ZITRON has supplied fans to mining projects ranging from Ø 600mm to Ø 5,200mm, with 15kW up to 2,000kW motor power from Siberia and Chile to Australia and North America. The fans are manufactured with either horizontal or vertical configuration. Many of these fans have been installed underground to provide ventilation for mining and ...

Ductwork through smokestop or fire fighting lobbies Ventilation ducts should not pass through smokestop or fire fighting lobby. Where unavoidable, the part of the ventilation duct within the lobby shall be enclosed in construction with fire resistance rating at least .

Ordinary heating, ventilating, and air conditioning duct systems read air pressures at psi or less, often much less. 1 psi equals inches of water gauge; a common duct pressure of inches water column is equal to ( divided by inwc/psi) = psi. Duct Pressure: Duct system is pressurized by three pressures: •

 · (Ref.: The mine ventilation practitioner's data book; ed. Dr. Patterson; Mine Ventilation Society of South Africa, 1992) For primary fan, it is preferable to install two units in parallel than a single unit. The reason is that, in parallel association, a fan will produce 66% of the flow while the other is blocked for repairs.

Epiroc offers complete ventilation solutions for tunneling ventilation and underground ventilation, including system design and installation of fan stations and flexible ventilation ducting. Check out our uncerground ventilation solutions.

Background. The main objective of an underground mine ventilation system is clear: to provide air flows in sufficient quantity and quality to dilute contaminants to safe amounts/concentrations where personnel are required to travel and work. This requirement is integrated into the mining law of those nations who possess that type of legislation. The degree of "quality' and "quantity" varies ...

UVS's VENTCHOKE is designed to be installed within an existing secondary vent ducting. It is pneumatically operated and uses lowpressure compressed air to inflate an annular ring constricting device to stop or redirect the flow of secondary ventilation in underground mines. When personnel or machinery are operating in one specific area of ...

Mine, tunnel and underground sites see a great deal of industrial activity and large, heavy machinery can cause damage to ventilation ducts. Ventilation ducts need immediate repairs to ensure they provide a reliable and high level of fresh air to workers. Jensen supplies ventilation duct repair sleeves to cover a large damaged section.

Our Serpent Ventilation System has been tried and tested in hundreds of underground installations. The system is composed of highly efficient, lownoise fans and durable PVCcoated ventilation ducting. Our experts can help you design and install low cost ventilation to reduce your energy consumption by up to 50% and to help reduce the carbon ...

Ventilation plans for underground mines. The manager of an underground mine must ensure that a plan of the ventilation system at the mine is kept at the mine that shows the direction, course and volume of air currents, and the position of all air doors, stoppings, fans, regulators and ventilating devices, in the mine.
