Abandoned mines exist throughout the country, with approximately 300,000 abandoned mines located in the Appalachian region. Abandoned mines create safety concerns for active underground mining operations and surface facilities.
fans in underground mines (Calizaya, et a/., 1987). There after, a computer program for the selection of the optimum combination of fans and regulators in underground mines was developed (Calizaya, et a/., 1988). Moll and Lowndes ( 1994) investigated the application of this method to a study of booster fans in underground UK coal mines.
