Abstract

During the past several years variable speed drives have become much less expensive for higher horsepower applications. This has created an opportunity to utilize this type of system in variable load mine ventilation applications where the traditional solutions were to use "in-flight" controllable pitch fans, variable inlet vanes or constant load systems and ignore the opportunity for power savings. This paper explores the basic characteristics of each type system and some of the advantages that each system offers for specific mine ventilation applications. The relative capital cost and operating cost of each type systems are also presented.

The Application of Variable Frequency Drives to Mine Fans

Rolla, MO

During the past several years variable speed drives have become much less expensive for higher horsepower applications. This has created an opportunity to utilize this type of system in variable load mine ventilation applications where the traditional solutions were to use "in-flight" controllable pitch fans, variable inlet vanes or constant load systems and ignore the opportunity for power savings. This paper explores the basic characteristics of each type system and some of the advantages that each system offers for specific mine ventilation applications. The relative capital cost and operating cost of each type systems are also presented.
