Fuel preparation for a pc boiler occurs in a mill, where coal is typically reduced to 70% through a 200-mesh (74-μm) screen. Figure 2 shows a particle-size distribution from a bowl-mill grinder typically used in power plants. A typical utility specification for particle size distribution of the coal is that 70% of the mass should pass through a 200-mesh screen, …

Longwall mining is a highly productive, economical, and relatively safe method of coal mining. Academician Qian pointed out that as the longwall panel advances, the fractured irregular overlying rock masses and residual coal collectively form a porous medium called the gob area [1], which is illustrated in Fig. 1 (a). Inter-particle voids …
