In all cases, the analyses utilize pressure-volume (PV) and temperature-entropy (Ts) diagrams. This chapter assumes familiarity with the basic concepts and relationships that are developed in Chapter 3.

Underground Mine Ventilation Technical Aspects of Mining

In mechanical ventilation, pressure difference is created by operating one or more fans in an airway. Each fan creates a certain amount of pressure, and that pressure is gradually lost as the air passes through the airway against its resistance. Most mining fans are of one of two basic designs.
