The working environment in underground mines is complex; sudden
accidents such as collapses and gas leaks can easily cause oxygen
deficiency and suffocation among personnel, so fast and stable
oxygen supply is crucial for successful emergency rescue. As the
core equipment for mine emergency rescue, the Pressure Swing
Adsorption Oxygen Generator is based on Pressure Swing Adsorption
Oxygen Generation Technology. It separates air components
selectively through adsorbents and can produce high-purity oxygen
within a few minutes. This 50kW low-power-consumption model
integrates the energy-saving advantages of VPSA Oxygen Supply
Systems, reducing power consumption by 25% compared with
traditional equipment. It also features portability, mobility and
impact resistance, which perfectly adapts to the narrow space and
unstable power supply environment in mines, building a reliable
"life defense line" for underground emergency rescue.

Why is psa oxygen generator the First Choice for Mine Emergency
Rescue?
Mine emergency rescue has extremely strict requirements for oxygen
supply equipment, namely "fast, stable and economical", and the
Pressure Swing Adsorption Oxygen Plan precisely meets these needs.
Traditional mine emergency rescue mostly relies on bottled oxygen;
a single bottle can only supply one person for 2 hours, and
transportation is difficult. In contrast, the 50kW PSA oxygen
generator can produce 480-720Nm³ of oxygen per day (24 hours),
equivalent to the oxygen volume of 3200-4800 bottles of bottled
oxygen. Meanwhile, its Pressure Swing Adsorption Oxygen Supply
System does not require liquid oxygen storage, avoiding the
explosion risk under high temperature and pressure, thus being more
suitable for the flammable and explosive environment in mines.
Compared with Vacuum Swing Adsorption Oxygen Plant, this equipment
can still maintain stable oxygen production under low-power
operation, adapting to the limited power supply capacity of mine
emergency generators.
Core Considerations for psa oxygen plant cost in Mine Emergency
Scenarios
When selecting equipment, mining enterprises focus on the
comprehensive cost in emergency scenarios in addition to the
initial investment. The PSA Oxygen Generator Price of the 50kW
model is approximately 150,000-200,000 RMB. Although it is higher
than that of small equipment, it reduces the cost by 50% compared
with the establishment of a bottled oxygen reserve warehouse. In
terms of operating cost, the energy consumption cost per cubic
meter of oxygen is about 0.36 RMB (calculated based on the
industrial electricity price of 0.6 RMB/kWh), which is only 1/4 of
that of bottled oxygen. Besides, the equipment uses special
dust-resistant molecular sieves with a service life of up to 4
years, which is much longer than that of ordinary PSA equipment,
reducing maintenance and replacement costs. For a mine with an
annual output of 1 million tons, equipping one such equipment can
save more than 100,000 RMB in emergency oxygen supply costs every
year.
Adaptability to Extreme Environments: Special Designs for Mine
Scenarios
To cope with the extreme environment in underground mines, the
equipment has multiple special designs: the body is made of
impact-resistant steel plates, which can withstand the impact of
falling rocks in the mine; the electrical system adopts
explosion-proof design, complying with the explosion-proof grade
requirements in underground coal mines; it is equipped with a
dehumidification system, which can ensure the qualified air
pretreatment even in the mine with 90% humidity; the equipment
control panel adopts a waterproof and dustproof touch design, which
can be easily operated even with gloves. In addition, the equipment
supports linkage with the mine emergency communication system; when
an accident occurs underground, the command center can remotely
start the equipment and make oxygen supply preparations in advance,
striving for precious time for rescue.
In conclusion, the 50kW low-power-consumption psa oxygen generator
has become the core equipment for mine emergency rescue due to its
advantages of stability, energy saving and portability. Through the
integration of Pressure Swing Adsorption Oxygen Production
Technology and vacuum regeneration technology, it provides
continuous and reliable oxygen support for trapped personnel in
extreme environments, which not only reduces the emergency cost of
mining enterprises but also builds a solid life defense line.
