refuge in the cave, there are two sets of oxygen supply equipment. Constant fresh oxygen to make people feel very relaxed and very comfortable.
According to introduced, drag white coal industry limited responsibility company drag white coal mine emergency hedge system built in 1150 meters of level bottom yards, using original roadway, in permanent refuge Chamber indoor set has security protective, for oxygen, and environment purification, and refrigeration dehumidification (temperature, and humidity Regulation) power guarantees, and indoor lighting and the outdoor indicates, and pressure wind self-help, and environment monitoring, and communications contact, and water rescue, and personnel positioning, and exhaust, and survival guarantees, and subsidiary system,.
In the emergency system, there should be not lower than 0.75 square metres of usable floor area per person, design rated safe haven no fewer than 50 people. Meanwhile, access of mine pressure monitoring surveillance, locating people, wind, water, communications and electricity systems. There are number of rated safe-haven equipped with oxygen and harmful gas removal facilities, food and drinking water and self-rescue devices, lighting, kits, fire extinguishers, first aid kit, human waste collection devices and other auxiliary facilities. Equipped with food no less than 2 million KJ/person/day, not less than 0.5 litres of drinking water per person per day.
Technician Zhao Ruixu introduced at the pit building "six support systems", external can withstand high-temperature flue gas, isolated from toxic gas, internally to provide oxygen, food, water, removal of toxic or hazardous gases, creating basic conditions of existence, creating conditions for emergency rescue, to gain time.
Isolation
Two dampers to help block dangerous invasion
According to reports, the 1150 m permanent refuge Chamber bottom arch support, wall thickness is greater than 50 cm by C30 concrete casting, watering in the tunnel at around the cutting depth 30 cm; stuck between a distance of 3 metres, filled up with clay; to ensure the wall hard, crack-free, waterproof, ensuring sufficient tightness.
Export to blast doors under the refuge Chamber is 12 meters, the net width of 2.4 m clear height of 2.4 m. Walls 1.2 metres high, living room to export long 28.83 meters on the refuge Chamber, living room to export under the refuge Chamber is 42.75 m long, bench height 13.8 cm, width 40 cm, length 80 cm, slope of 19 degrees, life NET ceiling height 4 m, width of 8 meters.
