Paul Elswick started Paul's Fan Company in 1958. During this time Paul repaired underground mine equipment, trucks, and anything else he could get his hands on. When demand for mining equipment jumped in the mid60's, Paul developed the MarkIV roof bolting machine.
Fan duct to deflect air to recover fan velocity pressure > 80 ft Surface Mine fan Bulkhead. Figure 910. Fan duct is used to deflect exhaust air and to recover lost velocity pressure. Figure 910 shows a suggested layout where exhaust air is deflected upward using .
Motor Selection. Ventilating underground excavations is quite different from ventilating a building. If the project proceeds as planned, the area to ventilate grows every day and the vent system should, in most cases, do the same. Moving fans and extending ducting is an essential part of the process.
Industrial Mine Ventilation fans are used primarily for underground mining operations. Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove noxious gases. Flowthrough ventilation is the main ventilation circuit for the mine.
VSDs to vary ventilation fan speeds in underground mining are presented in [19, 29, 30]. These studies explore the concept of ventilation on demand (VOD). The idea is to allow variable air ow by adjusting the speed of the fan over time (based on the demand), as opposed to running them at .
The fan isinstalled at a point at least 10 m (33 feet) upstream in the general mine air circuit (Figure 3). The volume of intake air available should be times the fan capacity. In order to avoid damage when blasting, the last section of tubing (at least 15 m 50 ft) is taken down to a safe distance from the blast.
