Nitrogen has an extremely important role in the safe production of coal mines. The essence of nitrogen is to inject a certain flow of nitrogen into the oxidation zone or the fire zone, so that the oxygen content is reduced to 10% or less, so as to achieve the purpose of fire prevention, fire suppression and to prevent gas explosion. With IGS Group's world advanced technology, and more than 20 years of experience, SMC-IGS provide downhole membrane nitrogen generator (MA certification), ground membrane nitrogen generator and PSA nitrogen generator.

Typical applications are:

• Eliminate the risk of gas explosion

• Reduce the role of air leakage

• Reduce the mined-out zone temperature

• Prevent spontaneous combustion of coal

• Reduce the combustion strength
