Abstract
This study describes the principles involved in the design of a booster fan installation, the basic requirements, and the provisions needed to guarantee safe operation of the unit. It also describes how a booster fan should be selected and what measures should be taken so that events such as uncontrolled recirculation of air in a mine can be avoided. A computer program called mfselect is presented to assist the ventilation engineer in the design process. For a given mine ventilation network, the program determines the duties of fans and regulators that will fulfill the airflow requirements of a mine and minimize the total power comsumption. The application of the program is illustrated by the detailed solution of a sample problem. A case study based on the Jim Walter Resources' No. 7 Mine is utlized to describe the basic requirements for the design and operation of booster fans and illustrate their potential benefits in mine ventilation. Finally, the study discusses a process control system designed to evaluate the safety conditions in the mine and report on the status of both surface fans and underground booster fans.
