The most important thing in mine work is to ensure safe operation. This is a major issue related to the life safety of miners and cannot be sloppy.

People who understand mine work may know that in normal mine mining operations, flammable and explosive gases are often produced, which makes mine operations dangerous. A common and effective way is to use nitrogen to isolate harmful and explosive gases to prevent danger. The principle of mine nitrogen explosion prevention is to inject a certain amount of nitrogen to quickly reduce the oxygen content in a certain area to below 5%, thereby achieving the purpose of fire prevention and suppressing the explosion of dangerous gases such as gas.

The way to continuously provide nitrogen can be solved by the PSA nitrogen making system; in most cases, this type of nitrogen making machine will be designed to use explosion-proof treatment for motors, electrical controls, nitrogen making hosts, etc., and at the same time, sparks caused by electrical grounding and short circuits of electrical equipment, arcs and dangerous gases must be prevented from contact. In addition, considering the mobility and convenient installation of the explosion-proof PSA nitrogen making machine, the PSA nitrogen making machine will also be skid-mounted to facilitate the use of multiple working faces or mines.

For PSA nitrogen generators used underground, the country actually has a series of strict standards and specifications, and implements a certification system; only explosion-proof nitrogen generators made in strict compliance with national standards can prevent accidents to the greatest extent; this also puts forward higher requirements on the professional capabilities of PSA nitrogen generator manufacturers. Of course, although the explosion-proof nitrogen production system can meet the safety needs of underground operations, the customization cost and price are relatively expensive. In the case of insufficient budget, it is also possible to use nitrogen production on the well to input it into the underground. This method only requires the use of an ordinary PSA nitrogen production system, and it also complies with relevant regulations.
