Description

In underground mines, lower worker productivity, illness, andpotentially death can result from poor working environment conditions. It istherefore extremely important to design, install, and manage undergroundventilation systems with the necessary care and attention. Excess humidity,high temperatures, inadequate oxygen, and excessive concentrations ofpotentially dangerous gases can significantly affect the quality of the workingenvironment if not properly controlled. Ventilation and air cooling are neededin underground mines to minimize heat stress and remove contaminants. As minesbecome deeper, heat removal and ventilation problems become more difficult andcostly to solve. Caution: This chapter presents only a very brief overview ofthe principles of mine ventilation planning. The person responsible for suchplanning should either be an experienced engineer, or work under the directsupervision of such an engineer. Several English-language texts have beenwritten on mine ventilation since 1980 (Bossard 1982; Hall 1981; Hartman et al.1997; Hemp 1982; Kennedy 1996; McPherson 1993; Mine Ventilation Society ofSouth Africa 1982; Tien 1999). The ventilation engineer is strongly encouragedto study these references.DefinitionsSources of Heat Entering Mine AirHeat ExchangersMine-Cooling TechniquesSelecting a Mine-Cooling MethodMechanical Refrigeration PlantsMine Air HeatingMine VentilationNo. of Pages: 14
