Kohmer Why Jet Fans Are Ideal for Underground Mines and Industrial Facilities ? Ventilating vast, enclosed spaces is one of the most difficult engineering challenges in the industrial world. Whether it is a deep underground mine shaft, a kilometer - long tunnel, or a sprawling manufacturing plant, the issue remains the same: how do you move massive volumes of air without filling the space with obstructive ductwork? For decades, the answer relied on complex networks of pipes and ducts. However, modern engineering has shifted toward a more efficient, flexible solution: the jet fan. The Pow er Of Impulse Ventilation Unlike traditional axial fans that rely on static pressure to push air through a physical duct, jet fans operat e on the principle of impulse. They are essentially small, high - velocity fans that produce a powerful thrust of air. This high - speed jet entrains the surrounding stagnant air, creating a continuous flow or "virtual duct" that moves air toward the exhaust p oints. This technology is revolutionary for underground mines and large industrial facilities for three key reasons: 1. Eliminating Ductwork In an underground mine, headroom is precious. Installing bulky ventilation ducts limits the clearance for heavy mac hinery and trucks. Furthermore, ducts are prone to damage from rockfalls or vehicle collisions. Jet fans are mounted flush against the ceiling or walls, leaving the operating clearance completely unobstructed. This "ductless" approach significantly reduces installation costs and maintenance headaches. 2. Tackling Dead Spots and Fumes Industrial facilities and mines are full of "dead spots" — corners where air stagnates, and pollutants accumulate. In mines, this can mean a buildup of blasting fumes or diesel p articulates. In factories, it might be heat pockets or chemical vapors. Jet fans can be strategically positioned to blast air into these specific dead zones, ensuring a uniform sweep of fresh air throughout the facility. 3. Smoke Control and Safety In the event of a fire, ventilation becomes a life - saving system. Jet fans are critical for smoke extraction. Most are designed to be reversible and heat - resistant. They can direct smoke away from escape routes, providing a clear path for evacuation while allowin g emergency responders to access the site safely. This capability is why safety standards heavily rely on data from established jet fan manufacturers to ensure fans can operate even during high - temperature emergencies.
